Overview
The BC220E bath thermostatic circulator is a thermostatic circulator with heating head from the BC series of LABTOP brand. With the help of external circulating water or chilled down liquid tank, the temperature can reach room temperature or -20 ° C. The bath body is made of all stainless steel and filled with aluminum silicate cotton insulation, providing an economical solution for the sample to be placed directly in the water bath for thermostatic test. Optional external circulation adapter and external temperature sensor PT100 can be used for external temperature control and circulation applications. It is suitable for temperature control, material testing, quality control and analysis of samples. It uses environmentally friendly natural refrigeration with liquid level protection and over-temperature protection functions.
Features
1. Hardware over-temperature protection, users can set the protection temperature through the knob, and dry burning can still be avoided when the equipment program fails. It meets the DIN12876 standard level III and can use flammability bath liquid.
2. Maintenance-free pressure/suction pump, pump pressure and Flow rate automatically adapt to external load.
3. Optional multi-stage programmable controller, support multi-stage program control, such as regular heating, cooling, thermostatic, slope and each period of time, each program can be set to run up to 999 hours.
4. Equipped with external temperature sensor interface, optional movable external temperature sensor, with PID TAC control technology, Cascade cascade control technology and bath internal and external temperature lock control technology, precise control of bath external material temperature.
5. Pt100 temperature sensor, supports single point, two point and multi point temperature calibrating.
6. Parts that come into contact with liquids or vapors are made of high-performance stainless steel and high-performance plastics.
7. Optional related accessories can be used to form different internal and external applications.
8. The buzzer can be set to silent or audible.
9. Multiple operation modes are optional, and accidental power failure can be automatically restored: Mode 1 (power-on equipment stops after power failure, setting value can be changed), Mode 2 (power-on automatic operation after power failure, setting value can be changed), Mode 3 (power-on automatic operation after power failure, setting value cannot be changed).
10. The device serial number can be queried through the software.
11. Optional intelligent control function: a variety of interfaces (RS485, RS232) to achieve remote communication, control equipment start and stop.
12. Optional normally open and normally closed 2 external contact points, connected to the external alarm.
13. Optional set of 12V switch Output signal to control external solenoid valve.
14. Optional set of 5V external input switch signals for external smart devices to control the start and stop of the instrument.
15. Optional 0-10V or 4-20mA analog signal input for external smart devices to control the start and stop of the instrument.
Principle
The BC220E bath thermostatic circulator achieves temperature control through a heating head and chill down coil combined with external circulating water or chill down bath. Temperature range up to -20 ° C to 150 ° C. Intelligent PID Control mode and Pt100 temperature sensor combined with optional external temperature sensor and PID TAC, Cascade cascade control, bath inside and outside temperature difference lock control technology ensure precise and stable temperature. The pressure/suction pump automatically adapts to external loads, providing cycle power to support internal and external applications.
Applications
Sample temperature control, material testing, quality control, analysis
Steps
Connect the power supply to ensure that the voltage is within the range of 200 to 230VAC/50Hz.
2. Set temperature and protection parameters as required, optional external Sensor or accessories.
3. Start the device and monitor the temperature display and operating status.
4. Optional remote control or programming mode for multi-stage program operation.
5. Turn off the equipment after use, clean and maintain it.
Notice
• Ensure that the Ambient Temperature is within the range of 5~ 32 ° C and the relative humidity does not exceed 80%.
• To avoid dry burning, use the hardware over-temperature protection function to set the appropriate temperature.
• Safety level III must be met when using flammability bath.
• Regularly check whether the liquid level and over-temperature protection function are normal.
• When selecting an external alarm or solenoid valve, connect the interface correctly.
The equipment is allowed to operate continuously for 100%, but it must be operated under permissible conditions.
