Data Sheet A-Series Miniature Watertight Pressure Switches SELECTION GUIDE Before selecting a switch the following should be considered: Actuator:    The actuator responds to changes in pressure and operates the micro switch element in response to these changes. The actuator is normally exposed to the process media and must be chemically compatible with it. There are three types of actuators available for the A-Series switches – all welded 316 SS diaphragm sealed piston; 316 SS piston with Viton™ O-ring seal; and 316 SS piston with Buna-N O-ring seal. The 316 SS diaphragm is available in ranges...

Data Sheet A-Series Miniature Watertight Pressure Switches ADDITIONAL SWITCH TERMINOLOGY Accuracy – (See repeatability) Accuracy normally refers to conformity of an indicated value to an accepted standard value. There is no indication in switch products; thus, instead, the term repeatability is used as the key performance measure. Automatic Reset Switch – Switch which returns to normal state when actuating variable Pressure is reduced. Adjustable or Operating Range – That part of the nominal range over which the switch setpoint may be adjusted. Normally about 10% to 100% of the nominal range...
