DPT-R8
DIFFERENTIAL PRESSURE TRANSMITTER
THREE-WIRE
DPT-R8 The DPT-R8 series includes electronic differential pressure transmitters that offer exceptional performance, high quality and competitive pricing. Because of the high accuracy of the devices, it is usually not necessary to narrow down the range to get precise measurements. DPT-R8 devices are easily customizable, and also available for private labelling.
USAGE & APPLICATIONS
The differential pressure transmitter is used for measuring low pressures of air and non-combustible gases in order to monitor and control building automation, HVAC and cleanroom systems.
