Air Compressor, 809 Series Pressure Sensor



Rather than running extra electrical wires around a job site, compressed air is a very common source of low-pressure energy used in industrial applications.  Compressed air is used on construction sites to run large power tools like cement chisels and jack hammers.  It is also used widely on factory floors to handle or move parts.  For example, a manufacturing facility may use compressed air to close a fixture around a part to perform a manufacturing step.  Or, a commercial bakery might use a burst of compressed air to blow a poorly baked roll off a conveyor belt. 



Challenge:  Finding a pressure sensor that can provide a high number of cycles as well as be airtight to prevent leaks. 

When working with compressed air, leaking is a large waste of this energy, up to a 30% loss.  Having a tightly sealed sensor will reduce this waste.  Also, many manufacturing routines are extremely repetitive and can cause a high number of cycles to be placed on the equipment.  Devices on the system (including pressure sensors) need to be able to be accurate over a very long lifetime.    


Solution:  809 Series Pressure Sensor

809 Series Sensor

The 809 Series Pressure Sensor use no internal O-rings in the chamber that holds air.  The stainless-steel pressure ports and sensing diaphragms are laser-welded together to make an air-tight seal.  This will prevent leaks today as well as years in the future as O-rings can break down over time and cause leaks.  Along with the 100 million cycle lifetime, the 809 series Pressure Sensor are a perfect fit to provide a continuous feedback of air pressure to your controller.
