Hydrostatic Level Transmitter with Two-wired Analog for Industry
1. Introduction
ML2000T series static liquid level transmitter adopts imported silicon pressure transducer as sensitive element, utilizing reasonable industry structure to finish stainless steel sealing package. The amplifying circuit can ensure measurement accuracy through laser compensation . The electrical connection cable applies is anti corrosive gas shielded cable which makes the back pressure chamber is directly connected to the atmosphere.
