Introduction

MTM4881 Temperature Transmitting Controller is an intelligent meter integrating temperature 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. Whole product protection is IP65.

MTM4881 Temperature Transmitting Controller provides 4-relay output + 1 analog output, which is applied in liquid medium’s temperature measurement, especially suitable for detection of oil temperature of hydraulic and lubrication transmission system.
