The 1-channel temperature measuring amplifier IM34-11Ex-CI/K60 is designed to evaluate the temperature-dependent changes of

Ni100/Pt100 (RTD), thermocouples (TC) types

B, E, J, K, L, N, R, S and T or low voltages in

a range of -160…+160 mV and to output them

as temperature-linear current signals of 0/4…

20 mA. Alternatively, RTDs in 2, 3 or 4-wire

technology can be operated at the input circuit

of the measuring amplifier. The Ni100/Pt100

input can either be used as external cold junction compensation for the thermocouple or as

independent measuring input.

If the thermocouple leads are led up to a temperature measurement amplifier, we recommend to use the cold junction compensation

module IN IM 3-CJT from TURCK (ident-No.:

6900524). This way the maximum possible

accuracy is achieved. In order to increase the

measurement speed with fast temperature

changes on thermocouples, the device switches into the Fast Mode after 200 ms at the

very latest after a gradient of 200 µV/s has

been exceeded. Thereafter the cycle time of

the thermal voltage measurement is < 80 ms.

This means that no wire-break monitoring and

no measurement of the cold junction temperature will occur. After the gradient drops below

80 µV/s the device will switch back to Normal

Mode“.

NOTE: The temperature gradients in the table

are only approximate values for defined temperature ranges. For the precise determination of the temperature gradient the characteristic of the sensor in question and the associated operating point must be included.

The devices are parametrized and configured

via PC with the software tool Device Type

Manager (DTM). For this, connect the temperature measuring amplifier to the PC with

the 3.5 mm jack plug on the front. The readymade transmission cable can be ordered from

TURCK under the type name IM-PROG (ident

no. 6890422). The following settings can be

made with the DTM:

■ Measurement mode (RTD, TC, low voltage, line compensation)

■ Measuring point (32 freely selectable characters)

■ Temperature (°C or °F)

■ RTD connection mode (2, 3 and 4-wire

technology)

■ Cold-junction compensation (internla or

via external RTD) NOTE: If the thermocouple leads are led up to a temperature

measurement amplifier, we recommend to

use the cold junction compensation module IN IM 3-CJT from TURCK (ident-No.:

6900524).

■ Measuring range mapped on the power

source

■ Output current (0/4…20 mA)

■ Fault current (0 resp. < 20 mA)

The signals are transformed according to ITS

90/IEC 584 for thermocouples and according

to IEC 751 for Pt100 RTDs and provided temperature linear at the current output.

wire technology

starting with a thermal gradient of 200 µV/s

■ Parameterized using PACTware
