New R&S LCX strengthens Rohde & Schwarz portfolio for high performance impedance measurements

Posted on by mixos

With a completely new family of high performance LCR meters, the frequency range of impedance measurements provided by Rohde & Schwarz test equipment is dramatically extended to cover AC components operating from 4 Hz to 10 MHz, supporting all practical applications.

The R&S LCX family of LCR meters serves all established impedance measurements plus specialized measurements for selected component types and provides both, the high accuracy required in R&D, and the high speed needed in production test and quality assurance.

Rohde & Schwarz launches its new LCR meter family of high-performance general-purpose impedance testers covering a wide range of applications. With its supported frequency range from 4 Hz to 10 MHz, the R&S LCX is suitable not only for the vast majority of devices operating at conventional 50 or 60 Hz domestic power frequencies or 400 Hz for aircraft but also for everything from low-frequency seismic sensors to high power communication circuits operating at several Megahertz.

For engineers selecting suitable capacitors, inductances, resistors, and analog filters to match the device application, the R&S LCX models provide high precision impedance values with market-leading accuracy. Equally, higher speed measurements at production-use accuracy for quality control and monitoring are also supported. All the essential software and hardware required for production environments is available, including remote control and result logging, as well as rack mounting for the instrument, and a full range of test fixtures for handling components.

The auto-balancing bridge technology used by the R&S LCX supports conventional impedance measurements by measuring the AC voltage and current for the device under test, including the phase shift. This is then used to calculate complex impedance at any given operational point. As a general purpose LCR meter, the R&S LCX covers many applications, such as the measurement of equivalent series resistance (ESR) and equivalent series inductance (ESL) of electrolytic capacitors and DC-link capacitors. Furthermore, users can test transformers and measure DC resistance in addition to the full range of impedance measurements. To investigate components with impedance values varying at different frequencies and levels, option R&S LCX-K106 supports dynamic impedance measurements with the frequency, voltage or current as the swept parameter.

The R&S LCX family is launched with two models; the R&S LCX100 covers a frequency range from 4 Hz to 300 kHz, the R&S LCX200 a basic frequency range from 4 Hz to 500 kHz with options to cover all frequencies up to 10 MHz. Both models feature a large capacitive touchscreen and virtual keyboard to support tap-and-test for all main measurements. Alternatively, voltage, current, and frequency values can be set using the rotary knob. Less frequently used functions are menu-operated. Settings, results, and statistics can be displayed on the screen or output for automated post-processing. Up to four measurements can be selected and plotted versus time, with minimum and maximum values included in the display for at-a-glance pass/fail analysis.

For investigating impedance in a wider range of materials, the MFIA impedance analyzer from Zurich Instruments AG, a subsidiary of Rohde & Schwarz, complements the R&S LCX perfectly. With the MFIA researchers can characterize semi-conductors or undertake material research into materials including dielectrics, piezoelectrics, ceramics and composites, as well as tissue impedance analysis, cell growth, food research, microfluidics, and wearable sensors.

The R&S LCX family of LCR meters is part of the R&S Essentials portfolio and is now available from Rohde & Schwarz and selected distribution partners.

3-Phase Brushless DC Sinusoidal Sensorless Fan Motor Driver

Posted on by mixos

Driving a low current 3 phase brushless Sensorless DC motor is very easy with this project. This Full-wave BLDC driver project is capable to drive low current brushless fan motor without a hall sensor. 180° sinusoidal drive, high torque output, and silent drive are a few key features of the project. Due to their adaptive features and wide power-supply range capabilities (3 to 12V) they are intended to cover a wide range of motor characteristics while requiring no external tuning from the user. Speed control can be achieved through either power supply modulation or pulse-width-modulation (using the PWM digital input pin5 of CN1). Due to the compact packaging and minimum bill-of-material (power transistors incorporated, no Hall sensor, no external tuning), the project is best suited for low-cost fan applications requiring high efficiency and low acoustic noise, such as CPU cooling fans. The frequency generator output is also included, enabling precision speed control in closed-loop applications. Motor over-current limitation, short-circuit protection, and thermal shutdown protection is also included. Connect 3 Phase Motor to CN2, Apply Motor Supply to GND and VCC of CN1, Apply PWM signal to PIN 5 of CN1. D1 Power LED.

ELSYS is launching ERS Eco, a battery-free sensor line powered by Epishine’s indoor solar cells.

Posted on by mixos

Industry leading LoRaWAN sensor provider ELSYS is launching their first battery-free products using Epishine’s indoor light energy harvesting solution. The environmentally friendly sensor line is launching two sensor types called ERS Eco and ERS Eco CO2. They are entirely powered by Epishine’s indoor solar cells and are made from biodegradable materials.

“We are incredibly excited to release a new product line powered by indoor light and made of more durable materials. Combining a great solar cell with new technology and sustainable materials is completely in line with how we at ELSYS want our product development to be. We are proud to present a new product that will simplify installation and maintenance while reducing the CO2 footprint.” says Peter Björk, CEO at ELSYS.

The ERS ECO series enables customers to have complete control over their air quality and indoor environment. This in itself saves money and reduces its CO2 footprint, and its battery-free operation reduces the CO2 footprint even further.

ELSYS’ vision of making an environmentally friendly sensor, demanded battery-free operation, and a more sustainable enclosure design. The solution was cooperation between ELSYS and Epishine which resulted in a sensor that is powered solely by indoor solar cells as well as an enclosure made from biodegradable materials.

”ELSYS has taken sustainability to a new level within IoT and building automation sensors with the new ERS Eco sensor line. We are proud to be their partner, supplying our light energy harvesting modules. Epishine’s organic solar cells are perfectly optimized for the ERS Eco sensors with their market-leading performance in indoor light conditions.” says Jonas Palmér, Sales and Business Development at Epishine.

Sensors powered with Epishine’s indoor light energy harvesting modules do not only function uninterrupted when ambient light is available but also function continuously for up to seven days in the dark. This results in a solution with very low or no maintenance and with no need to ever change batteries again.

“This combination of energy harvesting from indoor light, battery-free operation, and a biodegradable enclosure is an IoT industry first. I believe that we at ELSYS, with ongoing support from Epishine, have developed a truly unique and ground-breaking product.” says David Skånehult, Hardware Engineer at ELSYS.

X-Sense XP01-W Smoke and Carbon Monoxide Alarm Detector with Up To 10-Year Battery

Posted on by Abhishek Jadhav

Introduction

Almost all North American houses come with fire and smoke detector alarms, however, with poor maintenance, this product can defy the purpose. Here comes the combination of smoke and carbon monoxide detectors inside a compact consumer product, ready to be deployed in the home environment becoming an essential part of our life. The production of such alarm detectors has been on the rise from various manufacturers competing with almost the same functionalities but with minor tweaks and upgrades. Today, we will be reviewing the X-Sense XP01-W smoke and CO alarm detector with a large silence button that is currently available on Amazon for sale at $107.99 (3-pack).

Two-in-one function

When we hear about smoke and CO alarm detectors, there are several functionalities that we look for reasonable price points and the requirements can vary depending on the budget and type of deployment. X-Sense has been in the market for designing consumer-facing integrated solutions, like detectors for home safety, and these products range from smart home security systems, smoke detectors, CO detectors, and the combination of the two.

Sensor Introduction

As the article focuses on their top-selling X-Sense XP01-W smoke and CO alarm detector, the consumer product will be equipped with both photoelectric and electrochemical carbon monoxide sensors that work independently of each other and notifies when dangerous smoke or CO concentration is detected.

X-Sense XP01 Alarm Detector Breakdown

Package Contents

  • 3 × Alarm Unit
  • 3 × Mounting Bracket
  • 9 × Screws
  • 9 × Anchor Plugs
  • 1 × User Manual

10-year battery

Often, cheap products can give a false alarm for detecting steam’, but it is important for the alarm detector to minimize false alarms and provide improved performance for protection from two deadly threats. The X-Sense XP01-W provides high accuracy and reliability along with high sensitivity and upgraded battery life. Featuring a built-in 10-year battery provides continuous power through the Lithium battery and saves energy while maintaining the eco-friendly mode. This time of the year, the fire department issues notice for residents to change the battery in the alarm detectors before Day Light Savings Time, but with 10-year battery life, the customers can consider shifting from the traditional alarm detectors to the highly efficient XP01 alarm detector.

Technical Details

Interconnection Function

Sized at 5.3×5.3×1.7 inches, the alarm detector is smaller than the X-Sense SC01 and that is for obvious reasons. The XP01 detector does not come with an LCD display, like the Wireless Interconnected Combination Smoke and Carbon Monoxide Detector we reviewed earlier, saving the space on the hardware while providing an easy silence button on the front of the device which is easy to push either by hand or a broom handle. Another downside for the XP01-W detector is the inability to connect to the internet and hence cannot be integrated with a smart home system. Also, the hardware does not come with a human-voice detection system to control the functionalities and settings. Since the chipset does not support wireless connectivity, it cannot wirelessly communicate with the Phone to monitor the gas concentration in the room.

Conclusion

Reasonably priced at ~$37 per unit, the XP01-W alarm detector is not expected to provide as many features as the highly advanced alarm detectors from Google (Nest). For the price range, the product seems to offer enough functionalities for a normal home use case where the operator is not concerned with its wireless connectivity and smart integration. Through an easy installation process, the shipped package will contain a mounting bracket, screws, anchor plugs, and a user manual for the alarm unit. You are encouraged to purchase the product on Amazon and let us know about your experience.
