3 Terms
JJF 1001-2011, JJF 1007-2007 defined and the following terms and definitions apply to this specification.
3.1 temperature switch temperatureswitch
Temperature reaches a specific value to produce switching elements or devices.
3.2 Operating temperature operatingtemperature
Temperature switch contact is closed (normally open) or disconnected (normally closed) corresponds to the actual temperature value.
3.3 Reply temperature recoverytemperature
When the contact of the temperature switch is closed or opened, the contact of the temperature switch is opened (normally open) or closed (normally closed)
The actual temperature should be.
3.4 setpoint setpoint
You want the temperature switch to be closed (normally open) or open (normally closed) temperature.
3.5 Operating temperature error operatingtemperatureerror
The difference between the operating temperature and the set value.
3.6 on-off temperature difference temperaturedifferenceofopenandclosedpoint
The absolute value of the difference between the action temperature and the recovery temperature.
4 Overview
Temperature switch is the temperature reaches a specific value to produce switching elements or devices, mainly by the temperature-sensitive components and moving
For switching and other components, play a role in control, protection and restrictions, are widely used in motors, household appliances and so on.
According to the working principle can be divided into bimetallic, pressure type, electronic type, working principle shown in Figure 1, Figure 2 and Figure 3.
According to the regulation can be divided into fixed, adjustable, according to the switch at room temperature can be divided into normally open and normally closed.
