产品概述

In the field of oil, gas, chemical and other industries often accompanied by flammable, explosive, corrosion and other chemical gases, vapors and liquids, in order to automate industrial production, require temperature sensors to automate the process of measurement and control, and the use of aluminum Alloy flameproof junction box has been unable to meet the site explosion safety requirements.

Flameproof thermocouple, thermal resistance, explosion-proof qualified testing by the state-level safety supervision and inspection station and certification issued by the explosion-proof series of product certification.

It uses all stainless steel junction box for Exd Ⅱ CT1 ~ 6 and requires the highest level of protection to IP65 with a corrosive and explosive atmosphere of the place.
