A very common output signal for sensors of all kinds, 4-20mA has a few very good reasons why it has been so popular for so long:
Long Cable Runs
The 4-20mA output allows for cable runs over 1000 ft. with almost no signal degradation and without regard to any voltage drops in the wire.
Our design engineers and tech support team has heard and seen just about everything when it comes to level sensors and pressure transducers. Today, we want to cover the top ten things to NOT do with a pressure sensor.
The order of this list was determined based on two factors: frequency of the mistake, and the seriousness of the offense.
A slight customization we did for a customer quite a while ago has become more popular recently: putting a cable between the actual pressure transducer and the digital display on a digital pressure gauge.
When repairing or loading aircraft, weight distribution and balance are paramount. Measurements have to be taken from several points to make sure proper balance is maintained, and the aircraft can fly safely and efficiently.
Part 2 of our series on data logging with the PG10 digital pressure gauge covers data logging based on the sample rate. This allows you to take consistent samples at predefined intervals. Check out the video below:
Pressure sensors and digital pressure gauges are often subject to large fluctuations in temperature which can lead to decreased accuracy. In applications where maintaining high standards of accuracy is a must, this effect can lead to major issues.
Then you're in luck. The PG10 digital pressure gauge let's you do just that. Currently, we can log the latest 60 readings on the actual gauge. (In the near future, we'll be able to connect the gauge to a computer and log continuously for as long as needed. We're validating that software now. Drop us a line if that sounds interesting to you.)
There are many who use one of our digital pressures gauges to measure pounds of force in a hydraulic system. This is done by converting PSI to LBS in the custom multiplier menu on the gauge. Once this is done, the pre-existing load in the hydraulics must be cancelled out before taking the critical measurement. Watch the video below to learn more:
