About Series DPT Range Differential Pressure Transmitter

Series DPT Selectable Range Differential Pressure Transmitter

The Series DPT Multi-Range Differential Pressure Transmitter was designed specifically for the building automation and HVAC industry. With field selectable ranges down to 0.1 inches w.c., this product is ideal for monitoring building pressure, static pressure, differential pressure, or air velocity and flow. The Series DPT Differential Pressure Transmitter also has jumper selectable outputs for 4-20 mA or 0-10 V and unit selection giving additional flexibility. For a virtually maintenance free transmitter, order the optional automatic zero and the transmitter will perform its own zero point maintenance. The Multi-Range Differential Pressure Transmitter also has an optional backlit LCD for giving local indication.
