Temperature controller, according to the temperature change of the working environment, physical deformation occurs inside the switch, resulting in some special effects, a series of automatic control elements that produce on or off actions, or electronic components at different temperatures, the working state Different principles are used to provide temperature data to the circuit for the circuit to collect temperature data. Before we use the temperature controller, we must first set the parameters of the temperature controller, so that the temperature controller can be used correctly. So, how to set the temperature controller?
Taking PCE-D9000 Oven Incubator Bath Temperature Controller as an example, the method of temperature controller setting is:
1. After connecting the temperature controller instrument, turn the switch to the "lower limit setting" position, and turn the corresponding lower limit setting knob at the same time. At this time, the digital display is the required lower limit temperature value.
2. Turn the temperature controller switch to the "upper limit setting" position, and turn the corresponding upper limit setting knob at the same time. At this time, the digital display is the required upper limit temperature value.
3. Turn the temperature controller switch to the "measurement" position, and the digital display is the actual temperature value of the measured object.
4. When the actual temperature value is lower than the lower limit set value, the green light is on, and the upper limit relay is always low-passed and total high-off; when the actual temperature reaches or exceeds the lower limit set value but is still lower than the upper limit set value, the green light is on. The red lights are all off, the lower limit relay is always low-off, total high-pass, the upper limit relay is total low-pass, total high-off, when the actual value reaches or exceeds the upper limit set value, the red light is on, here the upper limit relay is always low off, total high pass.
5. Generally, when used for temperature control, the lower limit relay output can be used for auxiliary heating control, and the upper limit can be used for heating control, or the lower limit relay output can be used for temperature control, and the upper limit relay output can be used for over-temperature alarm. For instruments with suffix "F", the upper required temperature value must be adjusted to be higher than the lower required temperature high value.
6. When the actual value is lower than the lower limit, the green light is on, the relay is always low-passed, and the temperature rises; when the actual value is higher than the lower limit and lower than the upper limit, it is still the total low-pass, and the temperature is raised; When the limit value is reached, the red light is on, the relay is always high-passed and the total low-pass is disconnected, and the heating is stopped. Only when the actual temperature value is lower than the lower limit, the green light is on, and the total low-pass is repeated. There is only one relay output for the whole process, so that it can be easily matched with the load.
The above is the setting method of the temperature controller for you. The setting method of different temperature controllers is different, so we must carefully read the manual of the temperature controller before using the temperature controller, and set the temperature control according to the manual. device, so as to ensure the correctness of the parameters. If you have a need for temperature controllers, please contact Peaks, a professional manufacturer of Intelligent Temperature Controllers, to solve your problems in performing experiments at various temperatures.
