DTM.OCS with RS485 ModBus

Precision Pressure Transmitter DTM.OCS with RS485 ModBus

The DTM.OCS series pressure transmitters are polynomial compensated high performing pressure sensors which achieve total error bands up to 1.2%FS over a temperature range of -40 to 185°F.  The DTM.OCS are based on the standard RS485 ModBus protocol and can be easily connected to the control panel. In addition to the standard ModBus commands, specific commands were developed to take advantage of the full capabilities of the DTM.OCS. For example the pressure units can be changed any time or an offset can be programmed onsite. In addition to measuring pressure this sensor also measures temperature.
