This analyzer utilizes a long-life electrochemical ' fuel cell' sensor for the detection of oxygen in process gases. The sensor produces a small millivoltage output which is directly proportional to the oxygen detected. The output is then amplified and displayed on a digital readout meter and can also be sent to an optional recorder output. The 410 can be supplied with sampling pump or pressure regulator to suit most applications. MODELS There are seven types of mounting configurations available : ⢠410N4 - Wall mounted NEMA4 ( IP65) enclosure rating ⢠410N4X - Wall mounted corrosion-resistant NEMA4X ( IP65) enclosure rating ⢠410N12 - Wall mounted NEMA12 ( IP52) enclosure rating ⢠410PM - Panel mounted, slides open for easy access ⢠410RM - 19" ( 483mm) rack mounted, on sliding rails ⢠410N7MC: Wall mounted NEMA7 UL/ CSA explosion-proof with non-intrusive magnetic calibration, Class 1 Div 1 Group BCD ⢠410PMN7: Wall mounted NEMA7 sensor housing with panel mounted control cabinet ( two separate enclosures) SPECIFICATIONS Method of Detection : Customer replaceable electrochemical ' fuel cell' O2 sensor.
