Electrodeless Sensor resists fouling.
PEEK(TM) Sensor, for WEC electrodeless conductivity controller, measures accurately over wide dynamic range and handles applications from 50 Ã-µS to 1000 mS. Non-contacting toroidal sensor technology eliminates contamination and calibration issues, and is immune to thin coatings that would impair operation of direct contacting sensors. Sensor is suited for applications in metal finishing for...

Feed Sensor verifies flow of liquid through pumps.
PosiFlowO, suitable for EH and EZ Series pumps, detects flow of liquid output by pump, which verifies metering pump is moving liquid and has not lost prime. It does not incorporate any moving parts, and offers preserved flow path to eliminate plugging or jamming. Output signal stops if pump loses prime, is in dead-head condition, or if pump loses pressure due to broken discharge line. Input...
