The 195-WS-16 Data Logger is designed specifically for collecting meteorological data. It has a versatile processor that can be used in systems from portable stations to networks. It is a complete package with sensor interfaces, data processing and logging, communications interfaces, and software for display, reporting, and data retrieval via a standard RS232 cable. Two independent user programmable alarms are supplied.
The 195-WS-16 supports a large variety of sensors. A 30-pin terminal strip is supplied for directly connecting analog and digital sensors without the need for external signal conditioning components or special programming. Sensor data are sampled every 2 seconds and logged at intervals selected by the user. The averaging period and logging interval can also be changed by the user. Each data record is logged with time and date. Data memory is backed with a 7 year lithium battery. Wind data are calculated in vector and scalar forms. The internal microprocessor determines weather parameters, generates standard reports, handles communications, and performs self-diagnostic tests.
The 195-WS-16 is typically powered by 12 Vdc. Operating current is less than 55 mA at 12 Vdc. An optional low power version is available for remote battery operated stations.
The 195-WS-16 is a completely self-contained data collector and processor for automatic stations. It is designed to withstand exposure to severe outdoor weather conditions. All components are contained in the rugged NEMA-4X weatherproof fiberglass enclosure. Internal circuit boards have surface mounted components for improved reliability. Three stages of lightning and transient protection are included on all signal and power connections. A desktop version is available for indoor use.
Data can be viewed using Windows HyperTerminal or other terminal programs such as Procomm. A one page real-time text display or an ASCII row and column format may be selected. A menu is provided for setting the date and time, alarms, logging interval, etc. Optional graphical display software is available for viewing real-time and historical data charts and graphs.
