Multi-function loop calibrator uncovers hidden problems
Saelig
The portable PIE 850 Multifunction Calibrator (photo) is a handheld instrument that combines eight single-function calibrators (including a milliamp current calibrator, a voltage calibrator, a thermocouple calibrator, and more), legacy 10–50-mA capabilities, and advanced troubleshooting tools. The PIE 850 is capable of diagnosing common loop-control problems that are hard to find, says the company. Loop-diagnostic technology and the LoopScope feature show key loop parameters — such as current, voltage and resistance — at a glance. It is compatible with all common instruments, smart transmitters and PLCs with 14 types of thermocouples and 9 types of RTD tempearature sensors, says the company. This lightweight tool includes a backlit display for use in dark environments, a protective rubber boot and built-in stand, a hands-free carrying case and all test leads.— Saelig Co., Fairport, N.Y.
