Overview LGK-JS03 Mould Breakout Prediction System Thermocouple Calibrator is a patented product of Wuhan CenterRise M&C Engineering Co., Ltd. It is a special equipment specially developed for off-line detection of mold breakout prediction thermocouples. This calibrator has the advantages of high test accuracy, reliable data, light weight, portable and easy to use. It can fully meet the needs of on-site installation testing and use process verification. It is an essential tool for on-site online testing. The detection principle In the process and normal production of mold thermocouple offline installation in mold breakout prediction system, LGK-JS03 mould breakout prediction system thermocouple calibrator is an automatic special instrument for thermocouple detection. The system simultaneously measures the wide surface inner arc, wide surface outer arc and narrow surface of the mold through a special embedded signal processing system. The 128 thermocouple sensors can be scanned on one side at most, and the current thermocouple status is displayed in real time on the LCD panel of the calibrator. The function of the system 1. Using digital dynamic measurement technology, it can measure up to 8x16 thermocouple arrays’ temperature at the same time 2. Realize full digital measurement 3. The system realizes automatic temperature compensation and automatic recording 4. Multiple modes of display output, providing a rich and complete human-machine interface 5. Provide single-point, cycle, multi-point display, and provide temperature rise detection and galvanic couple state judgment 6.
