Setra’s model 550 low-pressure transducer features a 3:1 range turndown for field adjustment from 110% to 32% of the nominal range, making this unit well-suited for applications that are subject to overpressure. Adjustment is made via the switch and potentiometer conveniently located on the top of the transducer housing. The Model 550 is packaged in a rugged 316 stainless steel housing for use in general-purpose and submersible applications. A male or female threaded pressure fitting is offered for general-purpose applications, and an open-face style with a KF25 flange is offered for submersible applications. The Model 550 circuit is RFI/lightning protected, virtually eliminating costly field replacement.

Principle of Operation

The capacitive sensor is constructed of an electrically isolated stainless steel electrode and ceramic diaphragm, mounted closely and in parallel to each other. The diaphragm is capable of slight flexing under applied pressure. A minute change in applied pressure alters the gap between the electrode and the diaphragm. This change is detected by a custom-designed ASIC, amplified, and converted to a high-level linear output signal that is proportional to applied pressure.
