Siemens QAC22 Outdoor Temperature Sensor Ni RTD 1k Ohm 32°F, −58°F to 158°F Terminal Block, No Display

The Siemens QAC22 Outdoor Air Sensor is a quality and efficient device for measuring outdoor air temperature in HVAC systems. This sensor is made of plastic material and it can measure temperature from -22°F to 122°F, which is a ideal for any climate. The output is an analog signal with an output resistance of 1k Ohm, it gives a precise temperature reading which is mostly used in the control of the HVAC systems. This sensor is used in controlling heating, ventilating and air conditioning systems through real-time outdoor temperature information. This not only increases the value chances for the system, but also increases the life of HVAC equipment by avoiding overworking of the systems.
