The term 121668-0102 is a reference to a type of device used in the engineering and manufacturing industries to measure and/or control the pressure of liquids and gases. This device is commonly referred to as a pressure transducer or pressure transducer/transmitter. While there exist several variations on the 121668-0102 design, they all generally serve the same purpose.

A 121668-0102 pressure transducer/transmitter consists of a core ceramic or piezoelectric element and various nearby components. As the pressure of the liquid or gas that the transducer is in contact with increases or decreases, the ceramic element reacts by expanding or contracting, in turn producing an electrical (e.g. voltage) signal. This signal, converted to a proportional pressure measurement, is then sent to a controller, recorder, or an indicator.

The 121668-0102 pressure transducer/transmitter derives its accuracy and repeatability from the precision of the ceramic element around which it is constructed. The precise location of the ceramic element within the pressure transducer/transmitter renders it particularly suited for high-accuracy subtraction applications. In other words, it can be used to accurately measure the difference between two pressure sources, e.g. an incoming pressure and a static reference pressure. Consequently, these types of pressure transducers are commonly used in instrumentation applications to measure a variety of properties in the medical, automotive, food, and aviation industries.

Essentially, the ceramic element composition and construction determines the level of accuracy of 121668-0102 pressure transducer/transmitters. This is why test and calibration equipment must be of incredibly high precision in order to ensure the accuracy of the pressure transducer/transmitter. This process is essential to ensure valid pressure readings given the fact that the actual work environment where the transducer/transmitter is to be used might differ from the laboratory environment in which it was calibrated.

In addition to its precision, many types of 121668-0102 pressure transducers/transmitters are designed with particular requirements in mind, such as operating temperature range, chemical resistance, or pressure media compatibility. This provides manufacturers, engineering, and product designers, an effective tool with which to enhance industrial safety and process control.

Pressure transducers/transmitters of the 121668-0102 variety come in many shapes and sizes. Depending on the application, they can be mounted on the wall, ceiling, or even suspended with cables. They can be built to withstand a wide range of temperatures, chemicals, vibrations, and other shocks that could be encountered in industrial settings. There are even specialized variations that are resistant to various temperatures and pressures and are able to cope with rugged environments and harsh conditions.

Regardless of the application, 121668-0102 pressure transducers/transmitters will result in accurate and repeatable measurements. This confidence in the accuracy of the pressure readings enables industrial designers and engineers to improve existing processes or develop new ones. Once pressure transducer/transmitters have been set up, industrial teams can concentrate their efforts on the quality of the products and/or the production process, instead of on individual pressure measurements.
