Wind speed sensor with sound and light alarms.

Designed in accordance with ITC MIE-AEM-2, from the elevation and maintenance apparatus regulations regarding tower cranes in construction works and other applications.

  • Measuring range up to 180 km/h
  • Beacon with sound and light alarm included
  • Stainless steel bearings
  • Power supply: from 48 to 400Vac


Operation

The device performs under the ITC MIE-AEM-2 guidelines. Intermittent pre-alarm activation at 50km/h and continuous alarm activation at 70km/h.

The unit includes the possibility of reducing the alarm trigger values to increase safety.

The pre-alarm intermittently activates the yellow beacon light and the siren. It is activated when the wind speed is between the chosen values, normally 50 km/h – 70 km/h.

The continuous alarm activates the red beacon light and the siren when the wind speed exceeds the maximum value (normally 70km/h). The alarm latching can be configured so that it can only be deactivated by cutting off the power supply.

SAG-105WR is supplied with a 3x1.5 1000 V cable according to Low Voltage Regulations. IED’s design and production process are in accordance with ISO 9001.


Power Supply

  • SAG-105WR is supplied with a 3x1.5 1000 V cable according to Low Voltage Regulations. IED’s design and production process are in accordance with ISO 9001.
  • Range power supply: from 48 to 400Vac.


Anemometric Sensor

The device is a single and compact set that consists of a wind sensor, the electronics and a sound and light beacon. It requires minimal installation.


Fixation - Clamps and magnets supplied

Zinc plated steel clamps that can be fixed to irregular parts measuring up to 63 x 45 mm.

Fixation magnets for flat ferromagnetic surfaces.

The magnet fixation system can support up to 90 kg.


Other Options

Wind tunnel calibration certificate

An individualized certificate for each device is provided.

Pulses output

The device can be supplied with a pulses output to be connected to a display or a PLC (please, see our WM44 range displays).

Integration with remote control

Suitable to view wind speed on the remote control.

Relay output

To drive other mechanisms or alarm signals. Crane power supply automatic cut-off when the alarm is triggered is not recommended since it might lead to overstress in the crane structure.
