Description

In magnetic compasses, it has long been known to use liquid resistance sensors to transmit compass readings to a distance.

The most important demands

The systems for remote control systems presented are as follows:

1. Automatic transfer of instrument readings — within the limits of the full azimuth scale, without any additional operations for performing each reference.

2. The absence of the need for an individual for each device or a special uneven scale of the indicator (i.e., complete uniformity of the scale).

The great majority of sensors with fluid resistance do not meet the first requirement. These are not compasses, but semi-open passes indicating the e magnetic course iB within the entire azimuth scale, but only the direction of deviation from the course given by a special handle on the transmitter.

 It is influenced by the fact that, with the simplest OIHI co-struc- tures, the P1011 of the indications is predicted from a full circular scale, while the pointer scale is almost completely uniform.
