Temp. indicator with switch not affecting display - contains two bourdon springs acting in mechanical isolation

A temp. indicator with a switch contains a Bourdon spring connected via a capillary to a measurement sensor. The switch is operated via a lever depending on the actual value driving the spring and an adjustable demand value. The effects of the switching mechanism on the temp. actual value display ar...

More Information
Summary:A temp. indicator with a switch contains a Bourdon spring connected via a capillary to a measurement sensor. The switch is operated via a lever depending on the actual value driving the spring and an adjustable demand value. The effects of the switching mechanism on the temp. actual value display are substantially excluded over the entire range of indication. The indication remains within calibration within normal tolerance limits. The lever arrangement (25) is actuated by a second Bourdon spring (2) moving in mechanical isolation from the first (1) and connected to the sensor via the capillary (17,18). Each Bourdon spring acts on an axial hollow shaft (12,15). Both hollow shafts are arranged on a common shaft (16) so as to be mutually independently rotatable.
