Description

The VL-BR Strain Gauge Bridge Data Logger is a single channel, battery powered, stand-alone strain gauge bridge data logger. It supports one 4/6 wire Wheatstone bridge by providing voltage excitation, excitation voltage compensation, and low-level signal amplification. Data is stored in nonvolatile flash memory for later retrieval.

The VL-BR Strain Gauge Bridge Data Logger features a measurement input voltage range of -8 mV to +8 mV to accommodate most common bridges with a sensitivity of up to 3 mV/V.

Featuring an aluminum enclosure and PCB coating, the logger has excellent performance in the harshest industrial environment.

Powered by 16-bit ADC and programmable input range, the logger is well suited to science and laboratory applications where precise and accurate measurement is critical.

Siteview software is required and sold separately. One license per site, can be used on multiple loggers.
