Microsensorcorp MPM489WZ3 Submersible Level Transmitter


Microsensorcorp MPM489WZ3 Submersible Level Transmitter uses a high-performance pressure sensor as a sensing element, It could measure liquid static pressure that is positively proportional to level depth precisely, and transform pressure signal into standard current/voltage signal output by amplifier circuit to measure accurate level depth.

The product has high accuracy, compact size, easy installation, can be submersible into the liquid directly to measure level and media temperature from transmitter bottom to the liquid surface. It can be widely used for water and other liquid level measurement and control in fields of petroleum, chemical industry, power station, city water supply, and drainage and hydrology, etc

  • Please be sure the measured media is compatible with contacting material; please pay attention to media density in the measurement (except water);
  • If the output signal is a voltage signal, if you want to receive the temperature signal, select “T” in the product specification.
  • If the product is installed in the “lightning and thunder” area, please note “lightning-proof” in the order. We suggest installing a Lightning-proof Protection Device to protect the transmitter. Please be sure good grounding as well;
  • If the user has a special requirement, please feel free to contact our
