LSVW5 – 5CH VW Wireless Datalogger

LONG RANGE
LOW POWER CONSUMPTION
QUICK SETUP USING ANDROID APP
EASY INTEGRATION TO LSGWAY NETWORK

The LSVW5 is a 5 channel  wireless, low power and user-friendly data logger for all pluck-type vibrating wire sensors on the market.

 

Description

The LSVW5 is a low power and long range wireless Vibrating Wire (VW) data logger designed to monitor all pluck-type vibrating wire sensors on the market.  The LSVW5 can be used to monitor up to 5 vibrating wire instruments.

The LSW5 is ideal for use in small and medium size projects, and especially for piezometers, strain gauge and other vibrating wire applications.   

Its non-volatile memory can store up to 5×72,500 records. Each record includes the VW reading and temperature reading with time and date. When the memory is full, recording either stops or overwrites the oldest record.

Data can easily be retrieved in Hz and Engineering Units from any network connected computer thanks to the web based software through the LSGWAY.  Data can also be retrieved locally using a USB cable. Data is collected in CSV format and further facilitates download to a spreadsheet software for post-processing.

The LSVW5 is housed in an IP 67 enclosure fitted with cable glands for signal cable.

The LSVW5 requires 4 lithium C-Cell battery providing power for up to up to 10 years in a moderate temperature and readings taken every hour.
