4.1.9 PRT/RTD Inputs
The S600+ supports three Platinum Resistance Thermometer
(PRT)/Resistance Temperature Detector (RTD) inputs. These inputs
are suitable for Class A, 4-wire PRT devices that conform to the BS
EN 60751:1996 standard. The temperature measurement range is –100
to +200°C (–148 to +392°F). The S600+ supports three styles of
PRT/RTD probes:
DIN (coefficient of 0.00385 ohm/ohms degrees Celsius).
American Standard (coefficient of 0.003926 ohm/ohms degrees
Centigrade).
Calendar Van Dusen equations (used to support newer curves
based on the user A, B, C, and R0 coefficients).
The DIN 43760 selection is typical in Europe and common in the
United States, while the American Standard selection coefficient
(alpha) is still common for circumstances where a slightly purer
platinum is used to effect a higher absolute accuracy. You use the
Config600 software to configure the style of PRT/RTD input.
