Siemens QAE2164.010 Immersion Temperature Sensor – 0–10 V DC Output, 100 mm Probe, −10 to +120°C

General
The Siemens QAE2164.010 is an active immersion temperature sensor designed to measure liquid temperatures in heating, ventilation and air-conditioning (HVAC) systems. It is suitable for monitoring and controlling flow temperatures in pipes and tanks.

The sensor converts the temperature measured by its sensing element into a 0–10 V DC output signal for connection to compatible controllers and building management systems. It features a 100 mm stainless-steel immersion probe and is designed for reliable temperature monitoring in water-based HVAC applications.
