DPT-R8 Differential Pressure Transmitter

Quick Overview

The DPT-R8 is an electronic differential pressure transmitter with eight jumper selectable measurement ranges in one device, from +/-100PA up to 0-7000Pa. The output is selectable as 4-20mA or 0-10V. The units also have the option of an LCD or Auto Zero function.

Selectable Pressure Ranges

Model 2500	Model 7000
-100 to +100 Pa	0 to 1000 Pa
0 to 100 Pa	0 to 1500 Pa
0 to 250 Pa	0 to 2000 Pa
0 to 500 Pa	0 to 2500 Pa
0 to 1000 Pa	0 to 3000 Pa
0 to 1500 Pa	0 to 4000 Pa
0 to 2000 Pa	0 to 5000 Pa
0 to 2500 Pa	0 to 7000 Pa

Auto Zero Element

The optional auto zero element allows the transmitter to perform as a maintenance free unit. The element automatically adjusts the transmitters zero point from time to time, this eliminates the zero point long term drift of the piezoresistive sensing element. Units without an Auto Zero Element will require a manual zeroing at least every 12 months.
