Room Pressure Monitor / Transmitter KRPC Series

Room Pressure Monitor / Transmitter

 

The Kele KRPC Series room pressure monitor is used to measure differential pressure in the range of ±0.125″ to 1″WC or ±30 to 250 Pa. 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 warmup, long term instability and position sensitivity. It is ideal for monitoring pressure for air or other clean inert gas. It features field selectable bi-directional pressure ranges and output signal types for the most flexible application. The device has an on-board auto-zero function, backlit LCD and alarm function with silence switch.
