Wholesale Discount TU-1A90 thermal wax actuator for automobile thermostat to Netherlands Factory Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

The examples utilize everyday appliances, like a toaster and a shower, to help you understand the basic structure and working principles of a feedback control loop. The first example shows how a toaster can be controlled to cook bread perfectly by continuously monitoring the bread’s color. It also shows how feedback control deals with system variations (like different types of bread).
The second example outlines how feedback control can help regulate water temperature in a shower. It demonstrates how the feedback control system can compensate for unexpected environmental changes acting on the system – such as someone running a dishwasher at the same time as the shower.
In sum, feedback control measures the actual output of a system (like toast in the first example or water temperature in the second) by using a sensor (eyes in both of the examples). Based on the difference between the desired and the measured output, a controller (human in both of the examples) sends a signal to a device (in these cases, the toaster or the shower). The signal makes the device’s output achieve the desired value despite system variations or unexpected environmental events.
This is a circuit that uses a thermistor to turn on a fan when a certain temperature is exceeded. This video contains the actual testing of the circuit, the components list, and the schematic diagram of the circuit. We used this as part of our project which also included a heating system which turns on when it goes below a certain temperature and it comes with an LCD to display the current temperature of the room.
