2.5.3 Integratable Measurement Value Logging
In the measurement and control workshop, a measuring instrument
is required for connecting the probe that measures thermo-
voltages, resistance and 4-20 mA standard signals and displays
them in degrees centigrade.
In combination with the calibrators of the CTD 9300 family, the
integratable measuring instrument CTI 9350 is a useful supplement
to your calibration equipment. The measuring instrument can be
integrated in the housing of the CTD 9300 calibrators. Order the
CTI 9350 directly or upgrade your device later on. We offer you the
choice. In the case of an upgrade, the front panel is simply replaced
in the works.
The temperatures of the two thermometers - of the reference and
the probe - can be displayed at the same time and simply compared
to one another.
The following can be connected as probes:
Resistance thermometers: Pt 100, Pt 500 und Pt 1000 in 2, 3 or
4 wire circuits
Thermocouples of the K, J, N, E, R, T, B, S, L and U types
4-20 mA power signals from temperature transducers, with and
without supply voltage
Temperature switches with "normally open" and "normally
closed" contacts.
The reference resistance thermometer is connected using a 7-pole
connector.
Three different connection possibilities have been provided for the
probe:
Binding posts for 4 mm connectors, spade connectors and
blank wires
Standard thermo-connector
Miniature thermo-connector
The 4 mm sockets (1, 2, 3 and 4) are generally used for connecting
the resistance thermometer, temperature switches and 4-20 mA
signals. All the three connection versions are available for
thermocouples.
