FDMET400
Methane gas detector
Methane gas detector complete with base with relay output. FDMET400 detectors signal the presence of methane gas in concentrations below the lower explosive limit (LEL), meaning well before an explosive mixture forms. The detector has an alarm relay output with changeover contact (NO and NC), a fault output with opto-isolated NC contact, and two terminals for connecting a current-absorbing line for conventional control panels.
