  4. PIE 434 Automated Diagnostic 4-20 mA Calibrator

    The Practical Instrument Electronics (PIE) 434 automated diagnostic 4-20 mA calibrator allows you to check, calibrate and measure all of your current signal instruments in a 4-20 mA DC loop. It can be used at any access point in your loop. You can calibrate recorders, digital indicators, stroke valves or any instruments that get their input from a 4-20 mA loop. Quickly diagnose ground fault and current leakage with the PIE 434 automated diagnostic 4-20 mA calibrator's loop diagnostic technology. PIE 434 calibrators also feature automatic output stepping and ramping. Press and hold the dial to automatically step from 4-20 in two, three or five steps or choose a continuous ramp.

  5. PIE 535 Voltage Current Calibrator

    Practical Instrument Electronics (PIE) Model 535 brings you the features of the original Model 532 for 10-50 milliamp process loops. On power up you can select 4-20 or 10–50 mA. The EZ-Dial™ knob and EZ-Check™ switch are all that's needed to make quick adjustments or set 0% or 100% of full scale. The EZ-Step™ button provides one-handed stepping. Automatic stepping and ramping modes allow hands-free testing and calibration of the process loop with HIGH accuracy and repeatability designed in collaboration with Nuclear plants. The model 535 offers the optional analog output of 10mV/mA proportional output for connection to chart recorders and data loggers. With the Model 535, calibration is easy as PIE.

  6. PIE 541 Frequency Calibrator with Totalizer

    The Practical Instrument Electronics (PIE) Model 541 is the best tool for calibration, test, and diagnosing turbine meters, frequency counters, vibration systems, tachometers, flow meters, vortex shedders, integrators, and any other Frequency devices in the shop, plant and/or field. The Model 541 brings all the features you would expect from a frequency calibrator and times new romanaving new ones. The Model 541 comes with an LED indicator showing gate time for easy trigger level adjustment. Make adjustments with the EZ-Dial™ knob or test limits with the dual action EZ-Check™ switch. Save hours of troubleshooting time on problems when compared to other calibration methods. When calibrating a totalizer, the PIE 541 eliminates the need of a stop watch. This calibrator will automatically stop when the selected number of pulses has been sent to the totalizer. Select from 6 different frequency ranges or select totalize to source or measure pulses within a selectable time.

  7. PIECAL 334Plus with Leakage PIECAL 334Plus with Leakage

    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.
