The SNAP-AIRTD-1K is a two-channel, isolated analog input module for use with 1000 ohm platinum resistance temperature detectors (RTDs). The module provides two channels of analog temperature input, with a nominal input temperature range of -200 to 850° C (-328 to 1,562° F) and an input range of 0 to 4,000 ohms. The unit has an average resolution of 0.042° C (0.16 ohms). Used primarily with RTD probes to identify temperature inputs, the unit can also be used for high-resolution resistance measurements. RTD probes are used by engineers and technicians to precisely measure temperatures in industrial furnace and refrigeration applications, HVAC systems, autoclaves or in any application requiring accurate measurement over a wide temperature range.
