Opto 22's SNAP-AIRTD-1K Platinum Temperature Sensing
The SNAP-AIRTD-1K is a two-channel, isolated analog input module for use with 1000-ohm platinum resistance temperature detectors (RTDs). It has a nominal input temperature range of -200 ºC to +850 ºC (-328 ºF to +1562 ºF) and an input range of 0 ohms to 4000 ohms. The module has an average resolution of 0.042 ºC (0.16 ohms). Used primarily with RTD probes to provide temperature inputs, SNAP-AIRTD-1K module can also be used for making high-resolution resistance measurements.
