Thermostat Testing Device
The Thermostat Testing Device is a dedicated system for life cycle testing of snap-action thermostats. You use this equipment to alternately expose the thermostat sensing surface to controlled hot and cold air streams, creating precise thermal cycling conditions. Through repeated heating and cooling, the device reliably triggers thermostat on and off actions, allowing you to evaluate switching performance, durability, and electrical continuity over extended test cycles. PLC and touchscreen control provide accurate parameter setting, real-time monitoring, and clear fault indication.

FAQ
1. What types of thermostats can you test with this device?
You can test snap-action thermostats and similar temperature control components that operate through thermal switching.
2. How does the device trigger thermostat switching?
It alternates controlled hot and cold air streams on the sensing surface, creating thermal cycles that trigger on and off actions.
3. How many samples can be tested at the same time?
The device supports up to ten samples simultaneously through independent load channels.
4. How does the system detect thermostat failure?
Each channel includes current detection. When conductivity is lost or abnormal, the system identifies open or short circuits and stops the test.
5. Is fault information displayed clearly during testing?
Yes. The HMI displays the fault type and affected channel when a failure occurs.
6. Can you adjust test parameters easily?
Yes. All test parameters are configured directly through the PLC-controlled touchscreen interface.
