Ask for the model of the instrument connector in the photo

1. What model is this instrument connector? 2. What model of instrument connector is this? 3. What model is this instrument connector? 4. What model of instrument connector is this? This cable gland is composed of several parts; only the label DQM-VII NPT 1/2B can be seen on it. What is the specification of the connecting part in the middle?
For non-outgoing NPT and ferrule types, it depends on the specific markings.
No model number was found on the connector, so I’m asking.
Take it apart and show it to someone experienced. For the first diagram, look at the instrument interface diagram; it will be there.
Measure the threads, measure the pipe diameter,… Once you’ve measured them, write down the model number yourself :lol {:2_36:}
For the cartridge tee, it’s best to measure the outer diameter of the steel pipe; it should be either 3/8 inch or 1/2 inch pipes
1、1/2\" NPT male and female elbow； In the diagram, the installation direction of the split-type temperature sensor is unreasonable, which results in the inlet port pointing vertically upward. To prevent the sensor from being installed in an upward orientation, a 90° threaded elbow was used. 2. Socket-type three-way union joint (PARKER) 3. Threaded union 4. 1/2\" NPT explosion-proof sealed joint (dual-seal Gland); it is a single unit and not purchased separately.
First, 1/2\" NPT connection; the pipe threads with elbows are added only when the installation is not proper. The second is the standard ferrule thread (choose between imperial or metric as appropriate). The third is the flexible coupling thread. The fourth is the explosion-proof flange.
If I were the owner, I wouldn’t approve of the installation methods shown in the first three diagrams; the elbow in the first diagram lacks an explosion-proof certification； For the second diagram, I only accept welding for the chemical processing equipment ； The process connection in the third diagram also uses flexible joints, which is absolutely not allowed.
