Seven Channel Wireless Node

LORD MicroStrain Sensing Systems have introduced a new 16-bit resolution A/D version of their popular wireless multi-channel node.

The V-Link-LXRS Wireless 7-Channel Analogue Input Sensor Node features 4 differential input channels with optional Wheatstone bridge completion, 3 single ended 0-3 volt input channels, and an internal temperature sensor channel.

The new 16-bit V-Link allows a typical accuracy of 0.1% of full scale, and supports a wide range of user-supplied Wheatstone bridge and analogue sensors including strain gauges, load cells, torque, pressure, acceleration, vibration, displacement, geophones and more, and enables measurement and monitoring in remote applications.

The node can simultaneously log data to the internal memory or transmit real-time data to a host computer at user programmable data rates. Node Commander software supports configuration of the wireless node including discovery, initialisation, radio frequency, sample rate, reading/writing to node EEPROM, calibrating node sensors, managing node power including sleep, wake, and cycle power, and upgrading node firmware.

The node comes packaged in a 74 x 79 x 20mm (plus antenna) ABS housing, which also houses a 3.7V rechargeable lithium ion battery. External power can also be supplied if required. The V-Link is compatible with any of LORD MicroStrain’s WSDA- Base or WSDA-1000 base stations, and applications would include rotating component monitoring, health monitoring of aircraft, structures and vehicles, and experimental test and measurement.
