Transducers generally convert energy from one form to another, although the energy is typically a signal. They are routinely used in automated systems, which are often controlled by measurements of physical quantities such as force, motion, temperature and pressure. A sensor is a specific type of transducer that senses a physical property of its environment and reports that change, typically in the form of an electrical signal. For example, a pressure sensor detects pressure and reports it to a gauge that displays the pressure.

With the rise in smart watches and navigation systems, absolute pressure sensors find homes wherever elevation above sea level (altimeter measurement) is required. Weather stations also use them for barometric pressure measurements.

Physical separation from hazardous media: Fluid-isolation barrier can be implemented to prevent corrosive media coming into direct contact with the sensor diaphragm; Heat is dissipated from the media in the tube.

Pressure sensors for use with corrosive media often feature housings made from stainless steel or plastics such as PVDF, PVC or PPS. TM Sensor use a stainless steel diaphragm backed by silicon oil that transfers pressure to the sensing element.

Tips show how a Milli voltage-output pressure sensor, Voltage-output pressure transducer or Current-output pressure transmitter be connected to a programmable logic controller (PLC) or meter to monitor pressure in a typical industrial equipment or process control application.

Industrial pressure sensors also referred to as pressure transducers, pressure transmitters, pressure indicators and pressure switches, normally have a diaphragm type design that uses strain gauges, which are either bonded to or diffused into it, with the strain gauges acting as resistive elements.

Terms of pressure sensor, pressure transducer and pressure transmitter are somewhat interchangeable in the industrial world. Pressure sensors can be described with a 4-20mA output signal and pressure transducers with a millivolt signal.

How to select the appropriate sensor When we provide sensing solutions, it is very important to choose the right products. There are so many kinds of sensors. Once the selection is not good, it will bring a lot of issues to the application.

How to select a suitable pressure sensor sometimes is a difficult decision. There are some tips for you. There are six common types of pressure sensor in our market, it's hard to say which one is best, but we can select a most suitable once upon our application and practical condition. we have a table to analyze their different performance and features.
