Precautions
Please read the entire manual prior installing this
product. These instructions include information on
the TNS/TNF series capillary and rigid stem ther-
mometers. Refer to the part number label on the
instrument housing to verify the exact model number.
User's responsibility: The TNS/TNF series ther-
mometer are designed for use in a wide variety of
applications. It is however, the user's responsibility to
ensure the suitability of the device with respect to a
specific application. Additionally, it is the user's
responsibility to ensure the unit is properly installed
and tested prior to operation.
Proper Installation and Sealing: Always use a
proper thread sealant with all installations. Be sure
not to overtighten fittings. Test for leaks prior to oper-
ating the instrument.
Electrical Connections:
For units with optional adjustable switches, all electrical connec-
tions are made via a weather proof 90° angle connector plug on
the side of the indicator housing. Connections are made via num-
bered screw terminals inside the connector. It is recommended
that a multi-conductor jacketed cable be used. The outside diam-
eter of the jacket should be large enough to ensure that the
weather-tight cable gland on the plug can be tightened down
snugly.
Table 1 (back of page) lists all of the switch type codes and the
functional descriptions for each switch type. The switch type
code is stamped on the dial of the thermometer and is on the wir-
ing diagram which appears on the thermometer housing. Consult
the wiring diagram on the thermometer housing for pin assign-
ments for each switch.
Switch Adjustment:
For units which have optional switches, adjust the switch setpoint as follows:
Remove the switch adjusting tool by pulling it from the center of the 90° angle electrical connector.
Insert the tool into the adjusting stub at the center of the dial crystal. The setpoint indicators are the ones with the red tips.
Push the adjusting tool in against spring tension and rotate until the adjusting lever contacts the setpoint indicator at its
base.
Use the tool to rotate the setpoint indicator to the desired setpoint.
Re-install the adjusting tool into the rear of the electrical connector.

Wiring and Electrical: For units with switches,
check the current and voltage requirements for
the load to be controlled. Ensure that they do not
exceed the maximum specified switch ratings.
Temperature and Pressure: Under no circum-
stances should the maximum ratings of operating
temperature and pressure be exceeded. Doing so
can result in equipment damage and personnel
injury.
Material Compatibility: Ensure that the media
contacted parts are made of a material which is
chemically compatible with the process media.
Ensure that the housing material is compatible
with the ambient environment. Failure to do so
can result in equipment damage caused by chem-
ical attack.

  • Page 6: Operating Principle

    TNS/TNF 5. Operating Principle The measuring system of the gas pressure thermometer comprises probe, capillary tube and Bourdon tube in a casing. These parts form a unit. The complete measuring system is filled with pressurised nitrogen. A change in temperature causes a change in inner pressure in the immersion shaft. The resulting deflection of the Bourdon tube is transferred to the pointer through a pointer element.
  • Page 7: Contacts

    TNS/TNF 6.1. Contacts (only for case diameters 100 and 160 mm ) Description Electromechanical and electronic limit monitors serve to open and close electrical switching circuits depending on the position of the instrument display. They are suitable for fitting in casings with 100, 160 mm Ø. The limit values are adjusted from outside with a setting lock.
  • Page 8 TNS/TNF 6.1.2. Slow-action contacts These contacting devices switch free of delay in the same way as the motion of the actual-value pointer. They should be used where no contact loading is required and the instruments are not exposed to vibrations. Due to sparking, the contacting devices should not be used where there is a danger of explosion.
