Overview
The OBC206EA is an open bath thermostatic circulator of the LABTOP brand, using a transparent polycarbonic acid ester water bath with a maximum Operating temperature of + 100 ° C and a volume of 6L. The device is room temperature controlled by chilling down the coil with external circulating water, providing an economical solution for the sample to be placed directly in the water bath for thermostatic testing. Optional external circulation adapter and external temperature sensor PT100 are available for external temperature control and recycling applications, suitable for sample temperature control, material testing, quality control, analysis and other fields. Using environmentally friendly natural refrigeration, with liquid level protection and over-temperature protection, according to Safety level III/FL, can use flammability liquids, and comply with DIN 12876.
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 can still over-temperature protection when the equipment program fails to avoid dry burning, 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, users can realize multi-stage program control, such as regular heating, cooling, thermostatic, slope and each period of time, each program can set the running time, up to 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, 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: 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)
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, 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
The OBC206EA open bath thermostatic circulator uses intelligent PID control technology combined with the Pt100 temperature sensor to monitor the temperature in real time for accurate temperature control. The equipment uses a pressure/suction pump to automatically adapt to the external load, and uses a chill down coil to control the temperature within the room temperature range with the help of external circulating water to ensure stable temperature in the bath. Optional external temperature sensor and adapter are available to expand external temperature control and circulation applications, and use PIDTAC, Cascade cascade control and thermolock technology to precisely control the temperature of external materials.
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. Set Temperature and Miscellaneous Parameters as Required, Optional External Sensor or Adapter
3. Start the equipment, monitor temperature fluctuations and operating status
4. Optional programming multi-stage control program, setting time, slope and other parameters
5. After use, turn off the device according to the specifications
Notice
- Ensure Ambient Temperature in the range of 5~ 32 ℃, relative humidity does not exceed 80%
- Avoid dry burning and pay attention to whether the liquid level protection function is normal
- When using flammability liquids, ensure compliance with Safety level III/FL
- Regularly check the hardware overtemperature protection settings to prevent program failure
- Optional accessories installed, follow the Operation Manual
- Power supply voltage within 200~ 230VAC/50Hz range
- 100% continuous operation of the equipment is allowed, but the operating status needs to be monitored
