The Sensidyne special range Acetylene sensors (0-50% LEL, 1.25% by volume) for cylinder charging operations address user requirements for maximum sensitivity and reliable leak detection from below 10% LEL to 25% and 50% LEL alarm levels with excellent accuracy and response time. Acetone, used as a liquid solvent to prevent explosions, does not interfere with the Sensidyne sensor measurement of Acetylene LEL. The SensAlert ASI is approved by Factory Mutual (FM) for Class I, Division 1, Group A, hazardous (classified) areas and has SIL-2 certification for both hardware and software.
Air operated aspirators are commonly used to draw a sample from appropriate locations near the charging manifold stations or scales. The intrinsically safe SensAlert ASI sensor head enables remote installation without expensive rigid conduit to position sensors near Acetylene generators, purifiers and driers, or other leak-prone areas while installing the transmitter at an easily accessible location.
Expected 5-year sensor life and 6 month maintenance interval combines with SensAlert ASI reliability to achieve the lowest cost solution for cylinder filing operations. Low power requirements allow the system to be used in Mobile Acetylene Trailer Systems when they are enclosed to such an extent that there is no natural ventilation.
SensAlert ASI is the best solution for Acetylene cylinder charging facility compliance with NFPA 51A. Contact Sensidyne for assistance engineering the appropriate gas and flame monitoring system for your plant or facility.
NFPA News Update
Amendments to NFPA 51A require Acetylene cylinder charging plants to upgrade to listed and approved Acetylene gas detection and “fast acting” optical flame detection. Installed instruments should provide the highest reliability, lowest failure, and easy maintenance.
Sensidyne has an approved gas and flame detection solution for Acetylene cylinder charging plant compliance with the NFPA 51A 2012 amendments.
