At 7 updates per sec, Model AI-1500 executes automatic self-calibration, internal diagnostics, and measurement parameter validation. Two-wire transmitter with HART communications also quickly compensates for ambient temperature changes, variations in line voltage, and fluctuations in internal electrical component characteristics. It accepts almost any t/c or RTD. Input linearization is performed to ±0.05°C precision from input curves stored in onboard, nonvolatile memory. Instrument is suited for field mounting in explosion- or weatherproof enclosures, pipe mounting, and DIN rail-mounting for panel applications.
