Microsensorcorp MPM489WZ1 Level Transmitter

Microsensorcorp MPM489WZ1 Level Transmitter is a Φ19mm diameter fully sealed submersible level transmitter based on the diffused-silicone principle. It consists of a highly stable and reliable piezoresistive pressure sensing element and the special PCB component as well as the stainless steel housing.

Its integrated construction and standardized signal output greatly facilitate the operation and automation control at work sites. The special vented cable being hermetically connected with the transmitter housing allows the transmitter for long term use in the liquids that are compatible with the transmitter construction material.

MPM489WZ1 Level Transmitter is with compact size, lightweight and good long term stability. It is suitable for liquid level measurement and control for fields of medicine, metallurgy, power plants, mining, urban water supply and drainage, hydrology exploration, etc
