HSIN9000 Intelligent Thermocouple / Thermal Resistance Automatic Control Calibration System
Feature
1.Intelligent temperature control system：It adopts imported high-precision temperature controller, large LCD display, quasi five digit display and double row data display at the same time;The temperature control instrument has the function of self-tuning, which can be automatically adjusted through the self-tuning program, so that customers can easily set the PID parameters of the fixed inspection points of each verification furnace,once setting, the setting parameters are valid for a long time without obvious environmental changes
2.The device can automatically verify industrial thermocouples with various graduation numbers, two-wire, three wire and four wire thermal resistors, Expansion thermometers and temperature secondary instruments.It can verify the low-temperature thermocouple in the low-temperature oil tank.The multi-channel scanning device is 24 channels, which can be dynamically expanded on demand;
3.It adopts industrial structure and has strong anti-interference ability.
4.It has excellent switching performance. The switching substrate adopts large-area gold coating material, and the parasitic thermal potential is less than 0.4 μ V
5.The switch has small contact resistance and good consistency
6.Special low potential terminal block
7.It is compatible with the wiring of thermocouple and thermal resistance.The four wire resistance measurement method completely eliminates the resistance of external leads.
8.The integrated temperature control system can automatically adjust the power of the verification furnace, and the verification furnace has good long-term stability
9.The temperature control system has its own actuator. High power solid state relay (SSR) with photoelectric isolation function is used to control thermocouple verification furnace (or constant temperature oil tank and water tank), which has high reliability
10.The PID automatic control and adjustment parameters of the temperature control system provide the necessary basic conditions for precision temperature control
11.The temperature control system has perfect power supply circuit protection measures.It has high reliability and safety. It has the functions of high temperature automatic alarm and self-processing.
12.It can realize the real simultaneous verification of thermal resistance and thermocouple, and greatly improve the work efficiency
13.With a high degree of automation, it can automatically complete all work in the process of line inspection, temperature control and verification, and automatically carry out verification data processing, data storage, statistics and printing verification certificates
14.It can be automatically verified by computer, or it can choose to manually operate each independent intelligent device for semi-automatic verification
15.It can test the temperature field of verification furnace, oil tank and water tank
16.It can be extended to group control and control multiple calibration furnaces, oil tanks and water tanks at the same time
17.The system software is programmed with net on Windows platform and has a full Chinese operation interface, which is convenient and fast.
