High performance sensor released

Switzerland-based IR Microsystems, a leader in compact, tunable laser diode based gas sensors for monitoring, safety and process control, has revealed its innovative new sub-ppm ammonia gas detector, targeted toward applications in industrial safety, refrigeration, emission control, life-stock farming and agriculture.

The “microLGD” gas sensors are offered as stand-alone systems or OEM sub-mounts for the continuous monitoring of NH3 and other gases like O2, CO2, CH4, and H2O. Compared to current gas sensor technologies, IR Microsystems’ next generation gas detection products feature exceptional advantages such as extremely high selectivity, calibration-free operation, low-cost-of-ownership, and functional safety.

“The ammonia sensor performance combined with its long lifetime is unmatched in this class of instruments and especially out-plays traditional electrochemical cell sensors,” said IR Microsystems’ CTO, Dr Bert Willing.

The patented measurement principle is based on Tunable Diode Laser Spectrometry (TDLS) and results in unique products without a reference channel, allowing for simpler, lower-cost systems. The sensor comprises a microprocessor-driven read-out module with digital and analog data outputs for industry-standard connectivity (I2C-bus, RS485, RS232, or 4-20 mA) and is built ready-to-use for rapid OEM integration into stand-alone units, detector networks or explosion-proof housings.
