Humidity is one of those variables that quietly shapes how buildings, processes, and equipment behave. Too much moisture can invite a variety of issues, like corrosion, condensation, and mold. At the same time, too little humidity can cause a range of problems, including static, material shrinkage, and comfort issues. In most facilities, maintaining relative humidity within bounds depends on sensors that can be easily installed, retain calibration, and integrate cleanly with existing control systems.AutomationDirect has released its new ProSense HUM series of humidity sensors. Image used courtesy of AutomationDirectAutomationDirect has expanded its ProSense HUM series of humidity sensors to cover a range of mounting styles and applications, from HVAC ducts to cleanrooms and equipment enclosures. The ProSense HUM series was designed to focus on practical installation, wide temperature and humidity coverage, and familiar analog outputs, providing maintenance personnel and engineers with tools for monitoring both temperature and relative humidity across industrial and commercial environments.Single Platform; Multiple Mounting OptionsThe ProSense HUM lineup is meant to cover a wide range of installation scenarios without forcing engineers to jump between different sensor platforms. Duct-mount models place the sensing probe directly in the airflow, which works well for HVAC and ventilation systems in warehouses, agricultural buildings, and large facilities where air movement is consistent.The ProSense HUM series spans duct-, wall-, and room-mounted sensors to measure temperature and relative humidity across HVAC and industrial environments. Image used courtesy of AutomationDirectWall-mounted or duct-mounted versions offer enhanced flexibility, enabling the probe to navigate through ductwork or hang freely in open spaces commonly found in data centers or process rooms. Compact wall-mounted sensors are also available, providing a discreet option for ambient monitoring ideal for cleanrooms, server rooms, greenhouses, and laboratories where both space and aesthetics are important. Each sensor in the ProSense HUM series measures temperature and relative humidity, ranging from -4 to 140 °F (-19.9 to 60 °C) and 0.0 to 99.9% RH.Integration and Visibility.All ProSense HUM sensors provide industry-standard 4–20 mA outputs, simplifying connection to PLCs, building management systems, and data loggers. Select wall/duct models include a bright, two-line LED display that shows temperature and RH locally, which can be useful during commissioning or troubleshooting without opening software tools.The ProSense HUM sensor features probes in 100 mm and 200 mm lengths to support a variety of duct sizes and mounting depths, while IP65-rated housings help the sensors withstand dusty or damp environments. For applications that prefer resistance-temperature inputs, the HUM-R-PT room model provides a Pt100 temperature output alongside the humidity signal.Where Humidity Control Matters MostHumidity shows up in different ways depending on the environment. With HVAC systems, it’s about keeping occupants comfortable and machines within operating temperatures while avoiding moisture damage. However, inside cabinets and enclosures, the goal is to prevent condensation and corrosion before they reach sensitive electronics.In enclosures, humidity monitoring can keep corrosion under control while keeping sensitive electronics within safe operating conditions as environmental moisture shifts around them. Image used courtesy of AutomationDirectFor applications such as cleanrooms, curing processes, and moisture-sensitive storage areas, maintaining stable humidity is crucial to protect quality and consistency. At the same time, greenhouses and agricultural facilities use RH data to support plant health and limit disease. Data centers sit at the other end of the spectrum, where both excess moisture and overly dry air can create serious risks.Most of the time, humidity control only gets noticed when something goes wrong. By offering multiple mounting styles, wide temperature and RH ranges, and standard analog outputs in a single sensor family, the ProSense HUM lineup gives engineers a straightforward way to keep moisture under control without overcomplicating installation or the control strategy.
