The LTE Telemetrylogger 255EB is a compact data logger that can be independently powered by batteries despite very frequent remote data transmission. In the conventional measuring site setup, a Datalogger was often supplied via solar-cells or a fixed mains connection. At many stations it won’t be necessary anymore by using the more cost effective with less maintenance Telemetrylogger. Up to 9000 web-based data transmissions can be done with only one set of batteries. This means hourly remote data transmission with a minute measurement interval over a period of one year. The LTE Telemetrylogger 255EB is very often used in measuring points for surface water in order to realize a continuous and frequent transmission of measured values, also for the equipping of redundant stations.
In the case of extreme events, the ingenious alarm management also offers the possibility of event-controlled transmissions of measured data even more frequently so that you can access the latest measured values even in tense situations.
Of course, the LTE Telemetrylogger 255EB can also be used in regular groundwater wells. With hourly measurement and daily data transmission, the device has a battery life of at least 10 years.
With HT devices, you neither have to check the humidity in the device nor regularly replace desiccant cartridges. Useless work and operating costs that can be saved. Thanks to a proven filter system that has been used in different climate zones for over 20 years, reliable relative pressure measurement for measuring the water level is guaranteed.
The data transmission in the standard version takes place via the cellular network directly to a FTP server. For security reasons, the transmission can also be done by using SSL encryption. If the battery is low or in case of an alarm if limit values are exceeded, alarm messages can be sent.
