30 PSI-G-DO Datasheet/PDFPressure sensors, transducers and PSI-G-DOs are a crucial part of modern day technology. Pressure sensors measure the force of a physical pressure, and are used in a variety of industries such as automotive, medical, manufacturing, and aerospace. Pressure transducers are a type of pressure sensor which converts a pressure signal into an electrical signal, whereas PSI-G-DOs, or Pressure Switch Input Gauge Digital Output transducers, are a type of pressure transducer which can switch a digital output when a pre-determined pressure is reached. This article discusses the application field and working principles of PSI-G-DO transducers.
PSI-G-DOs are designed to provide accurate measurements of dynamic pressure ranges. Their primary application field is in safety systems where they are used as limit switches. For example, in automotive applications, a PSI-G-DO transducer could be used to monitor the pressure in a braking system, with the device switching a digital output when the set pressure is exceeded. This could alert the system to possible issues, such as a faulty brake or low fluid level. PSI-G-DOs are also used in industrial processes, such as in tanks and pipelines where their accuracy is invaluable in detecting pressure peaks which could cause damage.
The working principle of PSI-G-DO transducers is based on the principles of strain gauges and Wheatstone bridges. When pressure is applied to the sensor, the diaphragm of the transducer deforms, changing the electrical resistance of the strain gauges. This change in resistance is detected by an internal Wheatstone bridge, and transformed into a suitable electrical signal. This signal is then amplified before it is passed through an analog-to-digital converter, which increases the current while converting the analog signal into a digital signal. This signal is compared to a pre-set limit, and when the preset limit is exceeded, the transducer switches the digital output.
In conclusion, PSI-G-DOs are an important type of pressure sensor which can be used for safety systems and industrial processes. They are based on the principles of strain gauges and Wheatstone bridges, and measure dynamic pressure ranges while switching a digital output when the preset pressure is exceeded. Their accuracy makes them invaluable in detecting pressure peaks which could cause damage.PSI-G-DOs offer designers accurate and dependable solutions in a range of industries, and their applications are only set to increase in the near future.
