OTT Hydrometry has launched a new range of dataloggers; the ‘OTT netDL’ (internet datalogger) series, which have been designed to improve remote monitoring by making communications easier, more reliable and less expensive.
UK Managing Director Simon Wills says "This has been achieved through compatibility with almost any communication method and by building in data path redundancy, so that netDL loggers are able to guarantee high data availability, and by incorporating web connectivity we have dramatically reduced the cost of data transfer whilst also making data collection extremely simple and convenient."
In order to minimise the cost of monitoring systems, the netDL loggers are modular, so that users can specify their own requirements with regard to the number of inputs and outputs and communication methodology. Again flexibility is key; with I/O options for analogue, pulse, SDI-12, RS232 and RS485 the loggers are able to take data from a wide range of sensors. Communication options include a built in GSM/GPRS modem, internet access and if required, satellite, radio or landline modem connectivity are available for additional communications redundancy protection.
In addition to the latest communication technologies, netDL loggers also provide enormous onsite data collection capacity. An on-board memory that stores up to 0.5 million readings, together with options to log different sensors at different speeds, to automatically change logging speeds at pre-set (alarm) conditions and to ‘dial out’ on alarm, the loggers are able to record the data of greatest value.
As a specialist manufacturer of field-use monitoring equipment, the OTT engineers are keenly focused on the development of instrumentation that is able to operate with extremely low power consumption and the battery powered netDL range is no exception, with options for wind or solar panels to ensure long-term unattended operation.
Each logger has a USB interface, a backlight display and a user operated jog shuttle, so it is also possible to view all data, reconfigure the logger or to collect data whilst on site – without a laptop if necessary.
