Purpose
This range of sensors is designed to detect a particular gas depending on the type
of sensor used.
Operating principle
The measurement sensor converts the target gas into voltage or current. This
electrical parameter is:
❧either conducted directly via a connecting cable to a dedicated central
measurement unit (as with the OLC100 explosimeter) that operates on the
principle of the Wheatstone bridge. Such a measurement unit is available in
the OLDHAM range.
❧or amplified, corrected for temperature, linearised, and converted to a 4-20 mA
signal (as for the OLCT100) and conducted via a connecting cable to a
centralized unit (measurement unit or industrial automation system).
