Application:
The resistance thermometer PTX is used for measurement of temperatures in all areas, where explosive
gas / air or dust / air atmospheres can occur.
This concerns application fields of chemical and energy industry as well as many other general application areas
of industry.
Function:
The resistance thermometer PTX can be mounted into pipes, containers or other facility parts by using various
process connections.
The protection tube of the resistance thermometer is the junction point to the measured medium.
By using a neck tube with the corresponding length at high medium temperatures, the temperature in the area of
the connection housing can be kept in the range of the permitted environmental temperature.
For highly vibration loaded operation areas a neck tube with a greater outside diameter can be used.
The connection housing is used for the connection of the temperature measuring resistances Pt-100 to an
evaluation electronic and is suitable for building-in of a head transmitter that is constructed for form B.
Inside the resistance thermometer the measuring insert is placed. This measuring insert represents the real
temperature sensor. In the built-in condition the tip of the measuring insert is pressed against the end of the
protection tube and guarantees by that the optimum heat transfer.
Inside the measuring insert tip the one or two temperature measuring resistors Pt-100 are integrated.
At the end of the measuring insert tube a mounting pate is fixed, by witch the measuring insert can be fastened
inside the device or on that an optional transmitter or terminal socket is or can be fixed.
