Ammonia Gas Detector FLD 4000
Laser based leak detector for confined space installations
No False Alarms
Photonic Innovations Ltd (PIL) laser sensors are programmed to lock onto a unique absorption feature of the target gas, in this case ammonia. This renders an extremely high detection fidelity. This technology allows it to avoid the false alarms common in chemical sensors that occur due to cross gas reactivity and sensor depletion.
Virtually No Maintenance Required
PIL’s laser sensors are not depleted upon exposure to ammonia and other toxic gases. This means that frequent maintenance/calibration is no longer a requirement. With no filaments or chemical components, there is no need to calibrate the device and no need to replace sensors.
Ultra Reliable Sensors
PIL’s laser sensors monitor ammonia concentration in the engine rooms at all times without degrading due to prior exposure. This means response time is consistently high. When tested against a market leading ammonia detector (fixed module) as seen in figure 1 below, PIL’s FLD 4000 (blue curve) responded an order of magnitude faster than the market leading ammonia detector (green curve); an important aspect when a massive gas leak or an explosion could be seconds away.
