How To Install A Threaded Pressure Transducer


It's all too easy to wear out threads if you're not careful. This tutorial will show you how to install a pressure transducer to protect the threads and the sensitive diaphragm. They may be built for tough environments, but at the end of the day, the diaphragm and threads are critical enough to handle with care.

Narrator: Thanks for purchasing an APG pressure sensor! In this video we’ll cover the steps to installing it properly.

First of all, you wanna make sure you don’t let anything hit the diaphragm. A sharp impact can cause drift, so I would suggest you keep the cap on until you’re ready to install the sensor.

Step 1: Okay. Start by sealing the threads. For tapered threads, use Teflon thread tape or a sealant compound.

You only need about three to five wraps to seal the sensor. This is because you can gum up your threads if it’s too thick, and if it’s too thin, you won’t get a very good seal.

When you’re sealing the threads, you will want to wrap the tape in the opposite direction of the thread. This is to avoid un-raveling the tape as you screw in the sensor.

If you are using a straight threaded sensor, the O-ring will create a good enough seal. Be sure not to rely on thread tape to seal straight threads.

Step 2: So start by screwing the sensor in by hand until you can’t twist anymore. Then use a wrench to finish the job.

If you’re installing a straight thread, you should stop when the sensor stops, or bottoms out. A flush mount diaphragm is pretty sensitive to over-torqueing, so you’re gonna want to refer to your user manual for a torque spec. If you’re installing a tapered thread, tighten it as little as possible to get a good seal.

And that is how you properly install your threaded pressure sensor. Thanks for watching!
