Sick of Hertfordshire has introduced a vibration, shock and temperature monitor for measuring signs of approaching machine failure. The harsh environment MPB10 Multi-Physics Box bolts on to industrial machines, including electric motors, pumps, fans and conveyor systems. “The MPB10 provides service data to enable predictive maintenance practices that can improve plant availability, maximise operating life, protect product quality and protect process ...

Melexis has unveiled what it claims is “the most accurate automotive pressure sensor ever made”. Intended for automotive engine management, the mems-based devices measure absolute pressure across 1 to 4bar. MLX90824 delivers a SENT protocol digital output MLX90822 has an analogue voltage output voltage “An accuracy of +/-0.5% of full scale is maintained over the course of the sensor’s working ...

NewTek Sensor Solutions of New Jersey is offering hermetically-sealed LVDT position sensors with a 4 – 20mA current loop output. “Sustaining accuracy with no errors over long distance transmissions, 4 – 20mA current does not degrade over long connections and is less sensitive to background electrical noise,” according to the company. “Simple to connect and configure, the 4-20 mA output ...

Texas instruments has introduced a precision bi-directional current sense amplifier than can measure voltage drops across shunt resistors over a common-mode range of -5 to 110V, with survival across -20 to +120V. Bias current is 35µA within the operating range, and that operating range is independent of the 2.7 to 20V single rail supply voltage, from which 2.5mA is drawn. ...

Infineon has introduced an automotive current sensor IC, available in four pre-programmed current ranges: 25, 50, 75 or 120A. Called TLE4971, they are “ideal for on-board chargers, high-voltage auxiliary drives and charging applications”, according to the company. “Additionally, the sensor is also ideal for industrial applications including dc chargers for electric vehicles, industrial drives, servo drives and photovoltaic inverters.” Inside, ...

ScioSense has launced a family of digital temperature and humidity sensors with accuracies down to 0.1°C and 0.8% relative humidity. ENS21x sensors (see below) are aimed at home appliances, building air conditioning, automotive air conditioning, cold chain management, health monitoring, industrial automation and instrumentation. Response can be in under a second for temperature and three seconds for humidity. Stand-by consumption ...

Flusso has launched an evaluation kit for its forthcoming 3.5 x 3.5mm FLS122 flow sensor. The kit is plug and play, with the sensor on a small PCB that connects to a host PC, and associated software for the PC. The sensor module is configured and calibrated via an I2C cable. FLS122, announced in May, is claimed by Flusso to ...

Infineon will be revealing two internet-connected sensor evaluation kits at the Electronica exhibition in Munich, one for 60GHz radar and one for CO2 sensing. The company has made the sensor board part of these kits compatible with AdaFruit’s ‘Wing’ format which plugs into processor boards with AdaFruit’s ‘Feather’ pin layout. Infineon has adopted the Wing format for a planned series ...

CUI Devices has announced two MEMS microphones designed for active noise cancellation. CMM-2718AB-3815NC-TR (right) and CMM-2718AT-3817NC-TR (left) are omni-directional analogue microphones with bottom or top sonic ports, respectively. “Thanks to their flat frequency response from 20 to 10,000Hz, signal-to-noise ratios of 62 or 64dBA and acoustic overload points of 123 or 128dBspl, these microphones are ideal for use in active ...

Honeywell has created a tough six-degrees-of-freedom inertial measurement unit for heavy-duty and off-road vehicle applications. TARS-IMU, as it is called, comes in two versions: 5V or 9 – 36V, and includes a sensor-fusion algorithm. “The sensor fusion algorithm can be customised for specific vehicle applications via on-board firmware, allowing movement data to be filtered to minimise unwanted noise and vibrations,” ...
