Level control is used in applications where fluid is being moved, monitored, or otherwise included in the system. Crouzet level control relays work by taking input from two level sensors, such as ...

LONDEX, LTD., 207 Anerley Road, London, S.E.20, have introduced a patented system (“Lectralevel”) of floatless liquid level control, designed for automatically pumping out, filling or maintaining the ...

This reference design describes a cost-effective, low-power liquid-level measurement data acquisition system (DAS) that use a compensated silicon pressure sensor and a high-precision delta-sigma ADC.

Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.
