Product Description
Temperature and Level Sensor / Transducer / Transmitter (QST-204)

QST-204 submersible level & temperature integration transmitter in composed by high accuracy & stability pressure sensor, temperature sensor and special propose circuit, the level and temperature of measured media will be transformed to 4~20mA or 0 ~ 10mA electrical output signal separately. With the characteristics of high reliability and high stability, it is widely used for measuring static and dynamic state of various liquid in water works, oil refinery, chemical plant, glassworks, sewage treatment works, water supply system, reservoir and riverway.
Submersible temperature level transmitter
