Ceiling mounted remote sensor heads monitored the lighter than air Hydrogen while the SensAlarm Plus enclosure was installed outside the entry door. Locations to consider include: Performance criteria for an area hydrogen leak detection system should be established for the specific application intended. Hydrogen leaking from a system should be detectable by one or more of the human senses (sight, smell, hearing, taste, and touch). The sensitivity of the detector to other gases and vapors should be considered in the selection of the detector and should be explained to personnel. However, it is recommended that the sensor have a range of 0 to 10 vol% with a lower detection limit of 0.1vol%. Hydrogen leak testing is the normal way in which a hydrogen pressure vessel or installation is checked for leaks or flaws.This usually involves charging hydrogen as a tracer gas into the device undergoing testing, with any leaking gas detected by hydrogen sensors. The GD402 senses the % Hydrogen while providing feedback on which mode it is in (Hydrogen in Air, Hydrogen in Carbon Dioxide or Air in Carbon Dioxide). Grainger's got your back. When in contact with concentrated hydrogen gas, the tape quickly changes from light gray to dark black in the event of a leak due to vibration or seal failure. Arrgh Manufacturing in Novato California produces an American-made hydrogen gas detector and forced ventilation fan system for use in battery charging rooms and other areas where hydrogen may be present. On price (and we know you are interested in this first) we come in at the lowest of all the systems that we looked at. Use of helium is recommended, if available, as its atomic size is similar to hydrogen and will help identify small leaks. Use inert gas and bubble indicators (soap in water) to identify leaks during system/vessel checkout. Hydrogen Gas Detection Equipment Hydrogen (H 2 ) is a colorless, odorless, and tasteless gas that is highly flammable and explosive, especially at high temperatures. The Hydrogen leak detection system utilizes a simple plug-and-play interface connection to the Sentrac Hydrogen gas sensing device. The GD402's information is relayed back to the DX Advanced via analog and discrete inputs where it is converted into trends and digital indications. In common practice, one or more Hydrogen sensors are ceiling mounted and either turn-on or modulate a ventilation fan. Connection Line with Quick Connect Fittings .
