8. Pt100 temperature sensor, can perform two-point and multi-point temperature calibrating.
9. Removable trend dust net cover, easy maintenance.
10. The buzzer can be set to silent or audible.
11. Multiple operation modes are optional, and accidental power failure can be automatically restored.
12. Optional intelligent control function: a variety of interfaces (RS485, RS232) to achieve remote communication, control equipment start and stop.
13. Optional 0-10V or 4-20mA analog signal input for external smart devices to control the start and stop of the instrument.
14. The device serial number can be queried through the software.
15. Optional normally open and normally closed 2 external contact points, can be connected to external alarms.
16. Optional set of 12V switch Output signal for controlling external solenoid valve.
17. An optional set of 5V external input switch signals can be used for external smart devices to control the start and stop of the instrument.
Principle
The thermostatic circulator accurately detects the temperature through the intelligent PID Control system combined with the Pt100 temperature sensor. System integration heating and cooling function, using proportional refrigeration control technology to output the cooling capacity on demand, and through the CIT technology implementation of high temperature rapid start Compressor cooling. Circulation pump drives the bath liquid in the tank or external circulation, and horizontal and vertical two-way stirring to ensure uniform temperature. Multiple control technologies (such as PID TAC, Cascade cascade control, temperature difference lock control) cooperate with the external Sensor to achieve accurate temperature control of the external material of the bath.
Applications
Sample temperature control, material testing, quality control, analysis
Standards
Safety level III/FL can use flammability liquids according to DIN 12876
Steps
1. Check the Power supply voltage (200~ 230VAC/50Hz) and environmental conditions (Temperature 5~ 32 ℃, Humidity ≤ 80%).
2. Add an appropriate amount of bath liquid to the bath to ensure that the liquid level is normal and avoid dry burning.
3. Connect the power supply and turn on the power switch of the device.
4. Set the required temperature, program (up to 30 segments) and Miscellaneous parameters (such as running time, slope) through the LED display and controller.
5. Connect external circulation pipeline or external temperature sensor (PT100) as needed.
6. Start the equipment, the circulating pump starts to work, and the equipment is heated, cooled or thermostatic controlled according to the settings.
7. During operation, real-time temperature, program segment status, and other information can be monitored through the display screen.
8. When the operation is over or needs to be stopped, press the stop button to stop the heating/cooling and circulation of the equipment.
9. Turn off the power supply, if you need cleaning or maintenance, you can remove it into the trend dust net cover for cleaning.
Notice
• Before use, please ensure that the Power supply voltage of the equipment meets the requirements (200~ 230VAC/50Hz).
Equipment should operate under permissible environment conditions (Ambient Temperature 5~ 32 ℃, relative humidity ≤ 80%).
• Pay attention to the liquid level of the bath to avoid low liquid level dry burning. The equipment has a low liquid level protection function.
Equipment is equipped with over-temperature protection, but it is still necessary to avoid long-term overload operation.
• When using flammability liquids, ensure compliance with Safety level III/FL standards.
• When external cycling or using an external Sensor, make sure the connection is correct and the sealing is good.
• Regularly clean the removable trend dust net cover to keep the equipment well dissipated.
• The device has a variety of power-off recovery modes, please set it before operation according to actual needs.
• When performing program control, please carefully set the parameters of each section (temperature, time, slope, etc.).
When maintaining, ensure that the equipment is powered off and that components that come into contact with liquids or steam are made of stainless steel or high-performance plastics.
