Pressure transmitters are electronic type pressure transducers, with Capacitive or diffused silicon sensors. Pressure transmitters, or called pressure transducers, convert pressure into an analog electrical signal. By connection, there are flush mount, tri clamp, and more. By output, there are analog, 4-20mA, 0-5V, and more. All pressure transmitters, with maniflod installation, can work for industrial tank. And, there more types pressure transmitters, like: differential pressure transmitter, submersible pressure sensor.

How does a pressure transmitter work?
The functional principle of a resistive pressure transmitter is very simple. The pressure sensor converts the mechanical pressure value into a proportional electrical signal. The pressure sensor typically consists of a stable main body and a (thin) diaphragm. The diaphragm is the most important element for the measurement of the pressure,and is equipped with strain-sensitive and compression-sensitive resistance structures, so-called strain gauges (DMS). The diaphragm is deflected under the influence of pressure. Thus, the strain gauges attached to it are elongated or compressed and its electrical resistance changes. This change in resistance is directly proportional to the pressure. For example, if the resistors are wired to a Wheatstone measuring bridge, the resulting electrical signal can be measured and transferred to an indicator.
What is the difference between pressure gauge and pressure transmitter?
Gauge Pressure Transmitters: Gauge pressure transmitters, which sense gauge pressure, are referenced to atmospheric conditions. Gauge transmitters are vented to atmospheric pressure rather than to an absolute vacuum. Gauge pressure transmitters are widely used in the process industries to measure the pressures of liquid, gas and steam. Both absolute and gauge pressure transmitters are growing in part by replacing pressure gauges, switches, and transducers. Pressure transmitters are more stable and reliable than pressure transducers. As end-users increasingly automate their operations and also build new plants, they are more likely to choose pressure transmitters over pressure transducers. Absolute and gauge pressure transmitters also have the advantage that, unlike differential pressure transmitters used for flow, they do not have another technology that is replacing them.
Pressure Transmitters While pressure sensors can detect variations in pressure by converting changes in resistance or capacitance to electrical values, these electrical signals are relatively weak. These signals are not strong enough to be transmitted over distances, or sent to a controller that may be located at a long distance from the pressure sensor. To accomplish this, a pressure transmitter is required. A pressure transmitter contains a pressure sensor plus a signal conditioner to amplify the output from the pressure sensor. Pressure transmitters also typically contain a display that shows the pressure value that is conveyed by the pressure sensor and converted into a standardized output. This output is typically either 4-20mA or a digital signal. There are four main types of pressure transmitters: absolute, gauge, differential pressure, and multivariable.
How do differential pressure transmitters work?
The most common and useful industrial pressure measuring instrument is the differential pressure transmitter. This equipment will sense the difference in pressure between two ports and produce an output signal with reference to a calibrated pressure range.
DPT series pressure transmitters represent the latest development in their class.
The digital sensor makes measuring pressure even more accurate than before.
Fully automated zero point calibration, AZ-calibration,
offers reliability in the most sensitive of applications.
Besides, it provides cost savings over the lifetime of a building,
as it makes the device completely maintenance free.
Applied pressure readings are acquired by the diaphragms, which register pressure as surface deformation, and translate that value into an electronic signal.This signal is transferred to the differential pressure module, which compares the two values and expresses the pressure difference, as a value of pounds per square inch (psi), bar, or kilopascals (kPa).These diaphragms are all-welded to maintain container integrity, in vacuum conditions and for wet leg applications, such as level measurement in crude oil distilleries.
What is pressure indicator transmitter?
Pressure indicator transmitters have a digital indicator for providing a local indication of pressure reading, and a 4-20 milliamp output pressure transmitter for sending an analogue signal to control & monitoring instrumentation. The built-in digital indicators can be scaled via push buttons or adjustment pots to any pressure unit or a 0-100% full scaling. No additional external supply is required, since the digital indicator is powered by the 4-20mA current loop from the pressure transmitter.
