Ni1000 TK5000

The 750-461/000-009 version calculates the resistance values of Ni1000-TK5000
sensors and outputs the data as temperature values. The temperature values are
displayed at a resolution of 1 digit per 0.1 °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
0x03E8 (dec. 1000). The possible numeric range corresponds to the defined
temperature range of -30 °C to +122 °C for type Ni1000 TK5000 sensors.

Process values below 0 °C are represented in two's complement binary.
The measured value can exceed a decimal range of -300 to +1220 before
limitation takes effect.
