Air Pressure and Volume Transmitters - Displays and Alarms for industrial Ventilation Systems
The new DPM-110 Pressure Volume Transmitter
The DPM-110 has been launched successfully and has had substantial success. The instruments have been installed in quite a number of major projects in many countries in Europe. The main benefits for the users are :
Autozero facility... which means the sensor is always accurate even at very low pressure mesurement applications.
Measurement and also Control Output .... which means the DPM is capable of measuring pressure and air volume for monitoring purposes, but also a built in PID loop control to drive dampers and fans inverters.
Alarm Output... which means the DPM cam provide a high or low alarm relay output or an alarm and buzzer output with alarm mute input.
Door open Contact Input... which means If the alarm mute facility is not used the inoput can be configured to be a door contact input in order to freeze the PID control loop if the DPM is used for toom pressure control.
Remote Display of Pressure and Alarm.. which means a CMR remote display plate can be fitted to an independent Modbus communication port on the DPM and the actual value is displayed identically on the plate as on the DPM as it is transferred digitally. A remote alarm mute button is also provided on the display plate.
Modbus rtu Communication... which means the Modbus rtu network communication can be connected to any external control or monitoring system and yet still provide local alarms and control outputs. All set points and mute can be controlled from the central computer system.
The DPM-110 can be supplied with a linearity of 0.2% and it comes complete with a UKAS traceable calibration certificate as all other CMR transmitters,
Main Features in short
Auto zero Overload protection Dual output 0..10V - 4..20mA Modbus rtu communication for Central Computer Independent remote display modbus rtu connection Alarm function with buzzer and mute on remote Two output relays One signal output can be switched to PID control One signal output can be used for monitoring Complete Modbus protocol control Interface to any PLC or BMS
It is almost like a complete outstation with a built in pressure or volume transducer
