MAMAC Systems HU-921-VDC-8 Humidity & Temperature Sensor 10K Ohm NTC 3% RH

The MAMAC Systems HU-921-VDC-8 Humidity Sensor is a unit-mounted part designed to measure relative humidity with integrated temperature compensation for precise environmental control in air handling system. It uses a 10K Ohm NTC thermistor for temperature sensing, and delivers stable humidity response with approximately 3% RH accuracy, making it suitable for economizer and building automation applications in HVAC systems. It is installed in air handling units rooftop, or ductwork where it continuously monitors moisture levels to support proper dehumidification control. By sending signals to the controller, it helps maintain stable indoor comfort conditions prevent excessive humidity, and improve overall system efficiency.
