Description
Application and performed functions: TRANSOLVER has been designed for operation in analog and digital automatic control and measuring systems working in harsh environmental conditions. Its basic application is interaction with the positioning actuators of automatic control systems, where it works as a feedback signal measuring transducer. Compact design and general-purpose software make possible using TRANSOLERS in many other metrological applications such as robotics, weather measurements, radar systems, air-conditioning and remote control systems. Especially TRANSOLVER has been designed for assembly in actuators manufactured by ZAP S.A. in Ostrow Wielkopolski and CHEMAR SA in Kielce and those other ones that have been adapted for building in typical potentiometers.
Design: The transducer consists of an enclosure with a screwed stem for mounting, rotary axle provided with 2 ball bearings, waterproof membrane type keypad with two pushbuttons and a LED display that is resistant to low and high temperature, rear cover with a watch glass and undetachable screened cable 500 mm long. Inside, there is a resolver (contactless angular position converter) and a microprocessor type processing system. Different length of the cable and axle are available when ordered.
Sealing: The axle - fluorovulcanizate, back cover - water-proof diaphragm, electronic components - silicone filling compound cured chemically.
Mounting: The transducer should be mounted to a base plate, 1.5÷3 mm thick, in a hole F 10 mm dia., using a locknut and a crown washer (provided in the set). A gear coupling to be mounted on the axle. As there is no mechanical limiter, the gear wheel may be rigidly mounted on the axle. The cable should be cut to a proper size, the ends mended and fitted with terminals and the heat-shrinkable tubing provided in the set. The larger tubing and terminal are for the screen end. Should the gear eccentricity be found (in older actuators) a flexible type base plate to be applied or adequate tooth clearance to be allowed for.
Functioning: TRANSOLVER is a two-conductor angular position transducer. The measuring element is a resolver. The measuring signal from the resolver is numerically scaled to 4÷20 mA current in a measuring line, in proportion to the axle deviation from a defined reference starting point. TRANSOLVER has an intelligent algorithm of selecting the starting and end point of the measuring range. Both parameters are controlled independently. The transducer has not been provided with any mechanical angle limiter. The measuring range can be defined from 0°÷ 70° (minimum), and up to 0°÷360° (round angle maximum), with the optional setting of the initial position, and the sense of rotation. Overrunning the measuring range results in such transducer response as it is read unreliable by the automatic control system, with additional specifying the side from which the range has been overrun.
