.~ With control means responsive to sensed condition
DEFINITION
Classification: 96/102
With control means responsive to sensed condition:
(under subclass 101) Apparatus in which means are provided to detect an apparatus or process characteristic or a change therein and to control or regulate operation of the apparatus or process based upon the detected characteristic or change therein.
(1) Note. In this subclass a single means may be used both to detect the characteristic or a change therein and to implement an action in the apparatus based upon the detected characteristic or change therein. There must be a positive action made by the means because of the detected characteristic or change therein. An example is a pressure relief valve in which a certain pressure must be reached before the valve opens to relieve pressure differential across the valve. Another example is a thermostat with a bimetallic element in which a certain temperature must be reached before the element is deformed enough to trip a
switch, thus implementing a control action in the apparatus as a result of the temperature or change therein. Apparatus in which no positive action is made by the single means as a result of the detected characteristic or change therein is not classified in this subclass, but is classified below.
