Overview
The OBC327EB is an open bath thermostatic circulator of the LABTOP brand. It features a stainless steel sink with a maximum Operating temperature of 200 ° C and a volume of 27L. The device is temperature controlled to room temperature by chilling down the coil and external circulating water, providing an economical thermostatic test program. Optional external circulation adapter and external temperature sensor PT100 for external temperature control and cycling applications, suitable for areas such as sample temperature control, material testing, quality control and analysis. Using environmentally friendly natural refrigerant with liquid level protection and over-temperature protection, compliant with 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 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 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, 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: Mode 1 (power-on equipment stops after power failure, setting value can be changed), Mode 2 (power-on equipment automatically runs after power failure, setting value can be changed), Mode 3 (power-on equipment automatically runs 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 OBC327EB achieves precise temperature control through intelligent PID control technology and Pt100 temperature sensor. The device uses a chill down coil and external circulating water to reduce the temperature to room temperature, providing a thermostatic environment for the sample to be placed directly in the water bath. Optional external circulation adapter and external temperature sensor, combined with PIDTAC control technology, Cascade cascade control technology and bath internal and external temperature difference lock control technology, achieve precise control of 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
4. Optional External Sensor or Accessories for External Temperature Control and Circulation
5. Start the device and monitor the running status
6. Turn off the equipment after use for cleaning and maintenance
Notice
• Make sure the liquid level is normal and prevent dry burning
• Set the hardware overtemperature protection temperature to avoid the risk of program failure
• Permissible Ambient Temperature 5~ 32 ℃, relative humidity does not exceed 80%
• Safety level III/FL when using flammability liquids
• The equipment is fixed by Benchtop to ensure stable placement
• Power supply voltage is 200~ 230VAC/50Hz, which needs to be matched
• Optional features need to be properly configured, such as external alarms or intelligent control interfaces
