B. Working Principle
The Subzero SZ-T75-1500 works on the principle of an NTC thermistor. NTC means Negative Temperature Coefficient.
In simple terms, when the temperature increases, the resistance of the sensor decreases. When the temperature decreases, the resistance of the sensor increases. The temperature controller reads this resistance change and converts it into a temperature value.
This allows the controller to switch cooling, heating, alarm or control outputs based on the actual temperature measured by the sensor.
C. Why It Is Used
The Subzero SZ-T75-1500 NTC sensor is used because it offers accurate and stable temperature measurement in compact temperature control systems.
It is useful for:
- Measuring temperature in cold storage rooms
- Monitoring temperature in refrigeration systems
- Sensing temperature in chillers and cooling machines
- Connecting with Subzero digital temperature controllers
- Maintaining temperature in HVAC and process equipment
- Protecting machines from overheating or overcooling
- Improving temperature control accuracy in industrial applications
The brass tube construction makes it suitable for general industrial and refrigeration use where a durable metal sensing probe is required.
