Product Description
QST204 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.
The QST-204 Submersible Level & Temperature Integration Transmitter is a high-quality solution for measuring the level and temperature of various liquids. It is composed of a high accuracy and stability pressure sensor, temperature sensor, and a special propose circuit. The measured media's level and temperature are transformed into a 4~20mA or 0 ~ 10mA electrical output signal separately.
This liquid level sensor offers high reliability and stability, making it suitable for measuring both static and dynamic states of liquids in water works, oil refineries, chemical plants, glassworks, and more. With its accurate and stable performance, it ensures precise monitoring and control of liquid levels and temperatures.
