S.O.S. was initially utilised in the advancement of high temperature integrated circuits for the NASA space programme. ESI has taken this technology and developed a sensor that is capable of accurately measuring vibration, torque, force or pressure in extreme temperatures over long periods of time.

The outstanding elastic properties of the sapphire substrate provide the perfect platform on which to create a sensor with no measurable hysteresis and superb repeatability. The excellent insulation properties of the sapphire protect the strain gauge from electro-magnetic pulse radiation, and allow the sensor to operate over a very wide temperature range without loss of performance.

Both transducers and transmitters convert energy from one form to another and give an output signal. The signal is directed to any device that interprets it and uses it to display record or alter the pressure in a system.

So how do you decide whether it is best to use a transducer or transmitter for you application? Transducers and transmitters are virtually the same thing, the main difference being the kind of electrical signal each sends. A transducer sends a signal in volts (V) or millivolt (mV) and a transmitter sends a signal in milliamps (mA). If the electrical connections in your process are short, such as in  laboratory or inside an electronics enclosure, a pressure transducer is more desirable as they tend to be smaller and there are very few active electronic components that can be upset by electromagnetic interference.

The Difference Between a Pressure Transducer and Transmitter

If you want to run the electrical output signal over larger distances, you would require a transmitter which is basically a transducer with extra electronics to amplify the signal. Many types of amplified signals have been developed over the years, but the two wire, 4-20mA current output has long been accepted worldwide as the main method of transmitting pressure transducer signals over longer distances. Apart from sending signals over increased distances, another benefit of a transmitter is that it incorporates zero and span adjustment potentiometers for easy calibration.

Ellison Sensors offers a wide range of transducers and transmitters for use in a broad spectrum of applications.

What is the difference between a pressure transducer and pressure transmitter?

Explosive atmospheres can be caused by flammable gases, mists, vapours or combustible dusts. If there is enough of the substance mixed with the air, one source of ignition can cause an explosion, leading to major damage, serious injury and even loss of life. Using the correct intrinsically safe equipment is a significant factor in the prevention of such explosions.

Excellent Performance Hazardous Zones

ATEX is the name commonly given to the framework for controlling explosive atmospheres. The regulations apply to all equipment intended for use in hazardous zones whether mechanical or electrical, and all protective systems. Intrinsic safety equipment must be tested and approved by an independent body to assure its safety. It involves a detailed process of examination, testing and assessment of equipment, with the end result being the issue of an ATEX certificate and report confirming that the product is safe to use within potentially explosive environments.

ESI now has an extensive range of intrinsically safe Silicon-on-Sapphire pressure transmitters, all ATEX approved to EEXIA IIC T4 standards by SIRA- a world leader in the conformity assessments field.

Silicon on Saphire Technology

Silicon-on-Sapphire (S.O.S.) technology was initially utilised in the advancement of high temperature integrated circuits for the NASA space programme. ESI has taken this technology and developed a sensor that is capable of accurately measuring vibration, torque, force or pressure in extreme temperatures over long periods of time. The big advantage of an S.O.S. sensor over conventional silicon based sensors is that it is free from residual stresses caused during processing which can lead to reduced performance. The excellent elasticity of the sapphire is a very important factor. The ability to bend the wafer and bring it back down to its original position- known as repeatability- is a highly desirable characteristic for sensors.

Incorporating SOS into applications where ATEX approval is required offers a reliable and durable solution with unbeatable performance and value. The range includes absolute, differential, submersible, high pressure, high accuracy, hygienic and rugged oil & gas transmitters.

Over the years, pressure transducers have provided a convenient, accurate and reliable method of controlling and monitoring pressure in thousands of applications, as well as being used indirectly to measure variables such as fluid/gas, water level, flow and speed.

What is a Pressure Transducer?

Pressure transducers are designed to be rugged and stable. They are able to operate in severe shock and vibration environments as well as a wide variety of media, and can therefore be installed directly at the point of measurement. The transducer is installed into the system by means of a pressure port which provides a mechanical interface to the process. This is usually an internal or external threaded connection, most common is the ¼’’BSP (or G1/4’’). The media travels through the port to the sensing element which consists of a silicon, foil or thin film strain gauge mounted on to a metal or ceramic diaphragm. The sensor is powered by voltage excitation and as the diaphragm deflects under applied pressure, the resistance of the strain gauge changes giving a ratio metric electrical output.

The sensor is usually housed in a metal body which provides environmental protection and is sealed by an electrical connection, most commonly the DIN 43650 plug and socket. The electrical connection provides the means to power the sensor and convey the output signal. By attaching an amplifier to the sensor, the low level signal can be converted to either an increased voltage output or a current output. This enables easy integration into process and control systems requiring modular inputs and can be transmitted over far greater distances.

There have been many different types of pressure transducer developed over the years, and they vary dramatically in technology, design, performance and cost. Ellison sensors have a wide range of products to suit a broad spectrum of applications.
