"Electronic two-point controller for" temperatures with a setpoint " setting potentiometer and on it attached ring scale "«

Leaf 1

Electronic two-point controllers, preferably for controlling temperatures, are "known", namely in the execution that the setpoint adjustment potentiometer is arranged in a vertical position behind the 3? front plate of the instrument. The axis of the setpoint adjustment potentiometer penetrates here 'the Iront plate and is. on the outward-facing end an adjustment

button arranged. This arrangement has the part that the setpoint adjustment potentiometer takes up a very large tree behind the front of the instrument5 d. must do the front of the instrument very large, especially if _s should be placed on the Frontfläohe additional signal lamps, auxiliary scales, eg ■ zur.Einstellung of repatriation and trip distances. . ■

A further embodiment is known in which the _s Reference Setting potentiometer is arranged in a horizontal position, but 'has this potentiometer on the lateral surface knurling that the Irontplatte partially throughput. This device has the disadvantage that dust and moisture can penetrate the instrument unhindered. In addition, the arrangement of a knurl right next to the scale has the disadvantage that the. This makes the scale dirty and illegible over time. Another disadvantage is that the scale is covered with your finger during adjustment and is thus invisible.

The invention is based on the object eliminate multiple disadvantages of the known instruments. ■

The solution to the problem is that the setpoint adjustment potentiometer in a horizontal position 'Position arranged within the housing is and is operated via a Winke! or the like, whose axis is the front surface penetrates and on de.sse. outwardly towards Axle end a linstellknopf od. The like. Arranged is.

How the innovation can be carried out in detail emerges from the following description and the drawings, in which an exemplary embodiment is shown schematically, namely by their own. ■

Fig. 1 is a perspective view of the subject of the invention,

Fig. 2 is a partial cross-section through this one

Behind the Iront frame 1, the cutout in the front frame "is covered, a glass plate 2 is arranged and closely behind it, the scale plate 3 * is arranged on the front frame , which carries the potentiometer upper part 6, on which the potentiometer lower part J is mounted. At right angles to the potentiometer 6, J , an egg wheel 9 or the like is under the potentiometer * · lower part 7 on the surface 8 . Arranged, which is attached to a> * -, axis 10, which is mounted in the chassis 5.! This axis 10 penetrates the scale plate 3 and the glass plate 2 dust- and splash- • waterproof and is.außen on the end of the axis de In order to prevent unauthorized adjustment, another adjustment device can also be arranged instead of the adjustment knob 11. The adjustment scale 12 is applied to the ring-shaped side surface of the potentiometer and is represented by a NEN cutout in the scale plate 3 and through the glass plate 2 is visible from the outside.

This horizontal arrangement of the whole potentiometer creates a lot of free space under your

- 4th

Adjustment knob obtained from the outside and inside under the potentiometer itself, making Signal lamps, auxiliary scales, eg # for setting of feedbacks and switching point distances., -. appropriate - can be arranged.

Furthermore, the housing 4 is on its inner surfaces equipped with catches-13, which-, when-. ' with the instrument pushed into the side cut-outs "14 grab, which are mounted in Halterungen.15 and these brackets 15 are fixed to the Chassis 5 connected or with this one piece.

The inflation is not limited to the details shown, but also modified executable if only. the features of the invention come to expression.
