Same-day response on quotes. ISO/IEC 17025 accredited calibration available.
Overview
The PIECAL 211 checks and calibrates RTD instruments and measures RTD sensors directly in °C or °F—no decade box or resistance tables required. It works with Platinum 100 (α = 3850, 3902, 3926) and 1000 (α = 3850, 3750) Ω, Copper 10 & 50 Ω, and Nickel 120 Ω, and can also function as a decade box from 0.00 to 401.00 Ω and 0.0 to 2001.0 Ω.
Set any temperature to within 0.1° with the digital potentiometer dial, store three values for instant EZ-CHECK™ recall, and auto-step the output in 2, 3, 5, 11, or 21 steps (100% down to 5% of span) with selectable step times. Connect directly to RTD inputs on smart transmitters, PLCs, DCS, and multichannel recorders—including instruments with pulsed excitation currents.
Patented connection detection helps troubleshoot 2-, 3-, and 4-wire RTD sensors and find broken wires. The handheld unit includes a rubber boot, tilt stand, and backlit display. Made in the USA with a NIST-traceable Certificate of Calibration.
Features (PIE)
- Accuracy: ±(0.025% of reading + 0.05 Ω), with resolution to 0.1 °F and °C.
- RTD curves (source and read): Pt 100 Ω (1.3850, 1.3902, 1.3916, 1.3926), Pt 1000 Ω (1.3850, 1.3750; Pt 1000 limited to 266.0 °C / 511.0 °F), Cu 10 and 50 Ω, Ni 120 Ω, plus 0.00 to 2001.0 Ω. PIE offers custom ranges on request.
- Wire detection: patented automatic detection of 2-, 3- and 4-wire connections finds broken wires; all connections are shown on the display.
- Compatibility: PIE states it works with smart transmitters (including Rosemount and Honeywell), PLCs, DCSs, multichannel recorders and other pulsed-excitation devices.
- Speed: three EZ-CHECK outputs, a two-speed EZ-DIAL knob and automatic stepping for finding trip points.
- Display and power: backlit display; four AA batteries, changed without tools.
