Скачать или смотреть How To Re-Zero The PT-500 Submersible Pressure Transducer

APG's PT-500 submersible pressure transducer is the only submersible pressure transducer on the market with a field-adjustable zero. This let's you correct your sensor as it naturally drifts over time.

All you need is a magnet (supplied) and you can move your zero up or down. It's that easy!

We are going to show you how this is done.

00:19 SENSOR READING IN TANK BEFORE RE ZERO
We have a small tank with 20 inches of water. At this depth, our output should read 5 milliamps. But, you‚'ll notice our sensor is incorrect.

00:29 HOW TO RE ZERO YOUR SENSOR
So we'll simply pull our sensor out of the tank and use our magnet to adjust the zero back to 4 milliamps. If you hold the magnet near the middle of the sensor, it moves the zero up. If you hold the magnet near the bottom of the sensor, it moves the zero down.

00:42 PLACE BACK IN TANK
Once your sensor is properly adjusted, lower it back in the tank.

All finished! It's quick, it's easy, and you'll only find it on the PT-500 submersible pressure sensor from APG.
