11.2 TEMPERATURE CONTROLLER
In standard version -H, or with option –H320/C temperature control is ensured by way of the capillary
tube thermostat which is built into the connection box and which has a regulation range between 0°C
to 180°C (-H) or 0°C to 320°C (-H320/C). Rated values can be set to a maximum 180°C resp. 320°C.
The temperature has an excess temperature limiter which permanently switches off the heating if the
set temperature is exceeded by 30°C. The heating can be switched back on again by pressing the
green RESET-button which is located below the aperture in the thermostats mounting.
The thermostat has a temperature failure alarm which activates a contact if the temperature falls 30°C
below the set temperature. This status alarm is located on the terminal strip as a potential-free switch
over contact.
If temperature control is to be achieved using external electronic equipment, a PT100 (a max. of two
can be built in) or an Fe-CuNi resp. Ni-CrNi thermoelement is provided as a temperature sensor.
M&C also supplies suitable temperature controller, e.g. Type 70304G (see data sheet 2-5.1) which
also can be mounted directly at the gas sample probe (max. ambient temperature +45°C).
11.3 SAMPLE TUBE AND PREFILTER POSSIBILITIES
Depending on the process gas temperature and composition, probe tubes made of different materials
are used with ¾" connections.

For more information about sample tubes see data sheet 2-1.1.0.6
To prevent condensation between sample point and heated gas sample probe or in case of conden-
sation in the area of the connection piece heated sample tubes made of stainless steel with flange
connection DN65 PN6 are used.
