ZMD AG is sampling a new signal-conditioning chip based on a capacitive-sensor architecture for very low current draw. The ZMD31210 cLite device offers 14 bits of resolution with 0.5 percent accuracy ...

Dresden, Germany – ZMD AG has added the ZMD31210 cLite IC to its family of capacitive sensor signal conditioning devices. Capacitive sensors offer several benefits, including very low power operation, ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Paul Whytock reports on integrated converters that tackle the signal-processing challenges of direct capacitance-to-digital and impedance-to-digital conversion. The world's first high-precision, ...
