Description
The Belimo 01DT-5LL 4” Duct/Immersion Sensor Temperature Passive is a sensing component used to monitor temperature levels within ductwork and fluid control assemblies in HVAC systems. This sensor uses a passive NTC10K sensing element that detects thermal variations and transmits four-inch temperature readings to connected control equipment to enable a regulated system response. The component is housed in air handling units, ventilation systems, chilled water assemblies, and heating equipment where stable temperature monitoring is necessary. The system manages controlled operating conditions, improves measurement accuracy, and eliminates interruptions caused by inconsistent thermal regulation or airflow imbalance.
