Anticollision Telemeters

• Intervention distances adjustable:
  • from 4 m to 20 m (RDM/20);
  • from 5 m to 30 m (RDM/30);
  • from 5 m to 60 m (RDM/60);
  • from 5 m to 99 m (RDM/99)
• Digital setting of distance in metres. Measurement resolution: 1 metre, with indication independent of environmental and ageing-related factors.
• Digital indication of the distance in metres via luminous display in cabin.
• Acoustic signalling of slowing and stopping (optional, via Mod. RDM-RC repeater).
• Directivity superior to any other system currently on the market (-3 dB at 3°).
• Minimal power density of emitted signal: 3,5µW/cm2 in contact with the parabola.
• No danger to people or objects (limit of Osha=1 mW/cm2).
• Easy alignment of the reflector with the transmitter, guided by LED indicators located both on the display unit and on the parabola.
• Unaffected by normal bridge-crane skew.
• Unaffected by variations in power supply voltage of +15/-20% at constant rate.
• Unaffected by sudden variations in power supply voltage due to spikes up to - 40%.
• Measurement unaffected by rising hot air currents, vibrations, humidity, rain or dust.
• Autodiagnosis of transmitter group, receiver, frequency modulator, quartz time base and power supply; any failure is signalled by dropout of the stop relay.
• No preventive maintenance.
• All operations controlled by a microcomputer.
• Anti-interference filter between conductors and earth for voltages up to 3 kV for 500 µs or 1500 V 50 Hz for 3 s.
• Electronics unit in IP55 container.
• Operating voltage: 110 V 50/60 Hz; 220 V 50/60 Hz on request.
• Operating temperature: -15 ÷ +70°C.
• Absorbed power: 25 VA.
• Relay current-carrying capacity: 10 A 250 Vca.
• Complies with CE and international regulations regarding electrical safety and electromagnetic compatibility (EMC).
• Unrestricted-use transceiver equipment (ERC/REC 70-03E).
