Product Features:

  • 3-in-1 thermocouple, RTD, and full function milliamp calibrator: combines ALL the functions of a diagnostic milliamp calibrator with the accuracy of a laboratory thermocouple and RTD calibrator
  • Protect instruments & technicians from (potentially dangerous) catastrophic failures due to hidden loop problems
  • Quickly diagnose ground fault and current leakage often caused by water in conduits and junction boxes with patented loop diagnostic technology (US patent # 7,248,058)
  • Internal cold jnunction is accurate to ±0.05°C, traceable to NIST
  • State of the art accuracy and stability: Milliamp, thermocouple, and RTD sections were designed with state of the art components that are accurate and stable
  • Compatible with ALL process instruments
  • Connect directly to the RTD inputs of smart transmitters, PLCs, DCS and multi-channel recorders, and verify their outputs or displays
  • Find problems with troubleshooting tools: Troubleshoot thermocouple probes by measuring the resistance of the cables and sensing element, allowing you to replace high resistance probes before they burn out
  • Automatically detects 2, 3, and 4 wire RTD connections and indicates broken wires with patented technology
  • Verify heat treating uniformity survey recorders
  • Perform system accuracy tests
  • Capable of meeting the requirements of an AMS 2750 Field Test Instrument when certified by an accredited laboratory
  • Fits in the palm of your hand like a cell phone and weighs less then a pound
  • Automatic indication of connections on the display for simple hookups
  • Backlit display makes it easy to operate even in dark areas
  • Carry it without worry: includes a protective rubber boot and rugged, low profile switches

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.
