MPM489P Flush Diaphram Pressure Transducers

Brief Introduction

The MPM489 product is a flush diaphram piezo-resistive pressure transmitter. It uses a highly stable and reliable pressure sensor and special electronics to produce the transmitter, and the performance is good and reliable.
The MPM489P pressure transmitter is used for the measurement and control of petroleum, chemical industries, electric power, hydrology, irrigation and flow pressure measurements, especially in situations where there is risk of solids clogging the traditional Pressure Transducer cavity.
