Belimo 01DT-5EP Duct / Immersion Temperature Sensor – Passive Ni1000 (JCI), 8-In Probe
Overview
The Belimo 01DT-5EP is a passive duct/immersion temperature sensor (Ni1000, JCI) designed for HVAC and fluid systems. With an 8-inch probe (200 mm) and durable enclosure, the sensor is suited for measuring air in ducts or liquids via immersion (with thermowell). Comes with mounting clip, screws, adhesive foil, and conduit adapter. Accurate, reliable, and built for harsh environments.
