## Summary description

DANFOSS QT temperature sensor (model 003Z0397) is designed to measure and monitor temperatures in the 35–50°C range. It provides reliable temperature sensing for HVAC and industrial control applications, enabling accurate feedback for controllers, thermostats or safety cut-offs. Suitable for integration into heating circuits, boilers, pump systems and equipment monitoring.

## Long description

DANFOSS QT temperature sensor model 003Z0397 measures and monitors temperatures in the 35–50°C range. Designed for HVAC and industrial control applications, this sensor provides stable analog temperature feedback suitable for integration with controllers, thermostats, safety cut-offs and monitoring equipment. The compact sensor fits into heating circuits, boilers and pump systems to help maintain process temperatures and trigger control actions where precise mid-range temperature detection is required.
Advantages
The sensor offers reliable and repeatable temperature detection within the specified range, with a design that supports straightforward installation in heating and pump systems. It provides compatible feedback for common control devices and safety interlocks, enabling accurate regulation and protection of equipment. The construction is intended for typical HVAC and industrial environments where a focused 35–50°C sensing window is required.
Suitable for
 Temperature monitoring in heating circuits and boilers
 Feedback input for controllers and thermostats
 Pump system temperature supervision
 Safety cut-off or alarm activation at defined mid-range temperatures
When it may not be suitable
This sensor is calibrated for the 35–50°C range and is not appropriate for applications requiring measurement below 35°C or above 50°C, where accuracy and response may degrade. It is also not intended as a precision laboratory instrument for high-accuracy scientific measurements outside its specified range.
Key specifications
 Measuring range: 35–50°C
 Application scope: HVAC and industrial control environments
 Output: temperature feedback suitable for controllers and thermostats (analog type dependent on system)
 Typical mounting: integration into heating circuits, boilers and pump systems
 Operating environment: designed for standard heating system conditions
How to use
Install the sensor at the point where representative medium temperature is required, for example in a sensor pocket or a designated mounting point in a heating circuit or boiler. Connect the sensor wiring to the controller or thermostat according to the receiving device’s input requirements and wiring diagram. After mechanical and electrical installation, verify correct operation by comparing readings against a reference or by observing controller behaviour across the operating range. Follow local electrical and mechanical safety rules during installation and commissioning.
What to consider before purchase
 Ensure the required measurement range (35–50°C) matches your application needs
 Confirm compatibility of the sensor’s output type with your controller or thermostat input
 Verify suitable mounting provisions (sensor pocket, insertion length or mounting point) in the system
 Check environmental conditions to ensure the sensor design matches expected temperatures and medium
Usage recommendations
For reliable performance, install the sensor where it senses the process medium directly and minimize thermal bridges to surrounding structures. Periodically verify sensor readings as part of routine maintenance and replace if readings drift outside acceptable limits.
