Siemens Building Technology 544-342-16 Temperature Sensor 319825-402 The 120V spring return actuatorThe Siemens 544 342 16 is a professional grade flexible averaging duct temperature sensor designed for accurate thermal monitoring in large scale HVAC air handlers and supply ducts. Engineered with a 16 foot flexible probe, this sensor mitigates the effects of temperature stratification by providing a true average reading across the entire duct cross section. Utilizing a high precision 1k Ohm Platinum RTD (375 alpha) sensing element, it delivers a
