Stalker 3G VW Logger​

The Stalker 3G VW Logger is a variant of the mA datalogger. It is compact, low power & easy to deploy. It reads vibrating wire (VW) & temperature sensors & transmits results wirelessly over the Internet to the WASP web portal for storage, processing and display. The same web portal is used to configure the logger.

The Stalker 3G VW Logger comprises digital WASP (WASP-D) and VWstalker. Each VWstalker can read 2 VW and 2 temperature sensors. Each WASP-D can power and control up to 2 VWstalkers. The WASP-D communicates with the VWstalker using the SDI-12 protocol.

Before installation, the VWstalker is programmed and pre-wired to the WASP-D. Once on site, VW sensors are connected to the VWstalker. The user then logs on to the web portal to set up logging and reporting schedule.

The WASP-VW is ideal for new and retro-fit instrumentation projects where unattended collection of readings from VW sensors is required.
