WRER-15 WRER2-15 Chemical thermocouple

Overview

The standard of WRER-15 WRER2-15 Chemical thermocouple complies with the regulations of JB/T5219—91 and JB/5583—91 thermocouple and thermal resistance; while the fixed flange meets the above standards, three different welding methods and fixed flange installation with different forms of sealing surface are added. Disk for selection and meet the needs of different users.

Working principle

The electrode of WRER-15  WRER2-15  Chemical thermocouple is composed of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential will be generated, and the working instrument will display the thermoelectric. The temperature value corresponding to the potential.

Features

WRER-15  WRER2-15  Chemical thermocouple adopts a waterproof junction box, which is suitable for the environmental requirements of petrochemical industry. The standard of the fixed thread meets the requirements of JB/T5219-91 and JB/5583-91 thermocouple and thermal resistance; the fixed flange meets the above standards at the same time. Three different welding methods and different types of fixed flange mounting plates with sealing surfaces are available for selection and meet the needs of different users

Main tech data

The test voltage of insulation resistance at room temperature is DC 500V. The atmospheric conditions for measuring the insulation resistance at room temperature are: temperature 15～35℃, relative temperature 45%, atmospheric pressure 86～106kpa.

For a thermocouple with a length of more than 1 meter, the product of its normal temperature insulation resistance value and its length should not be less than 100MΩ·m
