Neodym Launches ProtiSen™ Sensors
April 19, 2007 (via Canada NewsWire ) - Mr. Juraj Krajci reports:

Vancouver, BC - April 19, 2007 - Neodym Technologies Inc. is pleased to announce the availability of ProtiSen™, a hydrogen sensor intended for gas safety monitoring in hydrogen powered vehicles and in power generation equipment such as fuel cells and battery charging systems.

ProtiSen™ monitors perform linear sensing of hydrogen in air from 0 to 40,000 ppm (4% volume in air) with 200 ppm resolution and fast start-up/response time. The environmental operating range is -40 to +80 degrees Celsius and 0 to 99% R.H. The devices can be powered from 5 to 24VDC and consume about 750mW. Output signal options include 0-3VDC proportional, voltage-encoded state (normal, warning, alarm, fault), TTL, and open drain (2A at 60V). The devices are compatible with Neodym's PK-Port™ single-wire digital signaling protocol for PC-based real time monitoring and data logging.

ProtiSen™ monitors employ catalytic sensing elements with in-line VOC filters and feature good long-term stability, increased tolerance of silicone-based contaminants, and immunity from sensor damage in the event of hydrogen overexposure from massive gas leaks or during aggressive testing.

ProtiSen™ monitors are housed in anodized aluminum enclosures, measure 51mm by 51mm by 19mm, and weigh about 50g. The devices are manufactured in Canada by Neodym and cost approximately USD150.
