DPTx Pressure Transmitter

Home / Products / Instrumentation / DPTx Pressure Transmitter

The DPTx Pressure Transmitter from Sensing Precision is ideal for the monitoring and management of ventilation systems and is the perfect compliment to the high end Wilson Flowgrids or Eco-Radial Flowgrids. There are two standard models. The DPTx-250, (±250Pa), and the DPTx-500, (±500Pa). All DPTx’s are equipped with industry standard 4-20mA and 0-10V outputs. Each output can be scaled against either pressure, velocity or flowrate, with a configurable range setting for each output.

What sets the DPTx apart from most other transmitters is the LCD Display which is fitted as standard, and the menu driven graphical user interface, which makes installation and commissioning easy and straightforward.

The DPTx range of pressure transmitters also offer a RS485 MODBUS interface, with a limited subset of instructions, that can be utilized to interface the transmitter to a BMS controller.
