Product introduction

WR series of industrial assembly type thermocouple as the measurement of the temperature sensor, Usually and display instrument, Recording instrument and electronic supporting the use of regulator. It can directly measure the various production process from 0C~1800℃range Liquid, steam and gas and solid medium surface temperature.

According to the provisions of the state, Our company in line with the IEC international standard index number Platinum and rhodium30-Platinum and rhodium6、Platinum and rhodium10- Platinum、Nickel chromium - nickel silicon, Nickel - chromium, Copper copper - nickel, Iron copper - Nickel Form.

Working principle

Thermocouple Working principle. Two different components of the conductor ends by welding, form loop, Direct temperature measuring end called the measuring end, The terminal end is called the reference terminal. When the measuring end and the reference end Temperature difference, Will be in the loop Thermal current, Connected to display instrument, The instrument will indicate the thermocouple Thermal electromotive force Corresponding temperature.

The thermocouple electromotive force with The measuring end temperature and growth, The size of thermal emf Only and thermocouple conductor material And the temperature difference between the two ends of the relevant, And the power electrode length, diameter.

Thermocouple assembly is mainly composed of a junction box, protection tube, insulating sleeve, terminals, power is the basic structure, And with a variety of mounting and fixing device (see below).
