Honeywell 535-34AB08-203 Strap-On Pipe Sensor 20K Ohm

The Honeywell 535-34AB08-203 is a 20Kohm strap-on pipe sensor designed to precisely measure water temperature in HVAC systems, particularly compatible Honeywell thermostats. This sensor features a thermistor, a temperature-sensitive resistor, encased in a small metal probe. As the pipe temperature changes, the thermistor's resistance changes accordingly. The sensor transmits this resistance value to the thermostat, allowing for accurate temperature control. The 1.125-inch probe with a 0.188-inch diameter easily straps onto pipes for convenient installation. With a wide operating range of -40°C to 120°C and an accuracy of ±0.2°C, this sensor ensures optimal system performance. Benefits include precise temperature control, improved comfort, and potentially increased energy efficiency by optimizing boiler or chiller cycles based on accurate readings.
