    SD-1GH-ACN SD-1GH Detector Head, 0-100 ppm ACN (acrylonitrile), 4-20 mA Transmitter by RKI Instruments

    RKI Instrument's model SD-1 Series smart combustible gas, toxic gas, oxygen, and organic vapor detector/transmitter is a robust and reliable explosion proof design for detecting LEL and ppm levels of hazardous atmospheres. In addition to measuring the common %LEL levels of methane, hexane and isobutane, for example, the SD-1 Series also has the capability of measuring a wide variety of toxic organic compounds in a PPM range such as acrylonitrile, ethylene oxide, n-methyl pyrolidone, methylene chloride and many others. This gives the SD-1 Series a unique niche in RKI's gas detector line-up. The SD-1 has an ATEX/IECEX approval for the explosion class ExdIICT5 and has an IP-65/67 ingress protection rating.

    The SD-1 has a 4-20mA signal output as well as relay contacts for interfacing with other control systems or monitoring facilities. All SD-1 types are also available with HART communication instead of 4-20mA relay. SIL2 is available for the IR, EC and OX types. In facilitating non-intrusive conditions in hazardous atmospheres, the SD-1 can be calibrated and it's menus navigated with magnetic switches and a magnetic key.

    Features

    • Wide range of detectable gases: % LEL Combustibles, catalytic; % LEL Combustibles, IR; H2S, CO, & O2; PPM for acrylonitrile, hydrogen, ethylene oxide, n-methyl pyrolidone, methylene chloride, and many others
    • Sensor types include: Catalytic, Galvanic Cell, MOS, IR, & Electrochemical
    • Direct digital display of gas readings
    • HART Communication protocol or 4-20 linear output
    • Available with SIL2 approval (IR, EC, OX versions)
    • Easy maintenance using a magnetic key
