In process control systems it is often necessary to query and analyse sensor or status data over large distances. Classic data transmission via cables, however, involves considerable costs since the route is often too long and/or inaccessible. The Laird Controls wireless data systems obviate the need for expensive cable installations and the associated maintenance costs.
Wireless data systems are of particular advantage where industrial plants are not tied to a specific location, e.g. in open cast mining. Due to the continually changing topography of the terrain, data transmission by cable can seldom be implemented economically.
These systems also offer an effective solution in vehicles, e.g. in locomotives in shunting yards where status data is transmitted for speed control purposes from the signal box to the driver.
