Ni1000 (TK5000), high-resolution, ID 9

4.3.11.1

Default Format

With the setting "Ni1000 (TK5000)", the I/O module converts the measured
resistance values of Ni1000 sensors (TK5000) into temperature values and
outputs the conversion results in degrees Celsius.
The temperature values are displayed at a resolution of 1 digit per 0.01 °C in one
word (16-bit). Temperature values below 0 °C are represented in two's
complement binary. As a result, 0 °C corresponds to the numeric value 0x0000
and 100 °C to the numeric value 0x2710 (dec. 10000).
The maximum number range viewable in one word in two's complement
representation ranges from −32768 to +32767. The number range used depends
on the sensor type set and the resolution of the process value. For the setting
"Ni1000 (TK5000)", the possible numerical range corresponds to the defined
temperature range of −50 °C to +150 °C and ranges from −5000 to +15000
accordingly.
