S+S REGELTECHNIK 1101-3132-0089-900

In commercial HVAC systems and building automation, monitoring the average (mean) temperature across a duct or along a rod length is vital for efficient climate control. The S+S Regeltechnik 1101-3132-0089-900 fills this need precisely. Its robust Pt1000 sensor element delivers high accuracy and stability, while the 4-20 mA output ensures integration with standard controllers or PLCs. With eight selectable measuring ranges via DIP switch, this unit adapts for a variety of installations—from cold air supply to hot exhaust ducts. The stainless steel shear-protected probe ensures long lifetime in demanding environments, and the IP65 rated housing resists dust and moisture when mounted in ventilation shafts. Compared to simpler sensors that only sample point temperature, this mean-value transducer integrates signals along its active length, offering more representative temperature data and eliminating hot or cold pockets. Use-cases include duct-mounted sensors in air-handling units, rod-mounted in large industrial halls, or continuous monitoring of return-air streams. For building managers seeking better energy control, reduced sensor drift and fewer maintenance cycle interruptions, this device stands out for reliability, accuracy and flexibility.
