Normally, pressure transmitters are used to determine pressure of liquids or gases. This pressure is the power that's needed is to stop either a gas or maybe liquid from increasing. Normally referred to as pressure sensors, the devices generate electric useful signs which indicate the level of pressure imposed.

Pressure transmitters are extensively used in diverse applications for controlling and monitoring pressure. They're extensively used to determine water levels, altitude, gas/liquid flow and also speed amidst other crucial pressure measurements. Still, not all the pressure transmitters are the same. They are different in design, technology and also performance. Which means different pressure transmitters are simply made for certain applications. Here are some of the different types of pressure transmitters available:

* Absolute transmitter - This sort id designed to determine pressure relative to best vacuum conditions.

* Gauge transmitter - This is one of the most common forms of pressure transmitters available. A perfect example is the tire pressure gauge. A gauge pressure transmitter ...
... is used to determine pressure relative to atmospheric pressure.

* Vacuum transmitter - This sort of pressure transmitter can be used to determine pressure under atmospheric pressure and also absolute pressure.

* Sealed transmitter - Although this type is a lot like gauge transmitter, it is simply ideal for computing pressure relative to fixed pressure.

* Differential transmitter - This kind is used to measure the difference between two pressures.

Of all the above types, it's the differential pressure transmitter that differs tremendously from the others. It should however be noted that the above are not the simply sorts of pressure transmitters available. There are many other types whose difference generally is in the technology used.

The DP pressure transmitter

It's a form of pressure transmitter which is designed to determine pressure in two different environments. It's the transmitter of choice when it comes to computing pressure declines in air filters, fluid levels and also changes in pressure when a liquid or gas flows. To provide correct pressure readings, calibration of a DP pressure transmitter is extremely crucial. The temperature calibration method is however simple and straight forward.

The 1st step for calibrating a DP pressure transmitter starts with filling up two columns of the transmitter with a liquid. The two columns are afterwards connected and normally have a level transmitter on the column. The calibration method requires calibrating the level transmitters, setting one column at zero level and also the other at 100 percent. While setting one column at zero means setting the level of the liquid to be even with that of the transmitter, setting the other column at 100 percent is randomly since transmitter measures pressure change in relation to the other column.

Besides the above mentioned method over, calibration of a DP pressure transmitter is not yet over. What follows is the multiplication of the liquid height by the liquid/gass gravity just before re-calibrating the transmitter to the new liquid column height. This yields pressure in one particular column. It is simply after this that the DP pressure transmitter can be prepared to take pressure measurements.
