Sensor Scientific, Inc. Platinum Thin Film RTD Elements are fabricat-
ed using state-of-the-art thin film processing techniques, resulting in
an element of exceptional quality and stability. The wide choice of
resistance, tolerance, and size options allows for complete design
flexibility.
RTD elements are available with extension leads, and incorporated in
complete temperature probe assemblies. Please contact Sensor
Scientific for additional information.
Assemblies:
Generally, thin film RTD elements are incorporated into some type of
assembly for protection. Extension leads may be attached via solder-
ing, crimping, brazing or welding. The attachment method must be
capable of withstanding the intended
maximum operating temperature.
The following precautions must be taken when incorporating the
element into an assembly:
1) Avoid straining the element leads.
2) If extension leads are attached via soldering or brazing, all flux
residue must be removed.
3) The resistance of extension leads must be taken into consideration.
Resistance value at 0°C calibrated 1mm from end of lead wire.
4) If elements are encapsulated in a potting compound, insure that
the compound will not induce pressure loads, resulting in a strain-
gage effect.

The permissible deviations for platinum resistance elements
are determined by the following equations (in accordance with
IEC 751,2: 1995- 07 [DIN EN 60751: 1996-07]):
Permissible deviation in °C = ±(0.15 + 0.002 [t]) for Class A
Permissible deviation in °C = ±(0.3 + 0.005 [t]) for Class B
Where [t] is the temperature value (in °C)
Deviations in °C apply to all nominal resistances; deviations in
Ω
only to 100
Ω.
For nominal resistance values other than 100
Ω
the deviation
values in
Ω
must be multiplied by the factor R0 X 10
-2
.
Other tolerances are available

Nominal Resistance: 100 ohms @ 0°C
For Nominal resistance values other than 100
Ω
@ °C resistance
values from the table are corrected using the equation R 0 X10
-2
where R0 =
nominal resistance at 0°C.
