System principles of operation
2.1
Appropriate applications
The Eltek GenII wireless telemetry system is ideal for a wide variety of
applications that involve the accurate monitoring of data in conditions where
events are slow moving.
Therefore, the system works well in applications such as measuring the
environment in a building or following a process. However, the system cannot
accurately record values that change very quickly. (<500mS)
2.2
Transmitter interval
The GenII system is a one way telemetry system. There is no need for a
receiving or polling device at the transmitter unit, meaning battery endurance
can be several years using off the shelf batteries.
Transmitters send the sensor value(s) or averaged (transmitter dependant)
sensor values at a random point in time within the configurable
transmitter
interval
.
The receiver is continuously active. The random transmissions from the various
transmitters are held in a
pending value register
that is successively updated
as newer, valid transmissions are received.
