Datalogging Wall Thickness Gauges

PZX-7 DL Series

Range with Standard Delay Line Transducer
0.0060″ – 1.000″ / 0.150 – 25.40 mm

Range with Contact Transducers
up to 36.00″ / 915.0 mm

The PZX-7 DL series gauges are basic single element precision gauges and equipped with a variety of measurement modes to address a number of potential applications.

They can use both high and low-frequency transducers with a variety of diameter options. Both models have USB-C connectivity, with and without data storage, and serial over USB-C using a CDC class.

  • Large, backlit LCD display retains last reading.
  • Includes NIST Traceable Calibration Certificate.
  • IP 65 Rated for protection even in the toughest field conditions.
  • Scan mode, 100 readings/sec. Probe is slid over a large measuring area, the minimum thickness during the "scan" will be displayed.
  • Can be used with both Single Element Delay Line and contact transducers (5 to 20MHz).
  • LCD shows Thickness Value, Velocity Setting, Gain Setting, Stability & Battery Indicators, Scan Mode, Zero and units.
  • Calibrate to a sample of known thickness which automatically calculates the optimal acoustic velocity.
  • Built-in datalogging for 10,000 data values stored in up to 40 batches with 250 values/batch with USB Output.
  • Powered by: 120MHz FPGA timing & 100 volt spike pulser.
  • Measure Modes: Pulse-Echo (P-E), Echo-Echo (E-E), Interface Echo (I-E) and Plastics (PLAS).
