UW-FWP Wiring
The UW-FWP and UW-FWP-V terminals provide a means of interfacing a flying lead sensor cable to a NexSens UW-8 SensorBUS connector such as the sensor ports on X2 and G2-series data loggers. The ‘-V’ variation is vented and should be used with vented pressure transducers. Cable wiring and installation instructions can be found here.
