Product information "Belimo 01DT-1LP NTC10k Duct/Immersion Temperature Sensor (200 mm)"

The Belimo 01DT-1LP is a passive temperature sensor for accurate temperature measurement in air ducts and, when used with a suitable thermowell, also for pipe (water) applications. It uses an NTC10k (10k2) sensing element and a 200 mm stainless-steel probe (Ø6 mm), making it well suited for AHU duct temperature monitoring and water temperature measurement in HVAC control systems.

The sensor is built in a rugged IP65 / NEMA 4X rated housing and is supplied with a mounting clip and fixing accessories for duct installation

Applications

AHU / duct supply air temperature sensing (post-coil or discharge air monitoring)
Return air / mixed air temperature sensing in HVAC ducts
Pipe immersion temperature sensing (with thermowell) for chilled/hot water loops, AHU coil circuits, and general HVAC hydronic measurement
