Microsensorcorp MPM416WK Submersible Level Transmitter

Microsensorcorp MPM416WK Submersible Level Transmitters use high-performance piezoresistive pressure sensors as sensing elements. It measures liquid static pressure accurately which is positively proportional to liquid depth, transmitting pressure signal into standard current/voltage output signal by the amplifier circuit board.

The product has high accuracy, compact size, and easy operation characteristics, and it can be submersible into the liquid to measure the level from the transmitter bottom to the liquid surface. It is widely used for the liquid measure and control of both petroleum, chemical industry, power station, city water supply, and drainage and hydrology.

Microsensorcorp MPM416WK Features

  • Separate construction; full sealed stainless steel construction for submersible/inserted sensor; aluminum-alloy electric connection box; easy for installation, wiring, and calibration;

  1. Please pay attention if the media is compatible with contacting material, especially pay attention to media density at measuring situation (except water);
  2. We provide the user with PVC or polyurethane cable; polyurethane cable is more flexible and wearable. If the user has no special requirements, the default would be PVC cable;
  3. If the product is installed in a lightning and thunder area, please note “lightning Protection” in the order; we suggest to use a lightning protection device to make sure power is grounding safely;
  4. When MPM416WK transmitter’s armored tube more than 2m, we would provide the user with a divided steel tube to help Please install tubes in local places; 5.If the user has a special requirement, please feel free to contact with our company.
