Types of transmitter models
Pressure transmitters are used in various industrial fields and depending on the signal they produce, they are also known as pressure converters or transmitters. These instruments work by measuring pressure through a flexible component, then converting the amount of flex to a measurable electrical signal.
Transmitters are designed based on the size and complexity of the system and reflect different forms of pressure reading including absolute pressure, gauge and pressure differential.
To help you evaluate different brands of transmitters, we have collected information about some of the top transmitter manufacturers.
Vega Transmitters (VEGA) Pressure measurement techniques can be used to measure process pressure or differential pressure as well as surface, volume, density or flow in all parts of the technology process.
Measurement ranges in Vega pressure transmitters start from a few millibars and continue up to high pressures up to 1000 bar. Various parts have been used to measure pressure in this instrument.
Vega pressure transmitters provide high-precision readings of gases, vapors, and liquids.
A special advantage of Vega is that the status display has a 360 degree change of position. Thanks to the 360-degree mode change display, all switching modes are recognizable from any direction. The color of the bright ring is clearly visible even in daylight. You can also easily choose one of more than 256 colors.
At a glance it can be seen whether the pressure measurement process is running? Is the sensor changing? If there is a possible error in the work process, it will be determined.
Also, the new VEGABAR series pressure switches are perfectly suited for standard applications.
Adjusting the function of this transmitter is possible through a smartphone. Designed hygienically and sterile. Easy integration is possible thanks to IO-Link.

Honeywell ( HONEYWELL )
Honeywell pressure transmitters are a powerful device ideal for use with WECO 1502 connectors. These devices are known as Hammer Union pressure transmitters. The Model 427 (BFSL ۲ 0.2) ensures a smooth flow of the instrument cluster using a wider, shallower measuring port. This model is suitable for land and sea applications for oil and gas exploration and drilling.
Model 427 helps detect pressure changes by providing accurate and reliable data. This feature allows the operator to adjust the flow pressure during drilling. It also helps drilling operators better manage oil spills. Thus, the safety of operators is increased by analyzing potential hazards such as gas bubbles. The use of the honeywell model 425 transmitter is almost the same as the 427 model. This model is offered in two levels of accuracy, Best Straight Line (BFSL) and High Accuracy (BFSL-High Accuracy). Model 425 is designed and built for harsh conditions in onshore or offshore drilling and for use in the gas and oil industries as well as in drilling applications. These stainless steel transmitters are made of fully welded sealing. For this reason, they provide reliable and accurate data for detecting pressure changes.

The last word
While pressure sensors can detect pressure changes by converting changes in resistors or capacitors to electrical values, these electrical signals are relatively weak. These signals are not strong enough to be transmitted at other distances, or to a controller that may be far away from the pressure sensor. A pressure transmitter is needed to achieve this goal . A pressure transmitter includes a pressure sensor plus a conditioner signal to amplify the output of the pressure sensor. Pressure transmitters usually have a display that shows the amount of pressure transmitted by the pressure sensor and converted to a standard output. This output is usually 4 to 20 mA or a digital signal.
