1. Temperature sensor PT100 - freely positionable in the
chamber for load monitoring and registration
1.1 Functions
One of the two temperature sensors of the controller is a freely positionable temperature
sensor PT100. The PT100 sensor is plugged into the 4-pin LEMO connector on the right side
of the shutter box and placed in the interior of the climate chamber through the silicone feed-
through.
Thanks to the second temperature sensor, the programme sequence can be controlled in a
way keeping the programme from switching to the next ramp until the chamber load has
reached the desired setpoint temperature.
To control the temperature inside the chamber, the temperature value of the temperature
monitoring sensor is used. The monitoring function is fully maintained.
1.2 Displaying the temperature of the additional, freely
positionable temperature sensor PT100
Turn the turn control to the left until „SENSOR 1“ appears in the display. The temperature dis-
play shows the current temperature of the additional, freely positionable temperature sensor
PT100.
1.3 Display of the sensor temperature in the internal flash log
memory
RED: Interior temperature in the test chamber
YELLOW: Temperature of the freely positionable PT100 sensor (e. g. core temperature of
the test object)

configuration
Criterion for reached setpoint temperature
Without freely
positionable PT100 sensor
Temperature inside the chamber must have reached the set-
point temperature (± 2 K).
With additional, freely
positionable PT100 sensor
Temperature at the freely positionable PT100 sensor must have
reached the set ASF tolerance band; adjustment range (±0.5 to
±10 K).
