Specialized Sensors: CRD 5110-150-5 Application Field and Working Principle

Pressure sensing is a crucial element in both industrial and consumer applications. If a device or system is expected to be consistently accurate and reliable, it is essential to accurately measure the pressure applied to it. The CRD 5110-150-5 is a pressure transducer that offers high accuracy and durability, making it well suited for a variety of applications. This article will discuss the application field of the CRD 5110-150-5 as well as its working principle.

Application Field

The CRD 5110-150-5 is a piezoresistive pressure transducer that measures pressure in the range of 0-150 PSI gauge. This makes it ideal for a wide range of applications, including industrial process controls, pump and safety systems, hydraulic or pneumatic system controls, automotive, as well as laboratory and medical equipment. The device is available in both AC and DC configurations and offers a long-term stability of less than 0.05% full-scale accuracy, making it an excellent choice for applications that require precise, repeatable measurements.

Working Principle

The CRD 5110-150-5 uses semiconductor piezoresistors, also known as strain gauges, to measure pressure. Semiconductor piezoresistors are small pieces of semiconductor material embedded in a special polymer matrix. When the material is stretched or compressed, a change in its electrical resistance can be measured. This change is proportional to the pressure applied. The CRD 5110-150-5 uses a Wheatstone bridge circuit to measure this change in resistance. The bridge has four resistors, one of which is the strain gauge that senses the pressure applied. When pressure is applied to the strain gauge, its resistance changes and the bridge circuit is unbalanced. This produces an output voltage that is proportional to the applied pressure. The output voltage can then be read by any device or system designed to read it, such as a data acquisition system or analog-to-digital converter.

Conclusion

The CRD 5110-150-5 is a specialized pressure transducer that offers high accuracy and reliability. It is well suited for a wide range of industrial and consumer pressure sensing applications. The device uses semiconductor piezoresistors to measure pressure and a Wheatstone bridge circuit to measure the change in resistance. This device is capable of providing accurate and repeatable measurements and is thus an invaluable tool for pressure sensing applications.
