Introduction

MPM4881 Pressure Transmitting Controller is a digital meter integrating pressure measurement, display, transmitting and control. It adopts the internationally advanced ARM processing chip. By compensation and adjustment of the sensor, this pressure transmitting controller can achieve precise measurement, quick response & control of multiple relays. The controller supports peak value record and action delay, providing 4 digit LED display, easy for reading. Multiple buttons makes the operation easier and more convenient. Either current or voltage output signal is optional. It supports back mounting, rail mounting, cover mounting and joint mounting. Whole product protection is IP65.

MPM4881 pressure transmitting controller supports 5-relay + 1-analog output. It can be applied for long distance pressure measurement and control in the equipment automatic pressure detection, action control and water level alarm etc. It is also a preferred choice for working fields where request high frequency / high accuracy switchover or mechanical pressure relays is incompetent.
