Upgrade your heating, ventilation, and air conditioning systems with Siemens' QAC31... Outside Temperature Sensors. These advanced sensors are designed to provide accurate temperature data for a variety of applications, making them an invaluable addition to your commercial spaces. Let's dive into the key features that set these sensors apart.
Key Features:
-
Active Temperature Sensors: The QAC31... sensors actively monitor the outside temperature, ensuring precise data acquisition for your control systems.
-
Versatile Power Options: These sensors support both AC 24 V and DC 13.5…35 V power supplies, providing flexibility for different setups.
-
Multiple Output Signals: Choose from two output signals, DC 0...10 V or 4...20 mA, depending on your specific requirements.
-
Wide Measuring Range: With a measuring range of -50...+50 °C, these sensors offer reliable temperature data across a broad spectrum.
-
Reliable Functionality: Siemens' reputation for reliability extends to the QAC Series. These sensors can be used as reference or measuring sensors, making them ideal for a wide range of applications.
-
Effortless Ordering: When ordering, simply provide the name and type reference, and you're good to go. Each sensor comes complete with a cable entry gland M16 for easy installation.
Functionality and Design:
The QAC31... sensors work by detecting outside temperature through a sensing element that reacts to temperature changes. This data is then converted into an output signal, either DC 0...10 V or 4...20 mA, depending on the sensor type and selected temperature range. The result is accurate, real-time temperature information to support your control systems.
The mechanical design of these sensors is robust, featuring a two-sectional housing with a base and removable cover. The printed circuit board, connection terminals, and measuring probe are intelligently organized within the housing. This design allows for concealed or surface-run wiring, enhancing the overall aesthetics of your setup.
The setting element, located inside the cover, is easy to adjust. With three plug positions for temperature measuring range and an optional test function, you have control at your fingertips.
Engineering Notes:
To power these sensors, a transformer for safety extra low-voltage (SELV) with separate windings for 100% duty is required. When selecting and protecting the transformer, be sure to adhere to local safety regulations.
Choose Siemens' QAC31... Outside Temperature Sensors to elevate your temperature control solutions. These sensors are engineered to deliver accuracy and reliability, ensuring optimal performance in your heating, ventilation, and air conditioning systems. Upgrade your control and automation systems today for greater efficiency and peace of mind.
