Analog electronic position switches [t-head1-first]

Two types are available:

Analog, mechanically actuated position switches directly linked with the world of automation

Analog position switches LSE-AI (4 to 20 mA) and LSE-AU (0 to 10 V) represent another innovation in electronic position switches. Using them, it is now possible for the first time to monitor the actual position of a flue gas valve or an actuator continuously. The actual position is converted in analog fashion into voltage (0 to 10 V) or current (4 to 20 mA) and then continuously signalled to the electronics. Even objects of varying sizes or thicknesses, such as brake shoes, can be scanned and the results processed further.

Simple rotational-speed dependent control systems of fan motors or smoke-venting blowers signal the opening angle of the air damper (e.g. 25, 50 or 75 %) and thus save power and material wear. The analog position switches also have a diagnosis output for further processing of data. This means that the safe status can be monitored and analysed at all times. The position switch also has a self-test function. The outputs Q1 and Q2 are constantly scanned for overload, short circuit against 0 V and short circuit against +U_e.
