Pressure transducers form a critical function in today's closed loop systems providing data for safety, control and alarm functions encountered in typical industrial applications such as heating boilers, HVAC/R, compressors, test stands, fire suppression equipment and power generation. Pressure sensors measure a wide range of benign and corrosive media, with temperatures ranging from -70 to 300°F.
System integrators and panel builders traditionally relied on pressure sensors mounted to bulkhead fittings to interface between the sensor, panel and process. In a typical application, the pressure sensor is mounted inside the panel, installed into a bulkhead fitting and sealed by means of Teflon tape or face O-ring. The seal between the sensor and bulkhead fitting is critical and if not formed correctly, it can lead to leaks and eventual failure of the system particularly systems that handle water, steam, corrosive gases and liquids.
The AST4200 panel mount pressure sensors were specifically designed to overcome this problem by providing hermetic seal against the media. The solid one piece 17-4PH or 316L high strength stainless steel design is free of welds, internal O-rings or fluid filled cavities, making it ideal for applications that require high proof and burst pressures. The sensor requires minimal mounting configuration and uses a locknut to hold the sensor to the panel. Two wrench flats on the nose of the sensor allow the user to tighten the external pressure tubing to the sensor without turning the part. Common pressure port configurations include 1/8" NPT female and 1/4" NPT male. Other AST product lines can be offered with the special Panel mount fitting with the use of Option Code "066." For these instances, contact AST to ensure the configuration is available.
