Siemens 544-578 Outdoor Air Temperature Sensor 1K Ohm Platinum RTD -40°F-240°F

The Siemens 544-578 sensor is precision engineered to monitor the outside air temperature properly. As a result of an implementation of a 16 bit A/D converter and a Resistance Temperature Detector for platinum construction, it is capable of deliver dependable operation over a wide stabilized range of 40°F to 150° F. Its 375A alpha value and 1000 Ohm resistance guarantees accurate temperature measurements. This sensor is essentialto the proper functioning of the HVAC system. This helps towards a more comfortable and more energy efficient system by letting the system 'adjust' on real time outdoor temperature data when needed. Because to its rugged construction and solid outlook, it may be used in a number of outdoor settings.
