Transmitters vs Receivers
What They Do?
Elsema systems allow signal transmission between distant devices without physical connections. This gives complete flexibility in controlling systems from one point to another. Both are commonly used together in two-way radios, automation lines and machinery control where constant, accurate signals are required. A wireless data transmitter and receiver combo keeps commands and feedback flowing instantly.
They also play a key role in traffic control, environmental monitoring and multi-device coordination. In industries where signal precision is vital, Elsema’s products deliver reliable, swift data exchange, helping to maintain smooth operations and system safety even in demanding conditions.
How They Do It?
Elsema uses digital signal encoding to ensure data integrity and prevent overlap between channels. Each transmitter uses unique codes so that messages reach only pre-set receivers. This avoids interference or incorrect commands from other units. Operating on 433 MHz provides an ideal range-to-power balance.
The transmitters convert data into RF pulses, while the receivers decode the pulses into clear digital instructions. This encoding process also includes security layers that protect against frequency scanning and unauthorised access. Elsema’s internal circuit designs improve error-checking, maintaining precision even when mild interference is present, ensuring critical operations always receive exact instructions.
