Elevator positioning system - USP

As an alternative to the classic magnetic sensors for the reading of the cabin position in the shaft, there are several alternative solutions on the market.

For this application the USP system by SCHMERSAL based on driving ultrasounds along a metallic wire hanging in the shaft is extremely valid and reliable.

A transmitter attached to the cabin runs along the metallic wire and directs ultrasound signals to a receiver positioned in the headroom or in the pit.

The receiver is therefore able to survey the absolute cabin position in the shaft and to send it directly to the PLC of which our control panels are equipped.

Connecting our MITSUBISHI keyboard to the PLC you can set deceleration and stopping quotes in order to considerably speed up the installations.
