Industrial Scientific is pleased to announce the release of a complete stand-alone fixed system consisting of an audible and visual alarm mounted directly to the iTrans™ and wired to the low and high alarm relays. Different audible tones distinguish between low and high alarms while the ultra-bright strobe and LED display alert workers that a gas hazard is present. An optional 24 VDC power supply can be added to create a complete plug-in functional system that is easy to install and operate.
A 4-20 mA output and ModBus interface, allow the unit to be connected directly to a PLC, DCS, or standalone control system. Industrial Scientific’s “smart” sensor technology allows for single or dual sensor operation. The sensors can be mounted directly onto the iTrans™, or placed remotely up to 200 meters away. The unit can be upgraded in the field by adding a second sensor at a later date. This capability makes the unit extremely flexible and cost-effective.
