Description
Product overview
The LGS31-001 is a potentiometric data logger with a single measurement channel for resistance sensors. It supports real-time monitoring and local recording, and buffers measurements when radio communication is lost.
Modes
Main features
Transfer functions
Transfer function is linear for Rp = 1 kΩ to 10 kΩ and complex for Rp = 10 kΩ to 650 kΩ. These functions are integrated in RF Monitor and can be exported to other reception tools.

The LGS31-001 is a potentiometric data logger with a single measurement channel for resistance sensors. It supports real-time monitoring and local recording, and buffers measurements when radio communication is lost.
Modes
- Monitoring mode: measurements are transmitted in real time to a receiver. If transmission fails (key not plugged, PC off, RF Monitor not running, communication issue, etc.), the logger stores data in buffer memory and forwards them automatically when communication is restored.
- Record mode: measurements are stored in the logger memory and downloaded by radio on user command via RF Monitor; intended for campaigns without instant transmission.
Main features
- Potentiometric interface, 1 channel
- Measuring range: 1 kΩ – 650 kΩ per channel
- IP65 aluminium enclosure; supplied ½-wave antenna; SMA connector
- Power supply: AA Lithium Thionyl battery (included) with plug-in connector
- RF range: 100 m – 1 km (depending on receiver antenna)
- Memory: 32,256 timestamped measurements
- Measurement frequency configurable from 1 s to 4 h
