Introduction to Pressure Sensors, Transducers

Pressure sensors, transducers, are devices that measure and convert pressure into electrical signals. They are widely used in oil, gas, water, chemical, and food industries to monitor and control processes. Pressure sensors have been used to measure hydrostatic, hydrodynamic pressures, and other fluid pressures. They are typically calibrated in one of two ways: Either they can be set up to measure pressure relative to atmospheric pressure (gauge pressure) or they can be set as absolute pressure sensors and measure pressure relative to an absolute value (vacuum or absolute).

P51-200-G-D-I36-4.5OVP-000-000 Application Field and Working Principle

The P51-200-G-D-I36-4.5OVP-000-000 is a fully-featured digital pressure transducer with standard 0-200 psi range. It has a very low combined accuracy of 0.1%FS and hysteresis of 0.05%. It is ideal for high accuracy, low-pressure hydraulics applications and high accuracy medical and safety monitoring. It features an additional output of 0-4.5Vdc, where 0 Volts = 0 psi and 4.5 Volts = 200 psi. The output signal can be freely scaled. The product also has a built-in output temperature compensation and protection against overload current.

The working principle of the P51-200-G-D-I36-4.5OVP-000-000 pressure transducer is based on the Wheatstone bridge principle. In this circuit, two pairs of resistors are arranged in the form of a bridge which is connected to an electrical power source. The pressure is applied to the bridge in the form of a force and this results in a differential voltage across the bridge. The differential voltage is then converted to an electrical signal by the transducer and can then be processed for further measurement or control purposes.

The device is also equipped with an I2C digital interface for in-depth diagnosis and data retrieval. The current sensor is powered by 3.3Vdc, and the output signal (Vdc) can be read through the I2C interface. Using the I2C interface, data like calibration data, temperature compensation and linearity can also be read and written.

Conclusion

The P51-200-G-D-I36-4.5OVP-000-000 pressure transducer is a versatile and fully-featured pressure sensor that offers an output of 0-200 psi and 0-4.5Vdc output signal. It operates using the Wheatstone bridge principle and has built-in features such as temperature compensation and overload current protection. An I2C digital interface also enables further in-depth diagnosis and data retrieval.
