WIRELESS REMOTE FOR VIRTUAL DATALOGGING
The Canary Systems WRMT-VW-24S is a Wireless Remote Station designed to monitor vibrating wire sensors. The Remote Station does not contain a data logger and does not require pairing with a Base Station; instead, it can be connected via a wireless network directly to a PC that is running MultiLogger™ software and serves as virtual datalogger. The WRMT-VW-24S contains a Canary Systems VW Comm Module, Canary Systems MicroMux or MiniMux multiplexer, and Lantronix WBX2100E Wibox Radio.
The VW Comm is a vibrating-wire interface designed to automatically monitor a variety of instruments, including vibrating wire, flowmeters, linear potentiometers and 4-20mA, among others. The excitation and measurement parameters are programmable to support all commonly used vibrating wire instruments. The VW Comm Module also supports reading YSI44005 type thermistors to provide sensor temperature measurements, and supports other thermistors or temperature devices as well.
In addition to the vibrating wire and thermistor input capability, a single-ended voltage up to 2.5 VDC can be measured. A high accuracy 2.5 VDC reference is also provided for powering other sensors such as RTD’s and linear potentiometers. The VW Comm can also read the power supply voltage and internal temperature. The VW Comm provides 1 sensor input. The optional MicroMux or MiniMux multiplexers provide 4 and 16 additional channels of VW sensor inputs, expanding the channel measurement capability to 4 or 16 sensors, respectively.
The Lantronix WBX2100E WiBox Radio provides connectivity to a deployed wireless 802.11b/g network and comes with a 2.4GHz 9 dBi Yagi Antenna.
Power to all components is supplied by a rechargeable 12V 24AHr lead-acid battery including a 30W solar panel. The battery is suitable for several weeks of operation without sunlight, and is delivered installed and ready to use. It should last for about 3-5 years. The application and measurement interval have a large effect on battery life.
At the bottom of the custom steel enclosure are connections for the solar panel, external antenna and 2 or 4 cable glands for vibrating wire sensors. The charging is controlled by a Sunsaver charge controller unit. There are LED indications on the Sunsaver and WiBox Radio.
Warranty for the WRMT-VW-24S is applicable for 1 year.
