Thermistor Level/Leak Sensors
Very small type thermal dispersion level sensors leak detectors Standard rubber grommet fitting commercial applications Leak detection package detect leaks Estel sensor material suitable water most oils
Polysulphone sensor material option acids alkalines powered Standard open collector transistor output High level switching optional- Solid state relay power transistor
series utilizes thermal dispersion principle dissipation heat liquid detect presence absence liquid compared with air. sensor contains resistor form thermistor. thermistor acts heater when voltage applied would resistor. also detects heat converts heat into electrical signal. When heat generated thermistor dissipated liquid, switch output occurs. designed meet standards major food health agencies around world. conforms Japan Food Research Laboratories standards, authorized Japan Ministry Health Welfare standards USA. approved components used construction sensor. Specific approval sensor available request.
