SDX100D4

Pressure sensors and transducers are an essential component in a variety of industrial and consumer products. From detecting pressure leaks in water pipes to controlling the temperature of a liquid in a steam boiler, pressure sensors and transducers are used to measure changes in pressure and convert these changes into a recognizable electrical current or signal. The SDX100D4 is a hydrostatic pressure sensor designed to measure liquid level, liquid depth, and pressure of non-corrosive liquids.

Application Field

The SDX100D4 is a reliable and robust pressure sensor designed for general purpose applications, including water treatment and tank level measurement, semi-conductor processes, laboratory pressure tests, and ABS/Brake systems. The SDX100D4 is capable of operating in a range of temperatures from -20°C to 85°C, making it suitable for applications in most climates. Specifically designed to measure the depth and pressure of clean, non-corrosive, non-turbulent liquids with a maximum pressure rating of 400bar / 5800psi.

Working Principle

The SDX100D4 is a transducer that utilizes the Wheatstone bridge principle to measure pressure. The Wheatstone bridge works by having four resistors arranged in a Wheatstone V-shaped formation. The bridge measures the difference in voltage between two resistors and uses this to gain information about the resistance of the sample being tested. The SDX100D4 measures pressure by applying an excitation voltage to the Wheatstone bridge. The resistance of the two fixed resistors in the bridge stays the same, while the resistance of the variable resistors changes depending on the pressure being applied to them. The SDX100D4 then takes the difference between the two fixed resistors and the variable resistors to give a signal corresponding to the pressure being applied.

Conclusion

The SDX100D4 is a reliable and versatile hydrostatic pressure sensor designed for general purpose applications. This pressure transducer uses the Wheatstone bridge principle to measure pressure in non-corrosive liquids and accurately convert the pressure value into a recognizable electrical signal. The SDX100D4 features a maximum pressure rating of 400bar / 5800psi and is capable of functioning in a wide range of temperatures, making it suitable for a variety of industrial and consumer applications.
