The CGS-FlexVu UD10 combustible-gas detection system combines a catalytic-bead gas sensor with a multifunction universal display for detection of a wide range of hydrocarbon gases, as well as hydrogen, in harsh industrial environments. The explosion-proof system is third-party rated for safety integrity level (SIL) 2, and is suitable for high-temperature (up to 75°C) and hydrogen-processing applications, as well as in relative humidities up to 95%. The universal display also provides output and control capabilities, and can be used to calibrate and view information. The device features nonintrusive calibration using a handheld magnetic tool or a HART communicator and can be easily calibrated by one person. The display unit provides a linear isolated/non-isolated 4–20-mA output signal (with HART). — Det-Tronics, Minneapolis, Minn.
