Overview / Design Principle:
This instrument is a recorder with a two switch control mechanism which provides automatic temperature programming by use of a pre-cut plastic cam. It is used when two temperatures separated by not more than 5% of scale range are specified as control points. The instrument contains two internally-mounted three-wire thermostatic relays. Wall mounted (brackets furnished) or flush mounts. CSA listed.
Operation:
Control point of the RFC15-52 is determined by a cam-follower which rides the edge of a revolving pre-cut cam and postiions the snap-acting switches in accordance with the program for which the cam is shaped. Cam is configured and fabricated by end user.
Switches are actuated by the same termperature-responsive mechanism which moves the recording pen, operating at preselected points in relation to the center line of the cam follower roller.
First switch to be actuated on a temperature rise is the leaf-type #15 if normal sensitivity. Second is a super-sensitive #52 pin type, actuated only when the recorded temperature exceeds the operating point of the first switch.
