Overview
The OBC213EB is an open bath thermostatic circulator of the LABTOP brand, featuring stainless steel sinks with a maximum Operating temperature of 200 ° C and a volume of 13L. The device is room temperature controlled by chilling down coils and external circulating water, providing an economical thermostatic test program, supporting external temperature control and recycling application options. Suitable for areas such as temperature control, material testing, quality control and analysis of samples, using environmentally friendly natural refrigerants, with liquid level protection and over-temperature protection. It meets Safety level III/FL, can use flammability liquids, and meets DIN 12876 standards.
Features
1. Low liquid level protection to prevent dry burning
2. Hardware over-temperature protection, the user can set the protection temperature through the knob, and still avoid dry burning when the equipment program fails, in line with DIN12876 standard level III, flammability bath liquid can be used
3. Maintenance-free pressure/suction pump, pump pressure and Flow rate automatically adapt to external load
4. Optional multi-stage programmable controller, support timing heating, cooling, thermostatic, slope and various time settings, the maximum time of each program is 999 hours
5. Equipped with external temperature sensor interface, optional movable external temperature sensor, with PIDTAC control technology, Cascade cascade control technology and bath internal and external temperature lock control technology, precise control of bath external material temperature
6. Pt100 temperature sensor, support single point, two point and multi point temperature calibrating
7. Liquid or steam contact parts are made of high-performance stainless steel and high-performance plastics
8. Optional related accessories to form different internal and external applications
9. The buzzer can be set to silent or audible
10. Multiple operation modes are optional, and accidental power failure can be automatically restored, including mode 1 (the next power-on device stops, the setting value can be changed), mode 2 (the next power-on automatic operation, the setting value can be changed) and mode 3 (the next power-on automatic operation, the setting value cannot be changed)
11. The device serial number can be queried through the software
12. Optional intelligent control functions: a variety of interfaces (RS485, RS232) to achieve remote communication and control equipment start and stop
13. Optional normally open and normally closed 2 external contact points, can be connected to external alarms
14. Optional set of 12V switch Output signal for controlling external solenoid valve
15. 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
16. Optional 0-10V or 4-20mA analog signal input, can be used for external smart devices to control instrument start and stop
Principle
OBC213EB open bath thermostatic circulator uses intelligent PID Control mode, uses Pt100 temperature sensor to monitor temperature, combines chill down coil and external circulating water to achieve temperature regulation. The equipment uses pressure/suction pump to automatically adapt to external load to ensure thermostatic circulation. Optional external temperature sensor and adapter, through PIDTAC control technology, Cascade control technology and bath internal and external temperature difference lock control technology, precise control of bath external material temperature.
Applications
Sample temperature control, material testing, quality control, analysis
Steps
1. Connect the power supply to ensure that the Ambient Temperature is within the range of 5~ 32 ℃
2. Select the operation mode (Mode 1, Mode 2 or Mode 3) as needed
3. Set temperature parameters, optional multi-stage program control (such as regular heating, cooling, thermostatic)
4. Start the equipment, monitor temperature fluctuations and pump operation status
5. Optional External Sensor or Accessories for External Temperature Control and Circulation Application
6. After use, turn off the device according to the specifications
Notice
• Ensure that the Ambient Temperature is within the range of 5~ 32 ° C, and the relative humidity does not exceed 80%
• Check the liquid level before use to avoid dry burning. The equipment has a low liquid level protection function
• Set the hardware overtemperature protection temperature to prevent overheating due to program failure
• Power supply voltage within 200~ 230VAC/50Hz range
Allows 100% continuous operation, but requires regular maintenance of the pump and Sensor
• Optional accessories, follow the installation guide
• Buzzer settings are adjusted according to demand to avoid interference
• Ensure compatibility and security when using external interfaces and signals
