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

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).

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.
