Platinum Resistance

Drawing
Platinum Resistance

Specification
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) F 0.6 (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°c (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 in housings also as clean MI-type possible, above 650 no reducing atmosphere, free air admission necessary
Insulation Resistance >100 MΩ at 20°c; >2 MΩ 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.
