MODEL SD-1 SERIES
Explosion Proof Transmitter
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.
