C7393 is an equipment used for air pressure measurement. It is an electronic pressure transducer typically used for precision, medium and low pressure, which can be used in scientific laboratories, HVAC, industrial process control and other applications. It features ultralow power consumption, low cost, high accuracy, and is capable of providing reliable measurements in difficult environmental conditions.

The C7393 is designed to provide an accurate representation of air pressure within the range of 0 to 1000 kPa. To deliver this level of accuracy, the transducer consists of a ceramic diaphragm, a protective shield, a Wheatstone bridge circuit, and a pressure sensing element. The pressure sensing element is sealed within the ceramic diaphragm and is made up of the sensing beam, the reference beam, and two resistors.

The C7393 uses the piezoresistive effect to measure the air pressure. When the pressure is applied to the ceramic diaphragm, it expands and contracts, which causes a strain on the beam and the resistors. This strain causes a variation in the resistance of both the sensing and reference beams which alters the bridge balance of the circuit. This variation is then converted from an analog to a digital signal using the bridge-balanced amplifier circuit. The digital signal is then fed to a frequency-to-voltage converter, which generates an output voltage proportional to the air pressure. As this output voltage increases, the pressure being measured also increases.

The C7393 has several applications where it can be used to measure air pressure. It can be used in HVAC systems to measure pressures and fan speed, and in industrial process control applications to measure air flow and velocity. It can also be used in scientific laboratories to measure static and dynamic pressures. It is also commonly used in pneumatic systems, such as air cylinders and valves, to measure the pressure of the air being used. The C7393 is also used in medical devices and clinical instruments, such as intravenous infusion pumps, where it is necessary to monitor air pressure to ensure accurate delivery of drugs.

The C7393 provides an accurate and reliable method for measuring air pressure. It has a wide range of applications, from HVAC to medical devices and scientific laboratories. The transducer is designed to be sturdy and reliable in difficult environmental conditions, and is capable of providing accurate measurements in all conditions. Its low cost and low power consumption make it an attractive solution for a variety of applications.
