Pressure Sensors, Transducers

Pressure sensors, transducers come in a wide variety of types and configurations that measure an extensive range of applications. HSCMAND150PA4A3 strain gauge pressure transducer is a transducer which combines a miniature pressure transducer and a stainless steel sensing diaphragm with high accuracy and excellent overpressure capabilities. It has industrial-grade applications in a wide variety of industrial, automotive, and commercial applications such as HVAC, pumps and compressors, chemical/petrochemical plants, medical equipment, energy management systems, instrumentation systems, and food processing/meat processing equipment.

Application Field

The HSCMAND150PA4A3 pressure transducer is designed for industrial applications. It is ideal for applications requiring high-accuracy readings in a wide range of temperatures. The pressure transducer is designed to detect pressure range from 15 to 150psi, with an accuracy of +- 0.2%, and a better than 0.1% repeatability.

The pressure transducer is capable of of operations at temperatures from -40°F to 120°F (-40°C to 50°C). It is capable of detecting and monitoring pressure in hazardous areas, and applications that require high vibration resistance. It is designed to be low-level, vibration-resistant, and can work with non-corrosive process gases.

The HSCMAND150PA4A3 transducer is suitable for a variety of industrial applications such as HVAC, pumps and compressors, chemical/petrochemical plants, medical equipment, energy management systems, instrumentation systems, and food processing/meat processing equipment.

Working Principle

The pressure transducer works on the principle of pressure strain gauges (PSG), which consist of strain gauge elements which are coated on to a stainless steel sensing diaphragm. This diaphragm expands or contracts when subjected to pressure. The expansion or contraction of the diaphragm causes a corresponding strain in the strain gauges which in turn results in a change in resistance. This change in resistance is converted into a linearized pressure signal by means of a Wheatstone bridge circuit, which is output to the user.

The HSCMAND150PA4A3 PSG transducer is connected to a 4-20mA current signal converter. This converter converts the analogue signal from the PSG transducer to a 4-20mA current signal that can be read by a compatible device. This 4-20mA signal is used to detect and monitor changes in pressure over its range. The transducer is also equipped with an integrated electronics module with temperature compensation, which enable it to accurately monitor pressure in a wide range of temperatures.

Conclusion

The HSCMAND150PA4A3 pressure transducer is an ideal pressure sensing device for industrial applications requiring high accuracy readings in a wide range of temperatures. It is capable of detecting and monitoring pressure in hazardous area, non-corrosive process gases and can be used in a variety of industrial applications such as HVAC, pumps and compressors, chemical/petrochemical plants, medical equipment, energy management systems, instrumentation systems, and food processing/meat processing equipment.The pressure transducer works on the principle of pressure strain gauges and is connected to a 4-20mA current converter for detecting and monitoring pressure changes over its range.
