2 Installation and Operating Instructions TTP x00

Safety information

Please read this manual carefully, and also take note of country-specific installation standards
(e.g. the VDE regulations in Germany) as well as prevailing safety regulations and accidents
prevention rules. For safety and warranty reasons, any internal work on the instruments, apart
from that involved in normal installation and electrical connection, must be carried out only by
qualified KROHNE personnel.

Items includes with supply

• Measuring instrument

• Hygienic adapter

• Installation and operating instructions

Product liability and warranty

Responsibility for suitability and intended use of these instruments rests solely with the operator.
Improper installation and operation of the instruments may lead to loss warranty.

In addition, the “General conditions of sale” forming the basis of the purchase contract are
applicable.

If instruments need to be returned to KROHNE, please note the information given on the last-but­one page of these instructions.

KROHNE regrets that it cannot repair or check your instruments unless accompanied by a fully
completed Service and Repair sheet.

CE / EMC / Standards/ Approvals

The product bears the CE marking on account of compliance with and application of the following
standards:

EMCG (89/336/EEC)

EN 50081-1 EN 55022 Class B
EN 61000-6-2 EN 61000-4-2 ESD 4/8 kV
EN 61000-4-3 HF radiated 10 V/m
EN 61000-4-4 Burst 4 kV
EN 61000-4-5 Surge 1 kV sym., 2 kV unsym.
EN 61000-4-6 HF cable 10 V

Installation and Operating Instructions TTP x00 3

1 Installation

1.1 Mechanical installation

• Use only the recommended sleeves or adapters. If other systems are used, no guarantee can
be given for proper functioning or leak-tightness.

• Do not use Teflon or paper gaskets for the hygienic process connections featuring a conical
seal.

• The tightening torque for the sleeve should be between 10 and 20 Nm.

1.2 Process connections

The hygienic weldable process sleeves are easy to weld into tanks and pipes. The marking points
to the centre of the future position of the cable gland or M12 connector. This form of assembly
allows installation in conformity with standards of hygiene (to EHEDG, FDA).

Various hygienic adapter sleeves (see Accessories) are available for fitting to other process
connections.

• Process connection G1/2“h is the hygienic standard connection with conical seal.

• For installation in small-diameter pipelines it is recommended to use the hygienic M12 system

(from DN 15).

• When using a sliding sleeve, please use the threadless variant. The clamp cone forms a
hygienic seal with the protective tube.

• A standard G1/2“ connection is available for applications with no hygiene requirements (e.g.
cooling water).

4 Installation and Operating Instructions TTP x00

2 Electrical connection

2.1 External signal converter

Terminals 1, 2 and 3, 4 are used for connecting up the Pt100 sensor. You can, as required,
connect up in 2-, 3- or 4-wire technology.

• The 2-wire connection should not be used when particularly high accuracy is required and
where the connecting cables are of longish length.

• When using a 3-wire connection, make sure that all wires have the same cross-sectional area.

The same options are available for the double Pt100, but if connection is made with an M12
connector then only the 2-wire connection may be used.

Installation and Operating Instructions TTP x00 5

2.2 With integrated signal converter

Terminals 1 and 2 are used for the infeed via a 4...20 mA current loop. As supply voltage, at least
8 V must be available at the module. Do not use any voltage supply higher than 28 V. The pin
assignment for the M12 connector is shown in the connection diagram. Please pay regard to the
respectively valid wiring regulations.

2.3 Start-up

• Check the leak-tightness at the sleeve.

• Make sure that the cable gland is tight or, as the case may be, the M12 plug connector is

properly screwed down.

• After powering the unit, check for correct functioning.

2.4 Operator control

External signal converter

Refer to the directions supplied with the evaluator. Set the measuring range and type of
connection at the unit.

With integrated signal converter

You can program the measuring range with the programming adapter, available as an accessory,
and the associated PC software. Refer to the operating instructions supplied with the
programming adapter.

6 Product description

6.1 Applications

The screw-in temperature sensors of the series “with connection head“ are designed to measure
the temperature in all processes where high accuracy and ease of handling are what count. The
various mounting systems and adapters available enable the optimum choice to be made for your
application.

6.2 Functional principle

All temperature sensors of this series feature a Pt100 chip as the sensor element. A platinum
meander applied to a ceramic substrate is trimmed such that its electrical resistance at 0°C is
exactly 100 ohms. This resistance increases by 0.38 ohm for each 1 Kelvin temperature rise. The
exact resistance performance is described in the DIN EN 60751 standard. For our temperature
sensors we use without exception the high accuracy class “A“.

6.3 Construction

The various weldable process sleeves are made of stainless steel to allow installation in
conformity with hygiene requirements. Various evaluation modules are available for evaluation of
the Pt100 signal (see Accessories). A signal converter integrated into the stainless steel
connection head provides a 4...20-mA standardised signal locally, which can be transmitted noise­free direct to the analogue input of an SPC or PLC. It is also possible to install a transmitter for
Profibus PA.
The Pt100 sensor is housed in a rugged 6 mm protective tube of variable length and made of
V4A. Due to the special type of thermal coupling, our temperature sensors achieve very fast
response times. Tapered sensor tips are also available for even higher requirements.
