Some gas monitoring requirements are basic but important. The
RKI M-Series transmitter is a highly reliable and very cost-effective
4-20 mA transmitter for the detection of carbon monoxide and
hydrogen sulfide. This transmitter operates from a 24 VDC (11
VDC to 30 VDC) power source and provides a 4–20 mA output
signal, which can be connected to a wide variety of RKI or third
party controllers. The M-Series transmitters are built for use in
either indoor or semienclosed areas.
The electronics are protected inside a plastic enclosure to avoid
damage from mechanical abuse, water, dust or corrosion. Sensors
for the M-Series have a long life-span that typically last two to
three years.
Field calibrations are very basic and can be completed by a single
person. The zero and calibration functions for the MSeries are
performed by simply adjusting potentiometers on the amplifier
board. The amplifier board is equipped with easily accessible test
jacks for the connection of a voltmeter. The voltmeter is used to
view sensor response while the calibration gas is being applied
and the potentiometers are adjusted with a screwdriver.
