Sensors
Pressure switch detects lowest gas pressures & liquid levels
Pewatron has announced the 901XL pressure switch for the lowest pressure and liquid levels. Wherever marginal gas pressures or liquid levels have to be determined quickly and positively, purely mechanical, membrane-controlled pressure switches are an economical sensing and switching solution.
Sensor optimised for assembly processes for mass production
A manufacturer of innovative thermal sensors for the surveillance, thermography, firefighting, outdoor leisure and automotive markets, ULIS, has announced the availability of Micro80 Gen2, an advanced functionality thermal sensor.
Accelerometers offer 10kHz frequency response on all three axes
PCB Piezotronics has announced a new design of triaxial accelerometer which offers frequency response of 10kHz on all three axes (competitive products typically offer upper frequency response from 5 to 8kHz but often have different responses on one of the three axes). Model 356A45 accelerometers also feature 100mV/g sensitivity with measurement range of ±50gPK and are housed in a titanium package measuring just 10.2x10.2x10.2mm.
New circuit uses BiCMOS technology
ASIC specialist Creative Chips from Bingen, Germany has extended its portfolio of ASSPs with an existing ASIC product that has seen further development in the new transimpedance preamplifier CCG1401 for use in optical sensor applications. This circuit uses a proven BiCMOS technology and achieves excellent noise characteristics.
NDIR gas sensors detect refrigerants safely & precisely
Pewatron has announced the smartMODUL BASIC EVO series of NDIR gas sensors. Gas sensors based on non-dispersive infrared (NDIR) absorption offer decisive advantages compared with electrochemical and catalytic sensors. The sensor principle exploits the quality of gases and absorbs infrared radiation at a specific, characteristic wavelength.
Gauge pressure sensors offer very low noise output
PEWATRON has launched the A3 series of gauge pressure sensors from Fujikura. The AG3 and AP3 series are compatible in footprint and pin configuration with the highly successful F and X series, but with better total accuracy performance (less than ±1.5%) and a very low noise output. The analogue AG3 & AP3 series is a two-chip system consisting of a MEMS sensor chip and a signal-conditioning chip.
Customised zirconia O₂ sensor modules cover ppm up to 95%
Pewatron has announced customised zirconia oxygen sensor modules and accessories for measuring ranges from ppm up to 95%. Pewatron's customisation allows the customer to put together the best suited oxygen module for any particular application. The oxygen sensors cannot be changed in form, fit or function, but the 4 sensor types (FCX-ULL, UL, UC and UWC) cover almost the full range of oxygen concentration ranges and can also work as humidity sens...
Linear hall effect sensors function as short stroke actuators in high-vibration environments
PEWATRON has announced MIDORI’s new LP-10HA small range of linear hall effect sensors. The models are especially suited for short stroke actuators in an environment with high vibration and dither movements. A broad temperature range of -40 up to +100°C makes them well suited for mobile applications.
Analysing facial expressions to detect driver distraction
The Signal Processing Laboratory 5 (LTS5) group of researchers at EPFL have developed a system to detect the cognitive distraction of car drivers, by analysing their facial expressions.
Small sensors utilise Wirepas Connectivity
Haltian’s IoT platform expanded with small sensors. Consisting of the Thingsee gateway, the platform also entails the Thingsee POD and TAG sensors. The sensors can be used for tracking and monitoring assets, goods and people in a completely new, and a far more cost-effective manner. The Thingsee router delivers the data collected from the sensors directly to the client’s back-end systems via a mobile connection.
