Microsensor Corp MPM426WS Temperature Transmitter

Microsensor Corp MPM426WS Temperature Transmitter is a fully welded, fully sealed, and submersible diffusion silicon instrument for level and temperature measurement. It uses a highly stable and reliable piezo-resistive OEM pressure sensor and a PT1000 temperature sensor with a high-performance signal processing circuit mounted in a stainless steel housing.

Meanwhile, the product adopts double-way sealing with special rubber rings and the sealing and locking lines are separated in order to improve the sealing degree. The cavity(the terminal is in it) is filled with high- vacuum water resistance and mineral oil resistance sealing silicone so that the leading-out terminal can be fully sealed and insulated.

It is especially suitable for the measurement of oil and gas in a deep well. The advanced production technology and automated production line ensure the stability of products, and good adaptation makes your device able to copy with various complex environments
