SDP2000-L Application Field and Working Principle Pressure sensors and transducers are devices that measure either localized or dynamic pressures in either liquid or gas forms. The SDP2000-L is an example of such a device which is designed to measure a pressure differential. This article explores the application field and working principle of the SDP2000-L. The SDP2000-L is a differential pressure sensor that is capable of measuring pressures ranging between 0.3 to 4.5 psi. It requires an external pressure supply to measure the pressure differential, and it is usually employed in the following application fields:

• Hydraulic fluid pressure: the SDP2000-L can be used in hydraulic systems to measure pressure differentials in order to determine the force that is exerting on the items within the system.
• Air pressure measurement: the SDP2000-L is often used in air-systems to measure the air pressure at various points, such as within a filter system.
• Vacuum pressure: the SDP2000-L is also useful for measuring vacuum pressure within a sealed system.

The SDP2000-L is a transducer that is designed to perform a pressure measurement operation using a Wheatstone bridge circuit. A Wheatstone bridge consists of four resistors and a balancing voltage source. Depending on the design of the Wheatstone bridge, the SDP2000-L can measure either static pressures or dynamic pressures. The Wheatstone bridge works by applying a voltage to the resistors, which generates a small current. The current from the resistors is then measured and compared against a known reference. If the measured current is outside of the expected range, then the voltage source is adjusted until the current is within the expected range. Once the voltage is set, the Wheatstone bridge is said to have achieved its balance. The Wheatstone bridge is used in the SDP2000-L in order to detect and measure the pressure differential between two points. A voltage is applied to the Wheatstone bridge in order to generate a current, and the bridge is balanced by adjusting the voltage until the current is within the expected range. The voltage that is required to balance the bridge is proportional to the pressure differential that is being measured.In conclusion, the SDP2000-L is a differential pressure sensor that is capable of measuring pressures ranging between 0.3 to 4.5 psi. It employs a Wheatstone bridge circuit which is used to detect and measure the pressure differential between two points. It is used in various application fields such as in hydraulic systems, air systems and vacuum systems.
