PIECAL 850 10-50 mA Multifunction Process Calibrator with Loop Diagnostics


The Compact PIECAL 850 from Practical Instrument Elestronics (PIE), can replace a whole toolbox of single function devices
  • milliamp
  • Voltage
  • Thermocouple
  • Ohms
  • RTD
  • Hz (Frequency)
  • pH
  • Pressure (via optional external pressure module)

The intuitive EZ-DIAL Double Click Menu makes it easier to setup than many other multifunction calibrators and uses the same menus as the single function PIECAL Evolution Calibrators. Icons on the display indicate where to plug in the test leads.

  • Use it as a milliamp and voltage calibrator
    Source 0.000 to 24.000 mA, 0.000 to 50.000 mA, 00.00 to 10.250 VDC, -20.000 to 99.999 mV and -500.00 to 999.99 mV
    Read to 24.000/52.000 mA, 0.00 to 60.00 VDC, +/- 99.999 mV and +/- 999.99 mV
    Simulate 2 Wire transmitters
    Power up transmitters and loops(24 VDC @ 20 mA; 40 VDC @ 50 mA) with built in power supply
    Simplify HART hook ups with built in 250 ohm resistor
  • Check all loop parameters at once with the LoopScope
  • Simultaneously displays current, voltage and resistance to let you know the condition of a live loop. Finds problems with power supplies & loops with too many loads. Patented by PIE!
  • Calibrate directly in temperature (°C & °F)
    The PIE 850 works with the instruments you use.
    Thermocouple types J, K, T, E, R, S, B, N, G, C, D, L (J DIN), U (T DIN) and P (Platinel II)
    RTD types Pt 100 Ohm (3850, 3902, 3916, 3926) & 1000 Ohm (3850)
    Copper 10 & 50 Ohm, Nickel 110 and 120 Ohm
  • Checkout flow and vibration systems
    Source & read frequency to 2000 CPM (Counts-Per-Minute), 999.99
    Hz, 9999.9 Hz, & to 20.000 kHz
  • Troubleshoot loop & wiring problems
    Beep out connections with the built-in continuity checker
  • Simulate pH probes into transmitters & analyzers
    Source from 0.000 to 14.000 pH @ 25°C (77°F) corresponding to +414.12 to -414.12 mV
  • Measure pressure with optional pressure modules
    32 modules for gauge, differential, compound and absolute pressure
  • Easy to read
    Turn on the backlight & easily see the display in dark areas of the plant
  • Quickly set any three outputs plus automatic stepping & ramping
    Easily set any value quickly with the adjustable “DIAL”; store any three output settings for instant recall with the EZ-CHECK™ switch.
    Choose between 2, 3, 5 & 11 steps to automatically increment the output in 100%, 50%, 25% or 10% of span.
    Select RAMP to smoothly increase and decrease the output between Zero and Span.
    Set step/ramp time to match your system from 5, 6, 7, 8, 10, 15, 20, 25, 30 and 60 seconds
  • Measure temperature sensors, frequency pickups, loop currents, voltage levels & pressures
    Check the values of your process sensors. Instantly recall MAX and MIN values to see process variability
