The UDS-4 level transmitter is the full stainless steel construction and full-sealed submersible intelligent level transmitter with high accuracy.

It uses highly reliable and stable pressure sensor, intelligent processing circuit, precise digital temperature compensation and linearity correction technics for production.

The water-proof cable connects sealed to the housing, with a vented tube inside the cable, the transmitter could be used in the water or liquid for a long time. Integrated construction and standard output signal could provide easy operation and good automatic control. The transmitter is a 2 wire 4-20 mA sensor with parallel RS485. The 4-20 mA can also be based on the HART protocol.

The transmitter is standard fitted with a PUR cable with integrated vented tube for air pressure change compensation. This makes the UDS-4 an ideal liquid level measuring device.
