The ENCO-METER rotary/linear converters are electro-mechanical devices designed to transform the linear movement of the end of a cable into a proportional electrical signal. The device consists of a micro-cable made from stainless steel wrapped around a drum of precise diameter to obtain an accurate winding of 200 or 250 mm per revolution A spring sets a constant torque on the drum which rewinds the cable and ensures that it always maintains the same tension. A roller guide system ensures that the cable is correctly rewound. The mechanics described ensure that the angular movement of the drum's axis is in direct proportion to the movement of the cable. The rotation of the drum's axis is transmitted via a coupling to the electronic device which receives the signal. This can be an accurate potentiometer (analog output) , an incremental encoder or single absolute encoder and parallel or serial multiturn (digital output).
The converters in the ENCO-METER range are produced in duraluminium and stainless steel. The do not require any lubrication or maintenance.
