Product DescriptionThe Practical Instrument Electronics (PIE) Model 512 RTD Calibrator provides the highest performance and functions in its class by exceeding the accuracy and functions of many higher priced RTD calibrators. This is accomplished in a small package and is VERY simple to use.The Model 512 provides direct temperature calibration to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. It is compatible with pulsed systems and transmitters (like the Rosemount 3144.) A good trouble shooting tool is PIE’s Auto Detection of 2, 3, or 4 wire connections to RTD sensors which is PATENT PENDING. The PIE 512 is a superior replacement for decade boxes, eliminating the need for lugging around large equipment and the possibility of misreading RTD tables.
