ACI A/RH2-CP-D-BB : Duct Relative Humidity Sensor, 2% Accuracy, RH Outputs: 0-5, 0-10 VDC & 4-20mA (Default), 10K Ohm Thermistor (Type II), NEMA 3R Duct Enclosure, Made in USA

The ACI Relative Humidity with Thermistor Duct Series utilizes a thermoset polymer capacitive sensing element with a factory fitted hydrophobic filter to improve its moisture resistance. The sensing elements multilayer construction also provides excellent resistance in applications where dust, dirt, oils and common environmental chemicals are found. The RH duct sensors include on board DIP switches which allow the user to select the desired output signal and can be powered by AC or DC power sources. Each unit also contains 0%, 50%, and 100% test options to verify that the transmitter is both working and wired properly. Field calibration can be performed by using the increment and decrement calibration DIP switches without the need to replace the sensing element. These enhancements provide increased flexibility and outstanding long-term reliability without the need to replace the sensors in the field.

Applications:

Humidification
Dehumidification
Supply / Discharge / Return Air
Economizers
Clean Rooms
Data Centers
Process Control
Schools
Hospitals
Office Buildings
