RFC52 Recording Temperature

This instrument is a recorder with a mechanism that has single switch control capability which provides automatic temperature programming by use of a pre-cut plastic cam. An internally-mounted three-wire thermostatic relay insures extremely long switch life and often eliminates the need for an external conductor. Wall mounted (brackets furnished) or flush mounted. CSA listed.

Overview / Design Principle:
This instrument is a recorder with a mechanism that has single switch control capability which provides automatic temperature programming by use of a pre-cut plastic cam. An internally-mounted three-wire thermostatic relay insures extremely long switch life and often eliminates the need for an external conductor. Wall mounted (brackets furnished) or flush mounted. CSA listed.
Operation:
Control point of the RFC52 is determined by a cam-follower which rides the edge of a revolving pre-cut cam and postiions the snap-acting switch in accordance with the program for which the cam is shaped. Cam is configured and fabricated by end user.

The switch is actuated by the same temperature responsive mechanism which moves the recording pen, actuated when the pen point is at the center line of the cam follower, the switch operates the three-wire thermostatic relay which handles the load.
