ADPT-UP Differential Ultra-Low Air Pressure Transmitter W/LCD

Description

The Ultra Low Pressure Transmitter is used to measure differential pressure up to 1”wc or 250 Pa and transmit via Analog and BACnet® Communications (latter optional).
 

It combines precision high sensitivity silicon sensing capabilities and the latest ASIC technology to substantially reduce offset errors due to changes in temperature, stability to warm-up, long term instability and position sensitivity. It is ideal for monitoring pressure for air or other clean inert gas. It features bi-directional pressure measurement, an on-board auto-zero function, a backlight LCD to display the pressure value and an optional alarm relay with variable trip points. The device is field-configurable via the local menu or the BACnet® connection. A weatherproof Polycarbonate enclosure with a hinged and gasketed cover is provided for ease of installation.

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).
Please contact us if you require 60Pa Model,  Relay option or BACnet MS/TP versions.
