DW808DP Micro differential pressure transmitter

DW808DP differential pressure transmitter is used to measure the level, density, pressure and flow rate of liquid, gas or steam, and then convert them into 4 ~ 20mADCHart current signal output. DW808DP can also communicate with RST375 handheld terminal or RSM100 Modem for parameter setting, process monitoring, etc.

DW808DP-R Differential pressure remote transmitter

DW808DP-R differential pressure remote transmitter is used to measure the level, density, pressure and flow of liquid, gas or steam, and then convert them into 4 ~ 20mADCHart current signal output. DW808DP-R can also communicate with RST375 handheld terminal or DWM100 Modem, through which parameter setting, process monitoring and so on can be carried out. The measurement range of DW808DP-R differential pressure remote transmitter (without transfer) is 0-1kPa ~ 2MPa, and the rated pressure of remote flange is 1.6/4MPa, 6.4MPa, 10MPa, 150psi, 300psi or 600psi respectively.

D398 Pressure test bar

The D398 pressure calibration stick provides the pressure source for calibrating the differential pressure, pressure gauge and differential pressure/pressure transmitter, and can also be used to set the setting value of the differential pressure/pressure switch. An additional standard pressure gauge is required. Can be fine-tune to produce a pressure of from a few tens of Pa to 5 bar.
