Requirements for explosion-proof wiring
Thread Content
May I ask who has requirements for DIICT4b explosion-proof wiring? Connect to armored thermoresistors, transmitter.
It can be connected to an explosion-proof junction box, and the wiring method inside is very clear
There are no special requirements for the wiring; make sure that the inlet is properly sealed.
d Flameproof type II C for hydrogen; minimum ignition spark energy of 0.019 mJ. T4: safe object surface temperature ≤ 135°C. No special requirements for wiring, but due to the flameproof design, electrical connections (wiring terminals) must be properly sealed.
Just make sure it is waterproof and dustproof; generally, explosion-proof hoses are used to connect the instruments, with interfaces that are usually M20*1.5
5# cooldog_4412: You can refer to the HG28581 manual for automatic control installation. Generally, it is required that the electrical interface of the transmitter (usually 1/2NPT-F or M20*1.5-F) be connected using a gland seal; if it is an armored cable, it can be directly inserted into the cable tray. For unarmored cables, it is advisable to protect them with an explosion-proof flexible tube, and the same applies to platinum resistance thermometers.
First, figure out the partitioning, and then consider whether it should be explosion-proof, increased safety type, intrinsically safe, encapsulated, and so on
There are no particular requirements for the wiring in explosion-proof zones, but the sealing of the connectors must meet the same explosion-proof standards
