CONNECTION OF CALIBRATING GAS
The dilution heated probe is provided with a check valve as standard, opening at pressures above
0.7bar.
In both versions, a pipe union DN4/6mm (1/4“
o
for 115V version) is available for connection of the
calibrating gas.

ELECTRICAL CONNECTION
Temperature setting of the SP2000H/DIL... probes takes place with a capillary regulator as standard.
The probe can also be provided with an optional PT100 or thermocouple. This requires the connection
of an external temperature controller.
W A R N I N G !
An incorrect mains voltage can damage the unit. Check the rating
plate for the correct voltage prior to connection!
The probe must be installed so that contact with live parts is ex-
cluded!
In any case we recommend the use of temperature resistant cable !
The alarm contact for under-temperature must be displayed!
In case of an under-temperature alarm (failure of probe heating or
sensor), the dilution gas and bypass gas supply (if equipped) must
be interrupted or serious probe damage will result. We recommend
that external solenoid valves to perform this function be wired into
the probe’s under-temperature alarm circuitry automatically.
Damage the probe’s internal components from plugging or corro-
sion resulting from the lack of use of the probe’s under-
temperature alarm are not covered by warranty.
N O T E !
For the erection of power installations with rated voltages up to
1000V, the requirements of VDE 0100 and its associated standards
and specifications must be observed.
A main switch must be provided externally.
The supply circuit of the unit must be protected by a fuse with the
correct rating (over-current protection); the electrical values are
shown in the technical data.
When installing the capillary regulator or PID controller at the sam-
ple point, the maximum permissible ambient temperature must be
observed (see 8.). If this limit is exceeded, a PID controller must be
installed externally and outside the temperature critical zone.
