RTD Calibrators

PIE has an RTD calibrator to fit your needs from the PIE 510B single type RTD simulator  to the advanced troubleshooting capabilities of the PIE 311Plus. Have you had issues in the past where your RTD calibrator wouldn’t work with some of the instruments in your plant? Our RTD calibrators are guaranteed to be compatible with all process RTD inputs including all brands of smart temperature and multivariable transmitters, PLC input cards, DCS systems and multichannel recorders.

PIE RTD calibrators are the only models with patented automatic detection of 2, 3 and 4 wire RTDs! All the RTD calibrators have fuse-less protection, rugged design, and long battery life. The PIE 311, 311Plus and 525B display in °F and °C along with the Ohm value from the temperature vs. resistance RTD tables.

The PIE 311Plus adds a FULL function milliamp calibrator plus it reads and sources 12 RTD types. It also includes PIE’s patented Leak Detection to find hidden problems in 4 to 20 milliamps loops.

The PIE 525B sources and measures 12 RTD types along with 14 thermocouple types. Additional features on the PIE 525B include high resolution to 0.01°, automatic detection of 2, 3 and 4 wire RTDs, and can display the excitation current used by the RTD instrument to measure an RTD sensor.

The PIE 525Plus adds a full diagnostic milliamp calibrator to the PIE 525B. Standalone RTD & Thermocouple transmitter calibration is possible with the simultaneous display of the output temperature while powering up the transmitter and displaying the output milliamp reading. Uniquely measures the resistance of a thermocouple sensor while indicating the temperature of the probe. It also includes PIE’s patented Leak Detection to find hidden problems in 4 to 20 milliamps loops.
