Submersible Hydrostatic Level Transmitters

MJK Expert™ hydrostatic level transmitters are designed for level measurement by submerging the transmitter in open channels, drains and tanks.

Expert™ hydrostatic level transmitters have a modern design with high functionality and the use of modern plastic and steel materials. MJK level transmitters are used in sewage plants, pump stations, waterworks and and in process tanks in the industry.

For more than 20 years MJK level transmitters have had a reputation for their high accuracy and stability, the ability to withstand rough industrial environments, their sturdiness and functional design and wide measuring ranges. The Expert™ Level Transmitter Model 1400 and 3400 are approved according to UL and Atex for applications in hazardous areas.
