PZX-7
Precision Ultrasonic Wall Thickness Gauge
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 is a precision ultrasonic wall thickness gauge designed for high-resolution measurements on thin-wall metal and plastics. It is packaged in a sturdy extruded aluminum housing which is sealed for excellent environmental protection assuring trouble-free use even in the toughest field and production environments.
The PZX-7 has measuring range in steel from 0.0060 to 1.0000 inch, (0.15 to 25.40 mm). Using a single element delay tip transducer, the gauges will measure thin materials and automatically remove any coatings in Echo-Echo Mode (E-E) as well as automatically switch to Interface Echo Mode (I-E)when measuring thicker materials, For measurement of plastics, the user would select Plastic Mode (PLAS) and use the option Graphite Delay Line Tip (p/n X-633-0000).
Additional Measuring Modes include Differential (DIFF) where a user sets a "nominal value" and the gauge displays the ± difference between then nominal and actual wall thickness, Alarm (user-set Hi/Low Limits) trigger Hi/Lo LED's when the measured values are out of tolerance and Velocity Mode
The PZX-7 can also be used with single element contact transducers for wall thickness measurements up to 36 inches (923 mm). Although the PZX-7 does not have any built-in memory, it can transfer single values (value on the display) via the USB port to a PC or compatible data collector. No Software is required.
Features

- Calibrate to a sample of known thickness which automatically calculates the optimal acoustic velocity
- USB Data output of single values for transfer to data collection devices (no internal memory)
- 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)
- Optional serial RS-232 or Bluetooth output
- Additional Modes Include Differential (from user-entered "nominal value"), Alarm (user-set Hi/Low Limits) and Velocity Mode
