First, the use of occasions and customer requirements
The end customer is the manufacturer of the sensor. It requires a very high precision thermostat to give a high precision standard temperature point. The end customer purchases the constant temperature oil tank of the supporting manufacturer and purchases our 5600 meter for Measure the contrast and determine the accuracy of the measured temperature.
The constant temperature oil tank is composed of a high-precision instrument AIJ, which is composed of a heating wire, a mixer, a compressor and the like.
Second, the way to achieve
The AIJ meter controls the temperature of the internal liquid through the heating wire and increases the temperature uniformity through the mixer. When it is necessary to detect the low temperature accuracy of the probe, it is necessary to open the compressor to control the low temperature. In order to ensure the measurement accuracy, the measurement is compared with 5600. After the temperature is completely stabilized at the required temperature, the final fluctuation is generally less than 0.005 degrees Celsius, and then the accuracy of the test probe or thermometer is compared and tested.
Third, the relevant parameters and debugging situation
INP=9 is measured with PT100, CHYS=0.05, and the hysteresis will be effective in auto-tuning. It is used to avoid frequent adjustment due to fluctuations in measured input values. The effective range of PID is also determined in the AIJ instrument. The PID parameters are determined by the instrument. Self-tuning is obtained, which affects the control effect of the instrument.
In the debugging, there is a large error in the measurement display. The final result is that the AIJ5.0 is connected to the three-wire PT100, which corresponds to the 17, 18, and 19 terminals. It is different from the AI ​​series and the old version of the AIJ. After that, the measurement error is significantly smaller, and the final control effect is also in line with customer requirements.
Fourth, choose our products
AIJ5.0AK5AL2A is selected with thyristor for precise adjustment. AI5600 is used to measure temperature and compare with AIJ instrument to determine measurement accuracy.
V. Conclusion
The application of AI instruments in the sensor industry requires extremely high measurement accuracy and control accuracy. It is best to use both control instruments and measuring instruments at the same time, and the resolution of the control instruments must be high enough.
