View A Video on Pressure Transducers - A Quick Introduction

Pressure transducers are devices that convert any physical force being exerted on them into electrical energy. In the simplest and most general definition, a transducer is any device that converts energy from one form to another. Pressure transducers take energy gained from pressure and convert that energy into electricity. Transducers are key components in pressure sensors (also called pressure transmitters), and though the terms are frequently used interchangeably, a pressure transducer is technically just one part of a pressure sensor.

Despite the imprecision of the label, the term "pressure transducer" can be used to describe a pressure sensor without creating much confusion, mostly because pressure transducers are applied almost exclusively as pressure sensors. Miniature sensors, pressure calibrators, pressure regulators, level transmitters and other pressure sensor varieties all require the use of pressure transducers to measure and report pressure levels in an area. Temperature transducers and torque transducers are also somewhat imprecisely named, but that imprecision does not typically cause confusion; they are also used to convert input energy into electrical energy for the purposes of measurement. Air pressure sensors are among the most common pressure sensors. The three main air pressure sensor categories, absolute pressure sensors, atmospheric pressure sensors and differential pressure sensors, distinguish themselves from each other based on how they measure air pressure relative to ambient pressure.

There are numerous varieties of pressure sensors, and they are classified according to the range of pressure they measure, the operating temperature range and the kind of pressure they measure. The five main categories of pressure sensors include absolute and differential sensors as well as gauge, vacuum and sealed pressure sensors. Absolute pressure is measured against a perfect vacuum, which is 0 pounds per square inch (PSI). Atmospheric pressure, for example, is ~14.7 PSI at sea level as measured by an absolute pressure sensor. An air pressure sensor determines the pressure of air flow and provides a convenient and accessible way to understand the reading. These sensors are typically used with air compressors or pneumatic tools. Barometric or atmospheric pressure sensors provide readings of the pressure from the so-called weight of the air and are frequently used in meteorology. Differential pressure sensors calculate the difference between two or more pressures as measured by various inputs in the unit. They measure drops in pressure and the rate of flow within enclosed or pressurized vessels. Miniature sensors are designed for use in critical medical or biological applications where instruments should provide a very low intrusion volume.

There are many different devices used to measure and describe pressure, and they are frequently combined into one mechanism or device that maximizes the information it provides. Pressure calibrators are devices that measure and report the pressure, level and flow of certain instruments in order to keep them operating safely and efficiently. They receive input from an established system and compare that information with what the system's gauge reads, allowing the operator to quickly determine whether the gauge is reading correctly or not. This is an important step in maintaining safe conditions. Pressure regulators monitor and control the amount of pressure running through a system. Typically they can be programmed to alert operators if the pressure exceeds a certain point in order to maintain safe conditions. Pressure is affected by a number of variables and therefore measured in a range of ways. The level of a solid, liquid or slurry in a specified space is measured by level transmitters that usually provide feedback in the form of an alarm or shut-off switch. Temperature transducers and torque transducers measure additional information such as heat content and rotational movement. To measure temperature, the sensor can be placed directly in the substance and measure its own temperature, or it can make a reading based on thermal radiation. Torque transmitters measure the twist in a rotating system, both static and dynamic.

Transducers, sensors and transmitters have been necessary since the Steam Age and have made substantial improvements since then. Advancements in materials and technology have allowed sensors and transducers to become smaller and more accurate. Modern materials include ceramic, copper, stainless steel and various other metals. For example, a typical pressure sensor is about a cubic inch in size but miniature sensors can be less than 1/100th that size. Most are accurate with less than one percent margin of error. They are used in critical situations and are kept reliable through proper calibration and backup systems. The integrated circuit, also known as an IC, microchip or silicon chip, is a miniaturized electronic circuit that is used in almost all electronic equipment today. Many sensors and transducers use chips to maintain accuracy and to communicate with other equipment. Modern sensors work based on the principle of piezoresistance, which is the observation that various amounts of pressure cause a material to conduct electricity at certain rates. The transducer receives the force from pressure and converts it to electrical energy. The charge is fed to a wire that reads it and can determine the pressure that was applied; a sensor then reads the information and displays it in a readable way.

Pressure Transducer Types

  • Absolute pressure sensors measure pressure regardless of ambient pressure conditions; in other words, absolute pressure sensors measure pressure in reference to an absolute vacuum as opposed to in reference to ambient air pressure.
  • Air pressure sensors measure the force of air exerted on the device and then convert the information into a readable display.
  • Atmospheric pressure sensors measure the force exerted by the weight of air and convert the information from electrical energy to a readable display. 
  • Differential pressure transducers are instruments that detect fluid pressure and produce an electrical, mechanical, or pneumatic signal in response to the pressure.
  • Level transmitters are devices that measure the level of a solid, liquid or slurry within a container then convert the information into a comprehensible form.
  • Miniature pressure sensors are designed to unobtrusively measure the pressure of gases or liquids and then display the results in an understandable way.
  • Pressure calibrators are devices that determine how accurately sensors are measuring pressure in order to keep them operating safely and efficiently.
  • Pressure regulators monitor and control the pressure of gas and liquid passing through a system by opening and closing valves in order to match the flow of the fluid to the demand for it.
  • General-purpose transducers for the purposes of pressure measurement perform well for a wide range of electronic pressure measurement applications. They have a high-accuracy rate.
  • Industrial grade transducers for the purposes of pressure measurement fit most industrial pressure measurement applications. The printed circuit board is potted in silicone gel for protection against shock, vibration and humidity and uses state of the art surface mount technology.
  • Pressure sensors are used to measure the pressure of gases or fluids. They are designed to monitor changes in pressure and are often connected to safety devices that activate shut-off switches. Pressure sensors use their pressure readings to send a message to another mechanism.
  • Pressure transmitters are used to measure, monitor, and transmit the pressure of liquids or gases.
  • Strain-gage base transducers convert pressure into an electrical signal by physically deforming strain gages, which are bonded into the diaphragm of the pressure transducer. This introduces strain to the gages, which then will produce an electrical resistance change proportional to the pressure.
  • Submersible liquid level transmitters and transducers are specifically designed for municipal liquid level measurements and a range of other applications. Specifically, these transducers are used for water and wastewater treatments, well depth measurements and offshore water depth measurements and therefore use a watertight, high-strength vented polyurethane cable, which is capable of complete submersion.
  • Temperature transducers are devices that change an input of energy into a temperature reading.
  • Torque transducers are instruments that measure torque on rotating systems.
  • Transducers are devices that convert one type of energy into a different output form.

Pressure Transducers Terms
