How to connect explosion-proof sensors to wire conduit pipes
Thread Content
An electronic scale has 4 sensors. The main cable enters the explosion-proof junction box through a conduit pipe; the junction box has 4 cable outlets with G1/2 threads. The sensor cables have external threads, and the manufacturer of the explosion-proof hoses said that these threads are too small to use for such connections. How should the sensors be connected to the junction box? I would be very grateful if experienced experts could share their insights. Thank you so much
Hello! The original poster – G1/2 can do it; ask other manufacturers. You can refer to the content below. ----NGd – Explosion-proof flexible connection tubes, Class IIB, IIC – For areas at risk from explosive gas mixtures: Zones 1 and 2. Flammable gas/vapor classes: IIA, IIB, IIC. Temperature groups: T1–T6. Suitable for use indoors and outdoors, for connecting electrical equipment or in situations where it is difficult to bend steel pipes ； It features good flame resistance, oil resistance, corrosion resistance, aging resistance, flexibility, and a robust structure ； It can be customized according to user requirements. Examples are as follows: Model, Nominal pipe diameter, Thread, Length, Minimum bending radius, Explosion protection rating, Protection class. NGd-15x700□G1/2: 15, G1/2, 700, 80, DII BT6, IP54; NGd-20x700□G3/4: 20, G3/4, 700, 80, DII BT6, IP54
You can ask more about whether G1/2 is available for purchase, as I have bought it from Jack Ma’s store:lol:lol
Generally, the smallest fitting for explosion-proof hoses is G1/2", but it is possible to have the threads customized, or a reducer can be used as well. For example, one can purchase a hose with one end of size G1/2" (inner) and the other end of size G1/2" (outer), and then use a reducer with inner threads matching those of the G1/2" (outer) end.
