The Practical Instrument Electronics (PIE) PIECAL 235 Process Voltage Calibrator features an intuitive EZ-DIAL Double Click Menu that makes it easier to setup than other calibrators. Turning on the backlight allows users to easily see the display in dark areas of the plant. Connection diagrams are indicated on the display for each function along with a labeled connector panel on the top.

Check Process Voltage Inputs

With the 235 Process Voltage Calibrator you can check, calibrate and measure all your voltage, millivolt and pH signal instruments in your plant. Source -500.00 to 999.00 mV, 1.000 to 5.000 V, -25.00 to 100.00 percent of 1-5 V; 0.000 to 20.000 V. The 20.000 range has an extended span to power loops with up to 1,200 Ohm loads with 24.000 Volt output.

Measure Process Voltages

The 235 Process Voltage Calibrator can measure from -500.00 to 999.00 mV, 0.000 to 5.100 V, -25.0 to 125.0 pervent of 1 to 5V; 0 to 20.000 V, 0.00 to 60.00 V DC. Use it to check loop power supplies, I/V converters, 1 to 5 Volt signals, and other voltages.

pH Simulator

Use the pH simulator to verify proper operation of pH devices before you place a probe into a calibrated buffer.

Power Your Loops with over 1,000 Ohm Loads

The 20.000 V range has an extended span of up to 24.000 Volts giving you a portable source for powering your loops.

Save Time Calibrating Recorders and Monitors in 4 to 20 mA Loops

Other brands of calibrators require that you break the loop to calibrate voltage inputs. With the PIE 235 you simply clip the test leads across the voltage inputs in a live 4 to 20 mA loop without disconnecting any wires.

Quickly Set any Three Outputs Plus Automatic Stepping and Ramping

Easily set any value with the adjustable "DIAL" plus store any three output settings for instant recall with the EZ-CHECK switch. 2, 3, 5 and 11 steps automatically increment output in 100, 50, 25 or 10 percent of span plus continuous ramp. Set step/ramp time to 5, 6, 7, 8, 9, 10, 15, 20, 25, 30 and 60 seconds.

Designed for You by Experienced Calibrator Manufacturers

The 235 improves upon other brands by including a rubber boot, backlit display with larger digits, higher accuracy and more ranges for flexibility.
