Overview
The LABTOP BC217E bath thermostatic circulator is a thermostatic circulator with a heating head that can reach room temperature or -20 ° C by chilling down the coil and external circulating water or chilling down the bath. The bath body is made of all stainless steel and filled with aluminum silicate cotton insulation, providing an economical solution for placing the sample directly in the bath for thermostatic testing. Optional external circulation adapter and external temperature sensor PT100 for external temperature control and cycling applications, suitable for sample temperature control, material testing, quality control and analysis.
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 timing heating, cooling, thermostatic, slope and various time settings, the maximum time of each program is 999 hours.
4. Equipped with external temperature sensor interface, optional movable external temperature sensor, combined 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. A variety of operation modes are optional, and accidental power failure can be automatically restored, including mode 1: power-on equipment stops after power failure, and the set value can be changed; mode 2: power-on automatic operation after power failure, and the set value can be changed; mode 3: power-on automatic operation after power failure, and the set 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 BC217E bath thermostatic circulator achieves temperature control through a heating head and chill down coil. With the help of external circulating water or chill down bath, the temperature can reach room temperature or -20 ° C. The intelligent PID Control mode, combined with the Pt100 temperature sensor and optional external temperature sensor, uses PID TAC control technology, Cascade cascade control technology and bath internal and external temperature difference lock control technology to precisely adjust the temperature. The pressure/suction pump automatically adapts to the external load to ensure stable circulation.
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. Optional external circulation adapter or external temperature sensor PT100 as required.
3. Set the overtemperature protection temperature through the knob.
4. Select the operation mode (Mode 1, Mode 2 or Mode 3).
5. Optional multi-stage programmable controller to set program parameters such as temperature, time, etc.
6. Start equipment, monitor Temperature Fluctuations and pump operation status.
7. Optional Remote Communication interface control equipment start and stop.
Notice
• Ensure that the Ambient Temperature is within the range of 5~ 32 ° C and the relative humidity does not exceed 80%.
• Avoid the equipment from dry burning when the program fails, and use the hardware over-temperature protection function.
• When using flammability bath, it must meet the DIN12876 standard level III safety requirements.
• The pump connection interface is M16x1mm to ensure proper connection to the external circulation system.
• The equipment is fixed by Benchtop, which is placed smoothly to avoid dumping.
• Allows continuous operation of 100%, but requires regular inspection of liquid level protection and over-temperature protection functions.
• When selecting external alarms and solenoid valves, wire them correctly to prevent malfunctions.
