Water Detectors

Small Sealed Water Detector Electronic control relay for detecting a rising water level, it has a medium power relay inside its waterproof enclosure, which operated by water reaching the trip level, and can be used to control alarms or other equipment  Specifications

 Converter

Voltage and Current Converter/Rescaler convert voltage signals in the range of 1-19V or current signals in the range of 1.33-76 mA into a 4-20 mA non-isolated signal. This current source signal can be direct or reverse acting and can be used to drive grounded 4-20 mA loads utilizing a single power supply.
