![]() ![]() V-Logger is housed in an IP68 enclosure with cable glands for signal cable. One lithium D-cell battery provides power for 9 years for the 4-channel logger (over 6 years for the 8-channel logger) in moderate temperatures, assuming readings taken every hour Choice of thermistor or RTD for temperature channels Sensor ID, serial number, calibration factors, and sweep range for each sensor. ![]() Minimum interval is 15 seconds for the 4-channel logger and 30 seconds for the 8-channel logger Reading intervals can be specified by day, hour, minute, and second. Logger start time can be set to a specific date and time so that readings are synchronized with other loggers. Memory mode determines if logging stops when memory is full or if logging continues by overwriting earliest readings When memory is full, recording either stops or continues by overwriting previous readings, starting with the oldest, depending on how the user set up the logger during installationĭate, time, memory mode, and communication settings. Each record includes a VW reading and temperature reading with time and date. Stores 65,520 records per channel in secure, nonvolatile memory. Reads thermistors or RTDs in the range of -20 to 120☌ Reads vibrating wire sensors operating in the range of 450-6000 Hz. The Extra Cap Battery option adds 3 additional lithium batteries for at least 10 years of battery life (9 years with 8 channels) with readings every 15 minutes in moderate temperatures or approximately 9 years battery life (5 years with 8 channels) in extreme cold weatherĢ30 x 200 x 95 mm (9.1 x 7.9 x 3.7 inches) Hermes Wing (Base Station) North America (902 - 928 MHz) VW V-Logger Specifications V-LOGGER MODELSĤ-Channel V-Logger with Radio, North America (902 - 928 MHz)Ĥ-Channel V-Logger with Radio, Europe (863 - 870 MHz)Ĥ-Channel V-Logger with Radio, Australia (915 - 928 MHz)Ĩ-Channel V-Logger with Radio, North America (902 - 928 MHz)Ĩ-Channel V-Logger with Radio, Europe (863 - 870 MHz)Ĩ-Channel V-Logger with Radio, Australia (915 - 928 MHz) ![]()
