FIELD: measuring instrumentation.SUBSTANCE: actuator includes: case frame (2), measuring converter (3) containing optical sensor (41), spring element (6) capable of expansion or contraction in Y direction, actuator elements (5, 15) capable of contraction against resilience of spring element (6) when power is supplied, and guide element (17) for linear movement of measuring converter (3) in direction X. When power is supplied to the actuator (5), measuring converter (3) moves in line inside the case frame (2) to measurement position; when power is supplied to actuator (15), measuring converter (3) retracts in line from measurement position into the case frame (2) into idle position.EFFECT: improved reliability.8 cl, 28 dwg |
