The sensors are housed in robust […]
Specialized sensors perform in extreme environments
Sensors withstand extreme temperatures, pressures and aggressive chemicals By Will Meenan, Kaman Precision Products / Measuring It takes an extremely durable design to make reliable measurements in extreme conditions. Extreme environment position/displacement sensors perform where most sensors cannot survive. These sensors are designed to operate in the following environmental conditions: High or cryogenic temperatures Aggressive […]
Capacitive sensors for OEM applications
A bandwidth of up to 20kHz enables the new capaNCDT 6112 controller to reliably monitor fast processes. A compact design and user-friendly handling make the controller suitable for measuring displacement, distance and position in a diverse range of applications, from test cells to highly automated environments and is therefore ideal for OEMs and high volume […]
High-performance MEMS capacitive accelerometers feature improved temperature performance, scale factor and bias temperature shifts
Silicon Designs Inc. has announced the global market introduction of six new series of low-cost, high-performance MEMS capacitive accelerometers, in both traditional and smaller footprints. These include the single axis Model 2220 or triaxial Model 2470, featuring aluminum housings and a standard 1 meter integral cable; the single axis Model 2240 or triaxial Model 2480, featuring […]
Digital Controller for High Precision Capacitive Sensing
To simplify the use of its pioneering capacitive sensors and provide precise positional feedback in closed loop applications, Queensgate developed its NPC-D-5200 digital controller. The controller incorporates a precision capacitive measurement circuit that is updated with the stage position 120,000 times per second. This allows it to deliver high positional accuracy at speed. The controller/sensor […]
Measuring at the Nanoscale
Sometimes measurements have to be made at the smallest levels. Queensgate’s NX NanoSensor has the sensitivity to measure changes in position to an atomic scale. Key applications include: stage feedback, vibration measurement, metrology, deformation measurements, precision manufacturing, drift measurement, precision beam steering and microscopy. The non-contact position measuring system consists of two sensor plates – […]
MEMS-Based Pressure Sensor Uses Thermal Differential for Sensing
Designed for VAV damper control as well as HVAC applications such as room pressure monitoring, fume hood controls, furnace press switches, heat recovery systems, burner control, fan control, filter monitoring and more, the MDP200 Pressure Sensor from MEMSIC Inc. is an integrated MEMS thermal differential pressure sensor. The sensor utilizes thermopile structures similar to the […]
The evolution of liquid level sensing
by Matt Burns, Technical Marketing Director, Sensors, Avnet There are multiple ways for engineers to measure and keep track of liquids in a container, and one will fit your application. Anyone who lives near a river or creek knows the anxiety that can happen during a thunderstorm, when rising water levels can cause high stress […]
Implement Proximity and Touch Sensing Technology without Writing any Software
Replacing a mechanical switch with a digital output touch sensor is a lot easier if the system designer does not have to write any code. With that goal in mind, Microchip Technology developed its MTCH102-5-8 capacitive touch controllers. The 2-, 5- and 8-channel controllers replace mechanical buttons with a simple digital output in a hardware-only […]
Noise-Immune Capacitive Sensing
Electrical noise source such as radios, power supplies, lights and motors can pose serious problems for capacitive sensors. To combat these problems, Texas Instruments (TI) FDC2214 capacitive sensing integrated circuit (IC) family offers 60x better performance in the presence of noise compared to existing capacitive-sensing solutions. The IC’s have a unique narrow-band architecture that eliminates […]
