MAIN SPECIFICATIONS
2.1
Main parameters and dimensions
2.1.1 The thickness gauge consists of an electronic unit and piezoelectric
transducer.
2.1.2 The range of thickness measurements (for steel) varies from 0.6 to
500 mm.
2.1.3 The range of thickness measurements (for steel) by different transducers
corresponds to the values indicated in Table 1.
Table 1 – Transducer designations and measurement ranges
Transducer designation
.250" 5 MHz
.500" 5 MHz
.187" 7.5 MHz
.250" 7.5 MHz
.187" 10 MHz
2.1.4 The measurement range of ultrasonic waves propagation velocity varies
from 1250 to 10000 m/s.
2.1.5 Value of the smallest indication digit is as follows:
― for measuring the ultrasound propagation velocity – 1.0 m/s;
― for measuring the product thickness of less than 199.99 mm – 0.01 mm;
― for measuring the product thickness of more than 200.00 mm – 0.1 mm.
2.1.6 Time of the thickness gauge operation mode setup is up to 10 s.
2.1.7 Power supply of the thickness gauge is provided by three alkaline "ААА"
batteries (1.5 V) or nickel-cadmium cells (1.2 V).
2.1.8 Time of continuous thickness gauge operation on alkaline batteries and
with backlighting switched off is about 200 hours, on nickel-cadmium cells – about
120 hours.
2.1.9 Overall dimensions of electronic unit of the thickness gauge are no more
than 35 mm × 70 mm × 125 mm.
