Siemens Sensor, Duct Sensor Type, Flange Mounting Type - QFM2120
This sensor is a robust HVAC sensor designed for accurate measurement of relative humidity and temperature within ducts. With compact dimensions of 80mm x 80mm x 88mm, this flange mount temperature sensor is ideal for installations requiring precise environmental monitoring. The sensor operates effectively in a voltage 2 to 28.8V AC or 13.5 to 35V DC, and boasts an IP54 rating for ingress protection, making it suitable for various industrial environments.
Features & Benefits
• Measures relative humidity with a typical accuracy of ±3%
• Operates within a wide temperature range of -35°C to +50°C
• Provides multiple signal outputs including 4 to 20mA and DC 0 to 10V
• Suitable for duct mounting, ensuring secure installation
• Compact design features screw termination for easy wiring
• Designed for high-temperature applications, operating up to +70°C
Applications
• Utilised as control sensors in supply or extract air systems
• Ideal for reference measuring, assisting with dew point shift
• Serves as limit sensors in conjunction with steam humidifiers
• Used for building automation systems to monitor humidity levels
• Enables accurate humidity and temperature readings in HVAC systems
What type of connection does it require for installation?
The sensor features a screw termination design, allowing for straightforward wiring with compatible terminals, making installation efficient.
Can it operate under high voltage conditions?
The device operates within an AC voltage 2 to 28.8V and a DC 5 to 35V, ensuring it meets various system requirements without damage.
How does it maintain accuracy in fluctuating environments?
With built-in circuitry, it measures relative humidity and temperature simultaneously and compensates for environmental changes to ensure consistent accuracy.
Is it suitable for use in outdoor applications?
Although it has an IP54 rating for water and dust ingress, it is primarily designed for indoor duct applications within HVAC systems and may not withstand outdoor exposure.
What factors should be considered for cable selection when using the sensor?
When selecting cables, consider the maximum permissible lengths and use shielded twisted pair cables in environments with high electromagnetic interference to ensure reliable performance.
