Plexus IWS - Distributed Control Systems Oxygen/Pressure/Temperature
Plexus Controls Intelligent Wireless System (IWS) nodes comprise of a range of distributed wireless products from Plexus Controls providing advanced supervisory, control and data acquisition (SCADA) functionality for commercial and industrial applications. With 'out the box' auto mesh wireless functionality and low power requirements, the IWS Methane and Oxygen Gas Analysis System (GAS) can be easily installed at a flare or well site and connected into the biogas pipe using ¼” sampling and return tubes providing a flow through using a pitot tube or orifice plate.
The IWS-R-O2PT takes a reading 24 times a day (programmable). Methane content (% volume), system static pressure and gas temperature is taken and reported via MODBUS TCP or Plexus database portal at the gateway. The system gateway provides functionality including alarm email/sms notification and GUI map display via a webpage. The gateway system stores all readings with date/time stamp. All data may be downloaded a regular basis (programmable) or continuously monitored in real time over a WAN connection such as a cell modem.
Plexus IWS GAS system uses the latest digital IR (methane sensor), and digital fluorescence quenching (oxygen sensor) technology with 1 year calibration validity. Either sensor can be swapped out in the field in a few minutes and recalibrated for another year.
IWS-R-O2PT systems are powered through an internal 24V DC power connection or 12V solar system (optional, must be specified at the time of ordering). A 24V 1.5A power adapter is provided with the system (non-solar version)
