6. Can be domestic circulation, external circulation, maintenance-free pressure/suction pump, resistant to fiber and metal particles, can be stirred in the horizontal and vertical directions of the bath liquid, so that the mixing is more uniform, pump pressure and Flow rate automatically adapt to external load.
7. Parts that come into contact with liquids or vapors are made of high-performance stainless steel and high-performance plastics.
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 functions: a variety of interfaces (RS485, RS232) to achieve remote communication and control the start and stop of equipment.
13. Optional 0-10V or 4-20mA analog signal input can be used 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 precisely senses the temperature of the bath or external materials through an intelligent PID Control system combined with a Pt100 temperature sensor. Temperature regulation with an integrated heating and cooling module (using environmentally friendly natural refrigerants). The domestic circulation of the bath liquid is driven by a maintenance-free pressure/suction pump, and the bath liquid can be stirred horizontally and vertically to ensure uniform temperature. When connected to an external Sensor, the system can use technologies such as Cascade cascade control to achieve precise temperature control of the external materials of the bath.
Applications
Sample temperature control, material testing, quality control, chemical analysis
Standards
Safety level III/FL can use flammability liquids according to DIN 12876
Steps
1. Ensure that the equipment is placed in the allowable environment conditions (Ambient Temperature 5~ 32 ℃, relative humidity ≤ 80%), and connect to the required power supply (200~ 230VAC/50Hz).
2. Add an appropriate amount of bath liquid to the Tank, pay attention to the liquid level, and avoid dry burning.
3. Optionally connect external temperature sensor PT100 or external circulation adapter.
4. Set the required temperature program (including heating, cooling, thermostatic and various periods) through the instrument panel or optional multi-stage programming controller.
5. Select the operation mode (such as power failure recovery mode) and buzzer prompt mode as needed.
6. Start the equipment and the system will start working, ensuring uniform temperature through pump circulation and stirring.
7. During operation, the real-time temperature (resolution 0.01 ° C) and equipment status can be monitored through the LED display.
8. After the experiment, shut down the equipment according to the procedures and perform necessary cleaning and maintenance (e.g. cleaning the removable dust net cover).
Notice
Please read the instructions carefully before use and ensure that the operator is trained.
* Equipment must operate at the allowable Ambient Temperature (5~ 32 ° C) and relative humidity (≤ 80%).
* Power supply voltage 200~ 230VAC/50Hz, and reliable grounding.
Be sure to check the liquid level of the bath before operation to prevent low-level dry burning. The equipment has a low-level protection function.
The equipment is equipped with over-temperature protection, but it is still necessary to avoid long-term overrun.
* When using flammability liquids as bath liquids, ensure compliance with Safety level III/FL requirements.
The maximum pressure and suction of the pump should not exceed the rated value (pressure 0.2 bar, suction 0.1 bar, specific models may be higher).
When performing external loops or connecting external devices, ensure that the interface (e.g. M16x1) is firmly connected and leak-free.
* Regularly clean the removable trend dust net cover to ensure heat dissipation and normal operation.
Before moving or maintaining equipment, be sure to disconnect the power supply.
* If the device alarms (e.g. low liquid level, over temperature), please check the cause in time, and do not force operation before Troubleshooting.
* For the installation and use of optional functions (such as remote communication, external alarm touch points, etc.), please refer to the relevant option instructions.
