00:07 PROTECT THE SENSOR DIAPHRAGM
First of all, you want to make sure that you don’t let anything hit the diaphragm. A sharp impact can cause drift so I would suggest that you keep the cap on until you’re ready to install the sensor.

00:18 SEALING THE PRESSURE TRANSDUCER THREADS
Start by sealing your threads.

00:20 Sealing Tapered Threads
For tapered threads, use teflon thread tape or a sealant compound. You only need about 3-5 wraps to seal the sensor. This is because you can gum up your threads if it is too thick and if it is too thin you’re not going to get a very good seal.

When you’re sealing the threads you’ll want to wrap the tape in the opposite direction of the thread. This is to avoid unravelling the tape as you screw on the sensor.

00:41 Sealing Straight Threads
If you’re using a straight threaded sensor the o-ring should create a good enough seal. So be sure not to rely on thread tape to seal straight threads.

00:49 TIGHTENING THE PRESSURE TRANSMITTER
A flush mount diaphragm is pretty sensitive to over torquing so you’ll want to refer to your user manual for a torque spec.

00:56 Tightening Tapered Threads
If you’re installing a tapered thread, tighten it as little as possible to get a good seal.

01:00 And that is how you properly install your threaded pressure sensor.
