Introduction

MPM4881W Level Transmitting Controller is an intelligent meter integrating level measurement, display, transmitting and control. It adopts the internationally advanced ARM processing chip. By compensation and adjustment of the sensor, the product can achieve precise measurement and provide quick response and control of multiple relay. The meter supports peak record and action delay, providing 4 digit LED indicator, easy for reading. And the design of 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. The controller body protection level is IP65.The probe protection level is IP68.

MPM4881W Level Transmitting Controller provides 5-relay output + 1 analog output, which applies to the equipment automatic pressure detection, action control and water level alarm, is available for long-distance pressure measurement and control.

Notes

1.Please pay attention that the media should be compatible with the contacting parts; please inform the density of the media (except water);

2.Two kinds of cable are optional, polyurethane and polyethylene. The default is polyethylene. Polyurethane cable is more flexible and endurable; it can be selected due to the requirement;

3. If the user has special requirement, please feel free to contact us.
