Pressure Sensors, Transducers

Pressure sensors, usually known as transducers, measure the pressure of gases, liquids or both. The pressure sensors measure the force applied to the surface area and then produces an electric signal as a result of this measurement. Pressure transducers play an important role in many industrial applications, such as measuring hydrostatic head, flow, pressure, level, atmospheric pressure and environmental and atmospheric conditions. Therefore, pressure transducers have numerous applications in industrial fields.

DLVR-L10D-E2NS-C-NI3F pressure transducers are digital sensors designed to measure liquid and gas pressure in response to the pressure of a medium. It can measure pressures up to 1,500 psi, and has high accuracy, repeatability, and stability. This pressure transducer is equipped with a 24 bit ADC, which can convert pressure values into digital signals. A variety of output modes, including 0-5 V analogue output, 0-10 V analogue output, RS485 serial port output, Modbus-RTU electronic pressure transmitter, and PWM signal output, can all be used to transmit pressure information in various ways.

The Working Principle

The working principle of DLVR-L10D-E2NS-C-NI3F pressure transducer is to use the processing and controlling chip, A/D converter, linearity, temperature compensation circuit, and its sensitive component. The silicon micro-acts as the sensitive component, which integrated pressure sensor chip is connected to a Wheatstone bridge circuit. The displacement of the diaphragm, due to the pressure difference inside and outside the pressure chanbe, is converted to the electrical resistance, completing the loop of bridge.

The change of electrical resistance caused by the pressure difference will cause the imbalance of the bridge. The differential voltage of output is directly proportional to the pressure difference, which is converted into a digital signal through A/D conversion chip, representing the voltage corresponding to the current pressure. And then this data signal is transmitted to the control system for process and display.

Application Field

The DLVR-L10D-E2NS-C-NI3F pressure transducers are mainly used in industrial production automation fields, such as hydraulic printing presses, heat exchangers, pumps, water heaters, chemical pumps, air filter systems, pipe filtrations, and various types of industrial machinery.These pressure transducers are also have been widely used in a variety of commercial applications, such as medical instruments, industrial robots, beverage and food producing equipments, sensor in combustion chambers, and aircraft fuel systems.

Conclusion

The DLVR-L10D-E2NS-C-NI3F pressure transducers are a reliable and cost-effective pressure measuring device. By using a sensitive components, A/D converter, linearity, temperature compensation circuit and processing and controlling chip, it is able to measure a wide pressure range and accurately convert into digital signals. As a result, DLVR-L10D-E2NS-C-NI3F pressure transducers have found various application field in industrial and commercial productions, such as printing presses, beverage equipments, medical instruments, and aircraft fuel systems.
