The Horn is an optional item that can be used with Super-Beacons, Super-Beacons-Outdoor, Industrial Super-Beacons, Industrial-RX, Mini-RX or Mini-RX-Outdoor to extend the range of a precise distance measurement or 1D tracking to up to 100m in a single submap. With multiple submaps, it is possible to cover very large objects – tunnels, bridges and similar – up to several km (radio range defined) with beacons installed every 80-100m that leads to a significant economy as compared to a typical recommended distance of up to 30m between Super-Beacons without Horns.
The Horn is designed for:
The Horn consists of a plastic horn with an embedded external microphone. The microphone is connected to receiving beacon via a flexible 1.6mm cable. The cable may have easy to connect to a Super-Beacon 4×4 connector (no soldering required) or open wires (soldering requires and works with Industrial beacons and Mini-RXs).
Typical configurations for the distance measurements or 1D tracking:
Many other combinations of RX and TX beacons are possible.
Recommended ultrasonic frequencies for the TX beacon is 25kHz or 19kHz. Range is decreasing with higher frequency. External noise is increasing with lower frequency. Optimal is 19kHz for largest range or 25kHz and more, when you have noisy environment.
Different types of Horns can be produced on request. The default variant: 100-170mm length and 20 degrees beam.
This is an RX horn. Separately, you can order a TX horn as well that would increase the distance even further (up to 150m) or it would make the distance measurement even more confident in noisier conditions.
