Model:ADPT-ULP2B

Description

The ULP Ultra Low Pressure Transmitter is used to measure differential pressure in the ranges of 0.125″W.C. to 1″W.C. (30 to 250 Pa). It combines precision high sensitivity silicon sensing capabilities and the latest ASIC technology with Dynamic Self Compensation to substantially reduce offset errors due to changes in temperature, stability to warmup, long term instability and position sensitivity. It is ideal for monitoring pressure for air and other clean inert gas and is limited only to those media which will not attack silicon, nylon and epoxy adhesive.

The ULP features a selectable uni- or bi-directional pressure range and output signal types for the most flexible applications. An optional on-board relay output, which is field adjustable, allows for an alarm function as well as an LCD (Alarm relay and LCD are standard on BACnet model).


The ADPT-ULP2B includes an LCD display for Pressure readout.
