Seeking help regarding the explosion-proof connection method for Yokogawa differential pressure transmitters
Thread Content
The instruments produced earlier were connected to the calculator in the explosion-proof box, which housed several transmitters, using explosion-proof flexible hoses. Since installing such flexible hoses is inconvenient and costly, I’m turning to this versatile forum to find a convenient, cost-effective, and aesthetically pleasing way for explosion-proof connections: handshake
First of all, for the cables, they should at least be intrinsically safe armored cables; for the junction boxes and meters, explosion-proof armored gland connectors will suffice
It seems that explosion protection is not supported, and the specifications of the wiring are not suitable for connecting to the transmitter
Flexible pipes are very cheap; it’s not costly at all, and explosion-proof connectors can be added to them.
I agree with the method from the second floor; other methods will also work, but you mentioned first that explosion-proof flexible pipes are rigid, so the solution proposed in the second floor is the correct one
Add gland heads on both sides. Only after maintaining it myself did I realize how troublesome flexible hoses are; when the cable is a bit short and cannot be pulled, it’s very inconvenient to connect it to the meter.
