Intrinsically-Safe Ultrasonic Wall Thickness Gauge
With the 1071-EX, measurements of wall thicknesses can be made quickly and accurately in the range of 0.03" to 15.7" (0.7 to 400 mm). There are three different probes available to cover this wide measuring range, each of which can be easily and conveniently changed inside the hazardous area.
- Standard Probe: 0.06" to 10" (1.5 to 250 mm)
- Mini Probe: 0.03" to 1" (0.7 to 25 mm)
- Low-Frequency Probe: 0.2" to 15.7" (5 to 400 mm)
Due to its compact size and operating time of over 200 hours, this easy to use instrument is essential whenever the continuous supervision of minimum wall thicknesses is required.
For example, it is possible to check the thickness of protective coats or for the erosion of pipe or tank walls even while the plant is operating.
By using the limit value guides, minimum and maximum values can be set and are registered by an audible signal.
The calibration functionality of the instrument means that adjustments can be made to compensate for the type of material being measured, this is done by one of two ways:
- Entering the sound velocity of the corresponding material
- Measuring a material with known thickness and adjusting the instrument to that reference
These adjusted parameters then stay in the memory even when switching off the instrument. Display resolution and sensitivity are also fully adjustable and as with all the other functions, are easily selected from the straightforward menu.
