The PIE 525PLUS is a High Accuracy Diagnostic Thermocouple, RTD, and Milliamp Calibrator with Patented Current Leakage Testing.

The PIE 525Plus offers powerful troubleshooting tools that offer visibility to the health of your loop that is not possible with any calibrator brand on the market. Ground Leak Detection allows technicians to find and fix undetected problems before they cause quality issues or become catastrophic failures - producing poor product, injury, loss of life, or equipment damage. Common loop problems caused by moisture, corrosion and contamination left unchecked can lead to dangerous conditions that are easily avoided with the innovation technology in the PIE 525Plus.

Even the most common small errors caused by loop wiring issues can lead to inferior product, lost production time and risk to personnel. Intrinsically safe loops are protected by barriers only against extreme overvoltage and over current conditions but allowing small but significant ground faults to go undetected. PIE's unique and powerful Ground Leak Detection technology quickly and easily finds a fault that would otherwise go undetected. These undetected faults could lead to potentially disastrous outcomes.

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 a Zero Shift. This Zero Shift is typically caused by some of the current in the loop bypassing the transmitter. If you have some loops that are erratic after it rains there may be moisture present in a junction box or where insulation has broken down.

Only a PIE Calibrator with patented Ground Leak Detection can find all these hidden problems. Turn on Ground Leak Detection and use the PIE 525Plus to power up the loop. Any current that isn't controlled by the transmitter or other current control element will be clearly indicated as leakage on the PIE 525Plus display.

Ground Leak detection allows technicians to troubleshoot loop problems with ease and confidence - minimizing risk and maximizing process uptime.
