LU-924M memory type intelligent controller is specially designed to connect with liquid level,pressure and temperature sensor and transmitter to constitute all kinds of measuring range and specification measuring control system for liquid level,pressure,temperature,etc..

 

It can transform out standard analogue signals,and the transform data source,transform type and transform range can be set freely.

 

The display adopts double four bright LED numerical code tube plus 20 segments light pillar which corresponds to percentage of transform output or measured value.
