PIE

Practical Instrument Electronics, sold as PIE, builds process calibrators, and the range here covers loop calibrators, temperature calibrators and pressure calibrators.

The line is aimed at instrument technicians who want a straightforward tool rather than a deep menu structure, which is why PIE units are common in maintenance shops. For loop work, confirm whether you need the calibrator to supply 24 V loop power, and whether HART communication is required alongside the analog signal. Check intrinsically safe certification if you work in classified areas.
