A temperature sensor for use with HOBO U-Series external-channel data loggers, this model measures temperature in air, water, or soil. Accuracy and resolution vary according with attached logger model. Measurement range is -40° to 50°C (-40° to 122°F) in water or soil, -40° to 100°C (-40° to 212°F) in air; response time is minutes typical to 90% in air moving 1 m/sec (2.2 mph); response time in stirred water is 1 minute typical to 90%.
The Logger is a modular, reconfigurable data logging system used in energy and idustrial monitoring applications. The 15-channel sustem enables the user to quickly and easily perform a broad range of monitoring applications. You can use the HOBO FlexSmart Logger with a number of Smart Sensors. It can also be sued with FlexSmart signal conditioning modules to covert signals from many types of Onset and third party sensors. HOBOware software communicates with the logger, allowing you to customize the configuration settings, download data from the Logger, and plot the data for analysis.
The Pulse Input Adapters are used to log the number of switch closures per interval and are designed to work with the HOBO Weather Station and Micro Station data loggers. The adapter has a plug-in modular connectore that allows it to be added easily to the Weather Station or Micro Station. Two versions are available for easy interfacing with either mechanical contact closures or solid-state electronic switches. The contact closure version is ideal for connecting to tipping bucket rain gauges.
The H600 is a current-sensitive switching device which monitors current (amperage) in the conductor passing through it. A change in amperage in the monitored conductor which crosses the switch threshold will cause the resistance of the status output to change state, similar to the action of a mechanical switch. In this model, the threshold is fixed at 150mA AC max (200mA AC for 50Hz operation). The status output is suitable for connection to building controllers, or other appropriate data acquisition equipment operating at up to 30 volts. The H600 requires no external power supply to generate its output.
