ITC4000 Series
A further way of approximating the relation between temperature and thermistor resistance is
the method according to Steinhart-Hart, described by the formula
with the Steinhart-Hart parameters A, B and C; T - temperature in K. To select the calculation
method and to enter the thermistor parameters, please refer to section
Thermistor settings .
3.1.9.2 Current Temperature Sensors AD590 or AD592
If a temperature/current transducer AD590 or AD592 is used as temper-
ature sensor, it has to be connected to pin 10 (-) and pin 11 (+) of the
17W2 mixed DSUB jack "TEC OUTPUT" (R16,
Operating elements at
the rear panel ) at the rear of the unit.
3.1.9.3 Voltage Temperature Sensor LM35
If the temperature/voltage transducer LM35 is used as temperature
sensor, it must be connected to pin 10 (out), pin 11 (+) and pin 12 (-)
of the 17W2 mixed DSUB jack "TEC OUTPUT" (R16,
Operating ele-
ments at the rear panel ) at the rear of the unit.
3.1.9.4 Voltage Temperature Sensors LM335, LM235 or LM135
If the temperature/voltage transducer LM135, LM235 or LM335 is
used as temperature sensor, it has to be connected to pin 10 (+),
pin 11 (also +) and pin 12 (-) of the 17W2 mixed DSUB jack "TEC
OUTPUT" (R16,
Operating elements at the rear panel ) at the
rear of the unit.
3.1.9.5 Platinum RTD Temperature Sensors PT100 or PT1000
Pin 3 and 4 of the DSUB Connector are the current source, Pin
10 and 11 are the voltage measurement pins for the 4-wire
measurement setup.
One connector of the sensor has to be connected to pin 4 and 11
and the other to pin 3 and 10 of the 17W2 mixed DSUB jack
"TEC OUTPUT" (R16,
Operating elements at the rear panel )
at the rear of the unit.
For optimum performance, use a separate wire for each pin of
the DSUB connector and connect the corresponding wires only at
the PT100 or PT1000, as close as possible to the sensor.
