Handheld Thermocouple Calibrator for Steelmaking

Translation: Original

Overview
LGK-JS02-064 handheld thermocouple calibrator (referred to as thermocouple calibrator). The calibrator is specially used for thermocouple temperature measurement. It has built-in 2 high-precision and high-stability thermocouple temperature conversion chips, which can measure the temperature data of two-way thermocouples at the same time. It is mainly used to detect whether the function of the thermocouple is normal before and after use. The product design takes into account its application in industrial field, and the calibrator has been optimized in terms of stability, reliability and anti-interference, and can be applied to various complex working conditions. The appearance design of the calibrator strengthens the design of resistance to falling and oil stains. The overall calibrator is easy to use, intuitive to display, small and portable, stable and durable, and easy to operate.

Working principle
The LGK-JS02-064 handheld thermocouple calibrator adopts a special industrial chip for thermocouple temperature acquisition, reads the temperature data of the thermocouple sensor at a single point, and then processes the data through an industrial-grade low-power single-chip microcomputer, and then passes the digital tube displayed on the screen.

Composition
As shown in the figure, the device uses a self-locking metal button switch for switching on and off. The calibrator comes with a lighting design, which is mainly used for thermocouple maintenance with the poor light in the operating environment. The design fully considers the actual needs of field applications, and the design is very humanized and rational. The temperature data is displayed through a bright red digital tube, which is intuitive and convenient to check.
When using the thermocouple calibrator, we need to connect the thermocouples in the unpowered state. The T1 interface is a group, and the T2 interface is a group. Make sure the connection is good. Press the switch, and the thermocouple calibrator will directly display the temperature of the thermocouple in real time.
