Introduction

MPM426WS Deep-water Level&Temperature Transmitter is a full welded, full sealed and submersible diffusion silicon instrument for level and temperature measurement. It uses a high stable and reliable piezo-resistive OEM pressure sensor and a PT1000 temperature sensor with a high-performance signal processing circuit mounted in stainless steel housing. Meanwhile, the product adopts double-way sealing with special rubber rings and the sealing and locking line 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 measurement of oil and gas in 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.

Notes:

1. Please be sure the measured media is compatible with contacting material; please also note the media density in the measurement (except water);

2. We provide two kinds of cables --PVC and polyurethane for option, charged based on materials and length.

3. If the product is installed in “lightning and thunder” area, we suggest to use lightning-proof protection device to protect transmitter. Please be sure good grounding as well;

4. Under standard conditions 1mH2O (4℃, g=9.80665 m/s2), the corresponding relationship between 1mH2O and pressure is showed as follows: 1mH2O = 0.1kgf/cm2 = 9.80665kPa;

5. If the user has special requirement, please feel free to contact our company.
