422Plus PIE Diagnostic Thermocouple & mA Calibrator

422Plus – Find Hidden Loop Problems with Ground Leak Detection

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 current in the loop bypassing the transmitter. This might be caused by ground faults, moisture or corrosion.

Turn on Ground Leak Detection and use the PIE 422Plus 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 calibrator’s display.

Typical problem found with Loop Diagnostics

422Plus
Here is a loop where a technician has just re-calibrated the transmitter but the control room still sees a problem. The problem started just after a rainstorm.
422Plus
Using a PIE 422Plus to power the loop the technician detects a leakage of 0.51 mA – the same offset seen in the control room. He walks the loop and opens a junction box releasing a stream of water. The loop is again in control. Clink on the link below to see a video demonstration of Loop Diagnostics in action.

422PLUS Operating:

Two Calibrators in One!
Calibrate all your thermocouple instruments AND your milliamp loops with the PIE 422Plus. It has all the functions of a 14 type thermocouple calibrator and can source 0 to 24 milliamps or simulate a two wire transmitter like a milliamp calibrator. You may also perform stand alone calibrations of two wire transmitters by simultaneously supplying the thermocouple input signal while supplying the 24 volts to power up the transmitter and monitoring the milliamp output signal. Powers HART™ transmitters with built-in 250 ohm resistor simplifying hookups with HART communicators.

 

Troubleshoot loop problems
Quickly diagnose ground fault and current leakage with the patented loop diagnostic technology (US Patent# 7,248,058)

 

Calibrate directly in temperature (°C & °F)
Stop carrying around a millivolt source and thermocouple tables. The PIECAL 422Plus works with the thermocouples you use including types J, K, T, E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) and P (Platinel II). Easily set any value quickly to within 0.1° with the adjustable “EZ-DIAL” plus store any three temperatures for instant recall with the EZ-CHECK™ switch. You may also calibrate from -13.000 to +80.000 mV. Connect your thermocouple and the PIE 422Plus measures the probe in degrees C or F. Secondary display shows the millivolt value corresponding to the thermocouple temperature.

 

Calibration Lab Accurate & Stable
The internal cold junction thermistor is accurate to ±0.05°C and is traceable to NIST. The sensor is thermally bonded to an isothermal mass including brass blocks with screw terminals for connection of bare thermocouple wires along with a miniature thermocouple connector for fast connections. An extremely stable voltage reference and low drift components make it more accurate than most other handheld & bench-top thermocouple calibrators.

 

Verify Heat Treating Uniformity Survey Recorders and perform System Accuracy Tests
The PIE 422Plus is capable of meeting the requirements of an AMS 2750 Field Test Instrument when certified by an accredited laboratory.

 

Checkout all your 4 to 20 mA loops & instruments
With the built-in milliamp calibrator you can check, calibrate and measure all your current signal instruments in a 4 to 20 milliamp loop. It can be used at any access point in your loop. Source & Read 0.000 to 24.000 mA, Simulate a 2 Wire Transmitter or use the PIE 422Plus to simultaneously power your 2 Wire Transmitter and measure its output while simulating the sensor input.

 

Easy to use in the Plant, Field or Shop
With the PIE 422Plus you can check & calibrate all your thermocouple instruments, measure thermocouple Sensors, and calibrate 4 to 20 milliamp instruments. Automatic indication of connections on the display for simple hookups. Carry it without worry – it comes protected with a rubber boot and rugged, low profile switches. Easy to operate even in dark areas with the back-lit display.

 

Fast calibration with automatic output stepping
Choose between 2, 3, 5, 11 and 21 steps to automatically increment the output in 100%, 50%, 25%, 10% or 5% of span. Select the step time to match your system from 5, 6, 7, 8, 9, 10, 15, 20, 25, 30 and 60 seconds.
