Frequency Output -an output in the form of frequency which varies as a function of the applied pressure. Full Overtravel Force -the force required to depress the plunger of a switch to the full overtravel point. Gage Pressure -a form of differential pressure measurement in which atmospheric pressure is used as a reference. Typically used in sensing magnetic fields. Hardwired -physically interconnected and intended for a specific purpose.
Hardwired logic is essentially unalterable.
Hazardous Location -defined as an area in which flammable or combustible mixtures are present. High Contamination -heavy particle laden air, extreme washdown environments, grain elevators. Hermetically Sealed Switch -a switch completely sealed to provide constant operating characteristics. Hysteresis, Switching -the principle associated with sensors, such that the operate point is not at the same level as the release point. In solid state sensors, it is accomplished electrically.
