and Data Logger GSM-2
Battery powered, low-maintenance, robust
GSM-2 is a combination of an autonomous data logger and a remote data transmission unit in one device. When linked to a pressure transmitter or water level sensor, GSM-2 can autonomously collect up-to-date measurement values for pressure and temperature (and optionally for conductivity as well) and then transmit this data via SMS, e-mail or FTP using the GSM wireless network (GPRS connection).
The GSM-2 remote data transmission unit is normally used in hydrology and hydrogeology applications as a means of recording water levels. It is also used by construction companies for pressure measurements. The remote data transmission unit is offered in various housings that accommodate different installation requirements in the locations where it is to be used. With its wide range of water level sensors and pressure transmitters, KELLER is able to offer the right solution for virtually any measuring situation.
The transmitted measurement data is received via the free GSM Datamanager software system, which also processes, stores and displays the readings. The transmitted data is received via the free GSM Datamanager software system which also processes, stores and displays the readings, and allows for remote configuration from the user’s workstation.
GSM-2 stands out through the following attributes:
• High-level of data security (internal, non-volatile memory)
• Low maintenance (battery operated, service life of up to 10 years)
• Robust and able to withstand short periods of immersion
• Adaptable (available in various housings)
• Can be used in various applications (many different sensor interfaces available)
• Free data management software (Datamanager)
• Integrated barometer and temperature sensor
GSM-2 is available in the following housing variants:
||For installation inside tubes ≥ 2" with one pressure transmitter or level sensor
||For installation outside tubes with up to 5 pressure transmitters or level sensors
||For installation outside tubes with one pressure transmitter or level sensor
||For field measurements with up to 2 pressure transmitters or level sensors
||For pressure measurements in potentially explosive gas and dust atmospheres
