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.

| 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.
