SentryGSM3DLogger application

SentryGSM3DLogger is an advanced, low cost solution for data logging with the key feature being the email output capability. This device is used mainly for meter reading, with data exported daily or weekly to a web server.

DIN Rail mounting, this industrial quad band GSM device can monitor and data log up to 12 inputs, send alarms via SMS, plus export data logged information by email or to a web based application server for storage and display. Sentry Telemetry’s Windows-based software provides remote configuration of all variables, message recipients' etc.

The SentryGSM3DLogger offers a cost-effective data acquisition solution to OEMs, instrumentation, sensor and meter companies, MCC manufacturers, industry and factories. Through our in-house application engineering and web hosting services, we can develop custom telemetry and data management solutions.
