WERMA Signaltechnik

WERMA Signaltechnik logo
WERMA Signaltechnik is one of the world’s leading companies in the design and manufacture of optical and audible signal devices commonly known as beacons and sounders.  Their signal devices ensure that the working environment is safe and processes efficient – whether on machines or within process systems, in the factory, in the office, or in public spaces. From signal towers, beacons and warning lights to sounders, buzzers and horns, WERMA optical and audible and explosion proof signal devices warn and protect people throughout the world.

WERMA Modular Signal Towers

Modular Signal Towers

WERMA signal towers offer endless combinations of optical and accoustic accessories through the modular design of the product. A simple bayonet mechanism incorporating electrical connection enables the user to assemble a tower quickly and simply.

Modular signal towers provide an important visual signal of, for example, status change on a machine, equipment or in a process. In emergency situations they then provide a clear optical and accoustic warning of danger.

WERMA Pre-assembled one piece signal towers

Pre-assembled one piece signal towers

Pre-assembled one piece signal towers may be selected and order with just one part number. Using LEDs they offer life of typically up to 50,000 hours.

Modular signal towers provide an important visual signal of, for example; status change on a machine, equipment or in a process.

WERMA is introducing a new elegant signal tower range to the market. Signaling Technology in its most spectacular form ClearSIGN combines a slim unobtrusive design with cutting edge technology and functionality.   The homogenous light effect is particularly impressive and when a light is activated comes to life in a unique form. ClearSIGN uses purely LEDs which help create an unobtrusive minimalistic design with a high level of functionality.

Clearsign is available in two versions; Clearsign compact and Clearsign modular. Clearsign compact is a pre-assembled 3 or 4 tier signal tower. Clearsign modular on the other hand employs the proven bayonet locking system which permits the selection of up to six different elements for the tower underlining the well-known flexibility of WERMA design.

An IO Link version is available which enable the device to be used for the first time as a level or temperature indicator. The signal tower fills up with light and changes color when a critical level or condition is reached. All functions are simple to program using the IO Link interface.

RGB LEDs allow a wide variety of colors to be selected for any tier of the tower giving the operator maximum flexibility in choice of light effect and color. The optical signal can be enhanced with an optional audible alarm.
