Multi-functional Intelligent Differential Pressure Transmitting Controller

MDM460 differential pressure controller with local LED display, supports relay signal, analog or Modbus output. Maximum 5 controlling points.
MDM460 intelligent transmitting control could measure and control differential pressure accurately in rugged open environment. It can use RS485 netting and display local measure value, and provide analog standard signal or relay control signal. The product could be used for differential pressure measuring, transmitting, displaying and transforming of chemi-industry, metallurgy, ocean, aviation, measurement, science, etc.
