ABSTRACT:
A differential pressure indicator and method of configuring a differential pressure indicator is provided. The differential pressure indicator is configurable to provide open circuit or closed circuit logic and includes a housing, a pressure responsive element, a post, first, second and third electrical contacts and an electrical insulator from an insulative material. The electrical insulator separates the third electrical contact from either the first contact or the second contact to provide a desired type of logic. The differential pressure indicator may use substantially similar components to provide either open circuit or closed circuit logic or the components may be rearranged to provide either open circuit or closed circuit logic.
