Pressure sensors and transducers play an important role in monitoring industrial applications such as processes, production lines, and critical machinery. The 85-300G-0R is a differential pressure transducer designed for measuring and monitoring pressure changes in liquids, gases, and steam. It can be used in a wide range of applications from detecting and measuring leaks, to monitoring air conditioner refrigerants, to measuring vacuum in process systems.

Description

The 85-300G-0R is a low cost, miniature, dual-input differential pressure transducer that offers an optional on-board temperature compensation feature. It has a direct drive structure that provides a high degree of accuracy and stability. The transducer is constructed of a lightweight, precision engineered plastic casing that can resist the corrosive elements of some processing applications such as strong acids and alkalis. The output is a linear 4-20 mA signal, and the transducer is typically powered by a 12volt DC supply.

Application Field

The 85-300G-0R is designed to be used in a wide variety of industrial processes including process control, fluid flow, leak detection, air pressure sensing, and level monitoring. It has a high level of accuracy and is suitable for use in systems that require a low level of vertical lift. The transducer is typically used in applications such as gas and liquid pressure monitoring, pumps, compressors, ventilation systems, and level monitoring.

Working Principle

The 85-300G-0R utilizes a dual-input differential pressure transducer to measure and convert changes in pressure into a linear 4-20 mA signal. At the heart of the transducer is a diaphragm that is constructed to flex freely when pressure is applied to it. On one side of the diaphragm is the reference pressure, while on the other side is the applied pressure. This difference in pressure is then converted into an electronic signal which is output to a controller or other monitoring device.

The transducer is designed to maintain a high degree of accuracy by using a large diaphragm and a direct-connect drive structure. The diaphragm is constructed from a resilient material such as stainless steel or plastic and has a small amount of deflection when pressure is applied. The direct-connect drive structure then converts the diaphragm’s deflection into a linear electrical signal which is sent to a monitoring device.

The 85-300G-0R is also equipped with a temperature compensation feature that allows for high accuracy readings over a wide range of temperatures. This feature also offers protection against condensation and corrosion as the transducer is resistant to many hazardous and caustic chemicals. It is also designed to operate in a wide range of temperatures from -40°C to +125°C.

Conclusion

The 85-300G-0R is a low cost, miniature, dual-input differential pressure transducer that offers an optional on-board temperature compensation feature. It has a direct drive structure that provides a high degree of accuracy and stability. The transducer is suitable for a variety of industrial applications such as process control, fluid flow, leak detection, air pressure sensing, and level monitoring. It is also designed to operate in a wide range of temperatures from -40°C to +125°C. The 85-300G-0R is an excellent choice for accurate and reliable pressure sensing and monitoring in industrial applications.
