Introduction
Platinum-chip temperature sensors belong to the category of temperature sensors that
incorporate thin-film techniques. They are produced at JUMO under clean-room
conditions using state-of-the-art technology. A platinum layer, which constitutes the
active layer, is sputtered onto a ceramic substrate and subsequently formed into a
serpentine structure by a photolithographic procedure. Afterwards, a laser trimming
process is used for fine calibration. After calibration, a special glass covering layer is fused
onto the platinum serpentine, as a protection against external effects and for insulation.
The electrical connection is made through contact areas to which the connecting wires
are bonded. Depending on the version, the connecting wires may consist of different
materials and may, within certain limits, also have varying lengths and diameters. A further
glass layer that is applied to the contact area fixes the connecting wires and additionally
provides strain relief.
A large variety of PCA style platinum-chip temperature sensors can be supplied ex-stock
as Pt100, Pt500 or Pt1000 temperature sensors. Special nominal values can be produced
on request. High-resistance platinum-chip temperature sensors in small sizes are also
available. And, thanks to their low mass, very fast response times are achieved.
Furthermore, they are outstandingly resistant to shock and vibration when installed and
fixed. The operating temperature depends on the particular version, but generally covers
-70 to +600°C. However, these platinum-chip temperature sensors can also be used with
temperatures far below -70°C, provided that shifts in the nominal value and hysteresis
effects, which may occur within certain limits, can be tolerated.
Most temperature applications in the market make use of platinum-chip temperature
sensors as the active component for acquiring temperature. Typical application areas can
be found in HVAC, medical and laboratory technology, white goods, automobiles and
utility vehicles as well as in machinery construction and industrial engineering.
Technical publication
This revised edition takes account of altered
standards and recent developments. The
new chapter “Measurement uncertainty”
incorporates the basic concept of the
internationally recognized ISO guideline
“Guide to the expression of uncertainty in
measurement” (abbreviated: GUM).
In addition, the chapter on explosion
protection for thermometers has been
updated in view of the European Directive
94/9/EC, which has been in force since 1st
July 2003.
