Abstract
A transducer in the form of a potentiometer provides an output signal indicative of a position of a component. The potentiometer comprises a body, a member moveable relative to the body and having an end portion for coupling to the component, and a resistor mounted to the body. A wiper is coupled to the member and forms a slidable electrical contact to the resistor. The potentiometer also comprises a contactor means for providing selectable contact positions to the resistor of respective first and second electrical conductors, so as to provide a selected operating section of said resistor.
Claims18
A potentiometer for providing an output signal indicative of a position of a component, the potentiometer comprising:
- a body;
- a member moveable relative to the body and having an end portion for coupling to said component;
- a resistor mounted to the body;
- a wiper coupled to the member and forming a slidable electrical contact to the resistor;
- and
- contactor means for providing selectable contact positions to said resistor of respective first and second electrical conductors, so as to provide a selected operating section of said resistor.
The potentiometer of 1, wherein the potentiometer is provided with two contactor plates, one for connection of each of the first and second electrical conductors to the resistor.
A rotary transducer for providing an output signal indicative of an angular position of a component, the transducer comprising:
- a body;
- and
- a shaft having an axis, the shaft being rotatable about the axis relative to the body and having an end portion for insertion into an aperture of said component,
- wherein the end portion has a plurality of segments, the segments being splayed apart from the axis so as to provide a resilient gripping action when inserted into the aperture.
A rotary transducer for providing an output signal indicative of an angular position of a component, the transducer comprising:
- a body;
- and
- a shaft having an axis, the shaft being rotatable about the axis relative to the body,
- wherein the body comprises an axially centred circular flange for mounting of the transducer by threaded fastening means, the flange having arcuate slots for receiving the fastening means, so as to allow adjustment of the angular position of the transducer,
- and wherein mounting inserts are provided surrounding each arcuate slot, the inserts having a face for abutting a head of a fastener, and being of a material which resists permanent deformation when the fastener is tightened.
A rotary transducer for providing an output signal indicative of an angular position of a component, the transducer comprising:
- a moulded plastics body;
- and
- a shaft having an axis, the shaft being rotatable about the axis relative to the body,
- wherein the transducer has electrical connections for providing a supply voltage to the transducer and for providing the output signal from the transducer to an instrument panel or controller, the electrical connections being provided by way of a multi-core cable permanently moulded into the moulded plastics body.
