ACI A/RH3-D-BB : Duct Relative Humidity Sensor, 3% Accuracy, RH Outputs: 0-5, 0-10 VDC & 4-20mA (Default), NEMA 3R Duct Enclosure, Made in USA
Maintaining optimal humidity levels in your building's ductwork is crucial for efficient operation, occupant comfort, and even protecting sensitive equipment. That's where duct humidity sensors come in. These sensors play a vital role in monitoring and controlling humidity within your HVAC system, offering numerous benefits:
- Precise Measurements: Duct humidity sensors, like the ACI A/RH3-D-BB, utilize advanced capacitive sensing elements to deliver accurate humidity readingswith 2% accuracy. This ensures you have the right data to make informed decisions about your system's operation.
- Enhanced Durability: Built with a weatherproof enclosure and multilayer sensing elements, these sensors offer superior resistance to dust, dirt, oils, and common environmental contaminants, making them ideal for demanding environments.
- Versatile Applications: Duct humidity sensors have a wide range of applications, including humidification/dehumidification control, monitoring supply/discharge/return air, optimizing economizer performance, and maintaining precise humidity levels in critical environments like clean rooms and data centers.
- Easy Installation and Maintenance: The ACI A/RH3-D-BB features on-board DIP switches for selecting the desired output signal and field calibration capabilities, simplifying installation and maintenance. Additionally, the conformally coated circuit boards provide further protection against moisture.
By incorporating duct humidity sensors into your HVAC system, you can gain greater control over humidity levels, leading to improved efficiency, occupant comfort, equipment protection, and overall system performance.
