|4-20 IQ INTELLIGENTTRANSMITTER
model 4-20 IQ is a microprocessor based intelligent sensor
transmitter. It comes equipped with a digital display which
provides a local reading of the gas concentration. Operating
on 14-24 VDC power, it provides a linear 4-20 mA output proportional
to the gas concentration, and is housed in an explosion-proof
casing. The 4-20 IQ has been UL Classified and CSA Approved
Class I, Div. 1, Groups B, C, and D. The 4-20 IQ can operate
as a stand-alone instrument, or it can be used with an IST
control unit to provide control room readings and alarm relays.
4-20 IQ come equipped with an automated calibration feature
which allows the unit to be calibrated without manually
adjusting any potentiometers. Just apply gas and the 4-20
IQ will do the rest. It couldn't be easier! Interfacing
with the 4-20 IQ is accomplished by using a magnetic wand
to activate magnetic switches located on the front panel.
Thus, all functions can be performed with removing any covers,
meaning there's no need to declassify an area being monitored.
The 4-20 IQ can be used with any of IST's sensor technologies:
infra-red (IR), solid state, catalytic bead, or electrochemical.
