4-20mA Explosion-Proof Temperature Transmitter and Customized for
Specific Needs Armored explosion-proof thermocouple summary: ·The protection tube and the measuring element are of a separate
structure, which can quickly replace the temperature measuring
element and carry out emergency repairs without stopping. ·Various
types and materials of protection tubes can meet the temperature
measurement needs of high pressure, high temperature and strong
corrosive media. ·The bottom of the temperature measuring core and
the protection tube are compressed by springs, which not only
reduces the thermal inertia but also improves the shockproof
performance. ·Using armored components, it is pressure-resistant,
shock-resistant, and works stably and reliably. ·Explosion-proof
mark: dⅡBT6, dⅡCT6 (without acetylene) and iaⅡCT6, suitable for
temperature measurement below grade Ⅱ, temperature group is T1~T6,
containing explosive gas. Technical Features and Specifications: This series of products conform to national standards GB3836.1,
GB3836.2, GB3836.4, and are designed and manufactured according to
relevant regulations and requirements in explosion-proof standards.
2001 standard, and has been approved by the National
Explosion-proof Electrical Product Quality Supervision and
Inspection Center and the National Instrument and Meter
Explosion-proof Safety Supervision and Inspection Station, and
obtained the explosion-proof certificate. When choosing an
explosion-proof grade, please note that the temperature group must
correspond to the highest temperature on the surface of the
installation site.
