Application

Bidirectional, compact, radio module for automatic meter reading (fixed network or Walk by/Drive by) that can interface with:

• Sensus radio endpoints like iPERL
• Repeater – Repeater
• Repeater – Sensus Sirt
• Repeater – Sensus Gateway

Designed to collect meter data in periodical interval or communicate on demand to a fixed radio transceiver or gateway. Critical events like alarms are lead automatically through the radio network in less than 20 minutes when immediate alarms are supported by the radio endpoints.

Repeaters work as a relay station for the received radio transponder modules and forward the data over longer distances to the handheld or gateway. The overall performance depends also depends on all components and available software.

The maximum number of repeaters in a chain can be up to 7 hops; the maximum number of radio endpoints per repeater is 100. The Sensus Radio Repeater uses an integral lithium battery and doesn’t need external supply voltage. It can transmit over a longer distance because of its higher output power.

The distance to the first repeater is set by the meter endpoint or the reading device and is line of sight 500m, under normal conditions outside a building 100m to 200m, hard conditions e.g. pit installation 20 m to 100 m.

Repeater to Repeater or Repeater to Gateway is min. 1000m line of sight.

The output power depends on the frequency according the regulations for the available frequencies.

There are two versions of frequencies: Standard 868 MHz, optional 433 MHz (all components should be the same frequency).
