HD 421 Pt 100-type platinum temperature sensors are characterized by long-term stability, precision over a broad temperature range and compatibility.
Main application area is the process technology.
Nominal Resistance R0
Tolerance
DIN EN 60751
1996-07
Tolerance
DIN EN 60751 2009-05
Order Number Plastic Box
100 Ohm at 0°C
Class B ( to 650 °C )
F 0.3 (to 650 °C )
32 208 228
Class 2B (to 850 °C )

The measuring point for the nominal resistance is defined at 4mm from the end of the sensor body.
Specification
DIN EN 60751
Temperature Range
-70 °C up to +850 °C
Tolerance Class B: -70 °C up to +650 °C
Tolerance Class 2B: -70 °C up to +850 °C
Temperature Coefficient
TC = 3850 ppm/K
Leads
Pt- wire
Lead Length (L)
6mm +1mm
Long-term Tests
1000h at 850 (energized, open)
smaller then the allowed deviation according to DIN B. 1000 h
at 650 °C (under current as clean MI-type) smaller then the
allowed deviation according to DIN B
Vibration Resistance
at least 40g acceleration with 8ms half sine
wave signal, depends on the installation
Shock Resistance
at least 100g acceleration at frequencies
from 10Hz up to 2000Hz, depends on the
installation
Environmental Conditions
Unhoused for dry environment only, Up to 650 °C in housings also
as clean MI-type possible, above 650 no reducing atmosphere,
free air admission necessary
Insulation Resistance
>100 M °C at 20 °C ; >2 M °C at 650 °C
Self Heating
0.2 K/mW
Response Time
Water current (v= 0.4m/s): t0.5 = 0.05s
t0.9 = 0.17s
Air stream (v= 2m/s): t0.5 = 3.3s
t0.9 = 13.0s
Measuring Current
20 °C max. 5mA; 850 °C max. 2.8mA
(self heating has to be considered)
Note
Other tolerances,values of resistance and wire lengths are
available on request.
