Technical Data; Installing The Oxygen Analyser - MBRAUN LABmaster pro sp Operating Manual

The analyser consists of the sensor, a box with integrated electronics and a gas-tight
DN40-KF clamp flange. The sensor is protected against mechanical damage by a pro-
tective cage. The sensor leads are connected to the electronics by a vacuum-tight feed-
through. The electronics are contained in a box mounted directly behind the DN40-KF
flange. The electronic measuring equipment is supplied with 24 V DC. It provides an out-
put voltage signal of 0 ... 10 V DC proportional to the oxygen concentration.
The heater of the sensor element is controlled by an additional input. If this external input
is not used, a jumper (bridge) must be placed on the electronics.
