Description
The CTP5000 provides a full range platinum resistance
thermometers (PRTs) for use in every application from
standards calibration to site temperature measurement. If the
‘o the shelf’ range will not suit the needs the thermometers
can be supplied custom manufactured to almost any
specication.
WIKA also provide a range of standards resistors for use
when calibrating platinum resistance thermometers.
Using calibrated probes with a precise thermometer there
is a choice between storing the calibration data into the
memory of the instrument or if using ASL SMART probes for
ease of convenience, the calibration is stored in an electronic
memory chip located in the connector. Therefore moving the
SMART probe between channels or instruments is easy as
the calibration data is stored in the SMART-probe connector,
no need to enter the calibration data into the instrument
channel now being used.
Reference thermometer model CTP5000
For calibration, the test items and the standard thermometer
are brought to the same temperature in a temperature
conditioning unit.
As soon as a stable temperature is reached, the test items
are read or their output signals are measured (resistance,
thermoelectric voltage, standard signal) and compared with
the standard thermometer.
Using this comparison method, the measuring uncertainty
can be considerably reduced because not only the display of
the temperature conditioning unit is taken into consideration.

Options
With bare wires, DIN plug or SMART plug
With ASL's SMART connector on the probes,storing the data
is needed only once - in the connector! The calibration data
stays with the probe - permanently. It can even be used on
another read-out without any further action.
Viewed from top panel

The SMART connector saves time and reduces error. If there
are existing calibrated or uncalibrated probes, no problem,
ASL read-outs automatically register if a probe is SMART or
normal.
