Q&A

What sensors are compatible with the X3 data logger?

The X3 data logger is compatible with sensors that support a native SDI-12, RS-485, or RS-232 output. The X3 also supports tipping bucket rain gauges. Analog sensors (0-5 VDC, 4-20mA, etc.) can be integrated using an analog-to-digital adapter (mV-RS485-UW).

How are sensors connected to the X3 data logger?

The X3 data logger utilizes waterproof UW plug/receptacle connectors. The logger ports are female receptacle, so all sensor cables will need to terminate with a male plug connector. If sensor cables aren't already terminated with this connector, customers can send in their sensor cable for a UW plug connectorization service (UW-CON). Alternatively field-wireable plug connectors (UW-FWP) and flying lead cables (UW-FLx) are available for customers to wire/splice at their facility.

What power options are available for the X3 data logger?

A variety of power options are available from NexSens depending on the application. When AC power is available, a UW6-PW powers the X3 data logger directly from an outlet, while the UW6-BB offers power through a trickle-charged SLA battery so that the system is not interrupted during a power outage. For remote deployments, both 15-watt (SP15) and 32-watt (SP32) solar power packs are available. The solar power packs feature an integrated battery and regulator behind the panel for autonomous power/charging. When integrated on NexSens data buoys, the X3 data logger is powered from the buoy's internal battery and solar charging. Customers also have the option to purchase a UW 6-pin plug to flying lead cable (UW6-FLx) to tie in with supplied or existing 12VDC battery sources.

Can the X3 data logger be integrated on a data buoy?

Yes, the X3 is IP68 waterproof rated and designed to be integrated on the CB-Series and XB-Series data buoys. This gives customers the flexibility to switch the same data logger hardware between pole-mount and buoy-based deployments as needs evolve.
