The PIE 311 / 311Plus automated universal RTD calibrator automatically detects 2, 3, or 4 wire RTDs. It can be used to calibrate and measure all RTD instruments and sensors, automatically indicating connections on the display to simplify hookups.
It is available as a single channel RTD (PIE 311) or double channel milliamp and RTD calibrator (PIE 311Plus). Both models are compatible with any smart transmitter, PLC, DCS, or multichannel recorder.
The PIE 311 / 311Plus features automatic output stepping for fast calibration. Choose between 2, 3, 5, 11 and 21 steps to automatically increment the output in 100, 50, 25, 10 or 5% of span. Then select the step time to match your system from 5, 6, 7, 8, 10, 15, 20, 25, 30 and 60 seconds.
