13.3.2 Construction
The MB-OX-SE1 consists of the sensor and the special electronics separated by a gas-
tight NW40 clamp flange. The sensor is protected against physical damage by a protective
cage. The sensor leads are connected to the electronics by a vacuum-tight feed-through.
The electronics are contained in an airtight box mounted directly to the back of the NW40
flange.

Installation
The oxygen probe is mounted on an appropriate vacuum-tight NW40 flange by means of a
centring ring and a clamp. The plug connection to the control unit should not be made before
the whole box-system has been purged sufficiently with inert gas. The operation of the probe
