MPM4881 pressure transmitting controller applies in the hydropower speed generating system. The pressure control and automatic air make-up of the oil hydraulic system can be realized independently for its stability and reliability, which helps develop the system self-protection ability, therefore, improve the hydropower automation degree and economic benefits.

Both the analog and switch signal outputs from MPM4881 pressure transmitting controller can input relative PLC. This offers important basics for the automatic system control governor system and moreover, provides parameters for automatic and manual adjustment of the LCU system.

LCU application

MPM4881 pressure transmitting controller has a terminal protection cover or water-proof connector for dust-proof and short circuit functions.

4881 applications

MDM4881 differential pressure transmitting controller applies in hydropower station input water main valve for differential pressure detection and control.

So far, the pressure sensor, pressure transmitter and pressure transmitting controller we designed and manufactured have been applied successfully in hundreds of hydropower governor systems.
