<p>A double temperature unit permits regulation of two different parameters while retaining ability to measure actual values of each or the difference with respect to reference settings. A double regulator is mounted in a box (Z) which has a front panel assembly (1) in which are mounted two crown wheels (8, 10) which engage with pinions (12, 13) on shaft (14, 15). These shafts are rotated by knobs (20, 21) which engage with slots (14b, 15b) in the shaft ends. The crown wheels carry contacts (25, 26) for engagement with resistive windings (27, 28) which determine the preset reference values for the regulator. These are indicated on dials (9, 11) and the values are compared by electronic circuits mounted in the box. The pointer (30) of a galvanometer (29) indicates difference values.</p> |
