protection pipe and the measuring element is a separate type structure, can quickly change the temperature measuring element, don't stop to repair. · protection tube type and diverse materials, which can meet the high pressure, high temperature and strong corrosion medium temperature measurement needs. · temperature core and a protective tube at the bottom of the spring is compressed, can reduce the thermal inertia and improves the shockproof performance. The armoured element, pressure, seismic, stable and reliable work. · explosion-proof mark: D Ⅱ BT6, D Ⅱ CT6 (excluding acetylene) and IA Ⅱ CT6, suitable for level II, temperature classes for T1~T6, temperature measurement with explosive gas environment.
This series of products in line with national standards GB3836.1, GB3836.2, GB3836.4, according to the relevant provisions of the explosion-proof standards and requirements of the design and manufacture, the performance indicators in line with JB/T8622-1997, JB/T8623-1997, GB/T18404-2001 standards, and by the national explosion-proof electrical product quality supervision and inspection center and the National Instruments explosion-proof safety supervision and inspection station approval, obtain explosion-proof certificate. User note temperature groups must be on-site surface temperature and install the corresponding in the selection of explosion-proof level
