  2. PIE 511B Ten Type RTD Plus Ω Simulator

    The PIECAL 511B simulates RTD resistances into all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. The PIECAL 511B is a superior replacement for decade boxes, so there is no need to lug a decade box around or be prone to error by reading RTD tables incorrectly. The PIECAL 511B has better accuracy and functions of many higher priced RTD calibrators.

  3. PIE 334+ Milliamp Loop Diagnostic Calibrator

    Have you ever replaced a "faulty" transmitter only to find the problem was somewhere else in the loop? And did you end up throwing the transmitter away after you fixed the other problem "just in case" the transmitter was faulty? If you find a loop where the transmitter is calibrated correctly but all the readings elsewhere in the loop have a fixed offset, this is due to Zero Shift. This zero shift is typically caused by some current in the loop bypassing the transmitter. This might be caused by ground faults, moisture or corrosion. If you have some loops that are erratic after it rains, there may be moisture present in a junction box where insulation has broken down. Turn on Ground Leak Detection and use the PIECAL 334Plus to power up the loop. Any current that isn't controlled by the transmitter or other current control element will be indicated as leakage on the PIECAL 334Plus display. The PIECAL 334Plus powers up the 2-Wire transmitter or loop and indicates the total current and the uncontrolled current. This provides information useful in troubleshooting loop errors.

    PIE 532 Loop Calibrator with Loop Diagnostics

    The Practical Instrument Electronics (PIE) Model 532 is the best tool for calibration, test, and diagnosing process loops. The Model 532 brings all the features you would expect from a loop calibrator and times new romanaving new ones. Make adjustments with the EZ-Dial™ knob or test limits with the Dual Action EZ-Check™ switch. Powerful ramping functions are only a button away on the Model 532. Save potentially hours of troubleshooting time on problem loops with the Model 532’s unique Loop Diagnostic Mode, only available at PIE! In Loop Diagnostic Mode, the loop current, voltage, impedance, AC voltage, and mode of operation are all displayed simultaneously eliminating the need of a DMM connection. Loop diagnostics is available in every mode of operation and truly is a diagnostic monitor, as parameters are continuously updated in real time. The smart diagnostic tool even indicates the most likely cause of loop failure! Loop Diagnostic features the ability to measure ground fault error caused by faulty wiring, flooded conduit and corrosion bridges.
