SD-1DRI-CH4 SD-1DRI Detector Head, methane (CH4) 0 - 100% LEL, 4-20 mA transmitter with sample adapter (flow through chamber) 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
  • Self-diagnosis by microprocessor
  • Low power operation (Maximum: 3W)
  • Explosion proof: ATEX, IECEx, ExdIICT5

Applications

  • LNG Terminal
  • Petrochemical/Chemical plants
  • Power plant
  • Utilities
  • Iron and steel works

*Please note we can only ship RKI products to customers within the United States
