WARNING!
Before installation, usage and operation, ensure that the appropriate temperature
transmitter/switch has been selected in terms of measuring range, design and specic
measuring conditions.
Non-observance can result in serious injury and/or damage to
the equipment.
WARNING!
Observe the working conditions in accordance with chapter 3 “Specications”.
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
The temperature transmitter/switch is used to convert temperature into an electrical signal indoors and
outdoors.
The instrument has been designed and built solely for the intended use described here, and may only
be used accordingly.
The technical specications contained in these operating instructions must be observed. Improper
handling or operation of the temperature switch outside of its technical specications requires the
instrument to be taken out of service immediately and inspected by an authorized NOSHOK service
engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended
use.

Risk of injury should qualication be insu󰀩cient!
Improper handling can result in considerable injury and damage to equipment.
The activities described in these operating instructions may only be carried out by skilled
personnel who have the qualications described below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training, knowledge
of measurement and control technology and on their experience and knowledge of country-specic
regulations, current standards and directives, are capable of carrying out the work described and
independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.
2.3 Special hazards

|T| is the value of the temperature without consideration of the sign.
The actually achievable accuracy is signicantly determined by the mounting situation (immersion
depth, sensor length, operating conditions). This is especially the case for large temperature gradients
between the environment and the medium.

1) The permissible ambient temperature is limited to -4 °F to 176 °F (-20 °C to 80 °C) at the “-20 - 120 °C” measuring range.
At high medium or ambient temperatures, ensure by suitable measures that the instrument case
temperature does not exceed 176 °F (80 °C) in continuous operation (the temperature is measured at
the hexagon of the process connection).
At medium temperatures above 176 °F (80 °C) the thread must not be immersed into the medium.

4. Design and function
4.1 Description
By means of a measuring element (Pt1000) and by supplying power, the prevailing temperature is
converted into a switching signal or an amplied standardized electrical signal via the change in
resistance of the measuring element. This electrical signal varies in proportion to the temperature and
can be evaluated accordingly.
4.2 Scope of delivery
Cross-check scope of delivery with the delivery note.

17
5.1 Transport
Check the temperature transmitter/switch for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in installation
site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -4 °F to 176 °F (-20 °C to 80 °C)
■
Humidity: 45 - 75 % relative humidity
WARNING!
Before storing the instrument (following operation), remove any residual media. This is
particularly important if the medium is hazardous to health, e.g. caustic, toxic, carcinogenic,
radioactive, etc.

6. Usage, operation
6.1 Mounting
Required tool: Open-ended spanner (spanner width 27)
■
The sealing faces at the temperature transmitter/switch and the measuring point must always
be clean.
■
Only screw in, or unscrew, the instrument via the spanner ats.
Never use the case as a working surface.
■
The correct torque depends on the dimensions of the process
connection and the sealing used (form/material).
■
When screwing in, do not cross the threads.
■
The instrument must be grounded via the process connection.
■
Attach the connector and screw it in hand-tight.
Seal
Correct sealing of the process connections with parallel threads at the sealing face must be made
using suitable at gaskets, sealing rings or NOSHOK prole sealings. The sealing of tapered threads
(e.g. NPT threads) is made by providing the thread with additional sealing material such as, for
example, PTFE tape (EN 837-2).

6. Usage, operation
Compression tting
1. Screw the compression tting (1) into the process connection and
tighten.
2. Insert the tapered side of the ferrule (2) into the tting and screw on
the union nut (3) hand-tight.
3. Insert the temperature transmitter/switch into the tting and maintain it
at the required immersion depth. Tighten the union nut (3) with approx.
50 Nm.
4. Optional
Check the assembly: Loosen the union nut. The ferrule is rmly
connected to the sensor tube.
