Siemens Building Technology 544-089 Surface Mount Temperature Sensor 1K Ohm Platinum RTD

The Siemens 544-089 surface-mounted temperature sensor has a high precision of measuring pipe temperatures in air conditioning systems and building automation applications. This sensor uses a 1K Ohm platinum RTD element with a great resistance change due to temperature changes. The sensor is housed in a robust 2" x 4" aluminum box which is easily secured to pipes with nylon straps. The 544-089 provides dependable data for managing HVAC equipment, including boilers, chillers and fan coil units, and operates between -40°F and 240°F. Monitoring of pipe temperature makes possible HVAC systems that maximize comfort, energy economy and performance. This sensor provides the exact data needed to maintain optimum indoor conditions, save energy, and prevent equipment failures.
