Abstract:
An arrangement and a method are provided for determining the position of an elevator car in the elevator hoistway. The arrangement includes a measuring apparatus fitted in connection with the elevator car. The measuring apparatus is arranged to form an electromagnetic radio-frequency measuring signal, for determining the position of the elevator car. The arrangement also includes a position identifier fitted in a selected location in relation to the elevator hoistway. The position identifier is arranged to connect inductively to the electromagnetic radio-frequency measuring signal, and also after it has connected to send a determined pulse pattern using the electromagnetic radio-frequency measuring signal.
