The product is not intended for use in potentially explosive areas. The product is designed for fitting to a GEMÜ valve in order to detect the position of linear actuators visually and electrically. The product has a microprocessor controlled intelligent position sensor as well as an analogue travel sensor system (poten- tiometer) which is positively connected with the actuator spindle by means of a mounting kit (spring, operating bush). -
