Page 7: Description And Operation Of The Instrument
PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS 1.1 THE INTENDED USE OF THE INSTRUMENT 1.1.1 Intended use and operation range Thickness gauges are pocket-type portable ultrasonic gauges of general purpose. The instruments are designed to perform wall thickness measurements of boilers, containers, pressure-op- erated vessels, hull plates and other items made of black and non-ferrous metals, as well as small-diameter metal and plastic pipes (from 20 mm) with even and corroded surfaces with roughness Rz160 and minimum bending radius from 10 mm. -

PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS 1.3 INSTRUMENT DESIGN AND OPERATION PRINCIPLE 1.3.1 Instrument Design А1207 Ultrasonic Thickness Gauge is a pocket-type one-piece case (Figure 1) with a built-in accumu- lator battery and a built-in single element transducer. On/Off key Digital display Capsule of the piezoelectric... - Page 11 PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS The design of the instrument allows for the replacement of the worn-out capsule of the built-in transducer by means of unscrewing the tip detaching the transducer capsule from the instrument without extra tools (see 3.3). key is used to: Thickness Accumulator...
- Page 12 PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS 1.3.2 Operation Principle The instrument measures the time of the double movement of ultrasonic pulses through the object being inspected from one surface to another. This time is converted to the thickness value using a known velocity value.

Page 13: Intended Use
PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS 2.1 OPERATING RESTRICTIONS The instrument is designed to be operated under conditions listed in the Chapter 1.1.2. 2.2 FACTORS INFLUENCING THE OPERATION OF THE INSTRUMENT AND ACCURACY OF THE READINGS 2.2.1 State of the surface Loose or exfoliating rust, corrosion or dirt on the surface of the object to be tested can influence the transmission of the ultrasonic sound in the material. - Page 14 PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS results. The measurements can be executed through the thin paint layer (0.1-0.3 mm). At that, the result of the measurements will include the thickness value of the paint layer. If there is a thick layer of paint on the surface or the paint started to pill off, then remove it since the thick paint layer reduces the signal and can produce a false echo resulting in false measurement results.
- Page 15 PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS as possible, do not apply strong pressure and use clean contact grease only on the pre-cleaned surface. The instrument's readings when the transducer is leaning from the middle position will be increased a little. The minimum steady reading of the instrument contacting the tube’s wall with the middle of the working surface of the piezoelectric transducer will be considered the actual value of the measured thick- ness.
- Page 16 PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS 2.2.4 Acoustic properties of the material Some properties of the constructive materials can essentially limit the measurement accuracy and measurable thickness range, and they can as well increase the measurement error. 2.2.4.1 Sound dispersion In some materials (some types of stainless steel, cast-iron, composites) the sound energy is being dispersed (on the crystallite molding or on additions in the composites).

PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS 2.3 MAKING THE INSTRUMENT READY FOR OPERATION 2.3.1 Surface preparation Carefully clean the surface of inspected item from dirt, friable rust and scale prior to measurements. Apply sufficient amount of the lubricant to the area of inspection. 2.3.2 Switching On/Off the instrument To switch on the thickness gauge, shortly press the key. - Page 18 PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS The instrument will switch into the measurement mode. The horizontal strokes, the accumulator bat- tery state and the current measurement units are displayed on the screen (Figure 4). To switch off the thickness gauge, press and hold the key for more than two seconds. Note –...

- Page 22 PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS 2.3.4.4 Calibration mode Calibration mode consists of two stages. The first stage is the turning off the noise threshold. The second stage is the determination of the latency value in the transducer using the calibration sample included in the delivery kit.
- Page 23 PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS The instrument shall remain on the sample until the calibration is completed. The procedure is indi- cated by a countdown from “9” to “0” (“CLb9”, “CLb8”, … “CLb0 the procedure is indicated by a countdown from) (Figure 9).

Page 24: Maintenance
PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS The maintenance of the instrument includes cleaning it from dirt and dust and recharging the accumulator. 3.1 ACCUMULATOR BATTERY The rechargeable battery of the instrument is designed for operation over a wide range of tempera- tures. -
Page 25: Recharging The Accumulator
PenGauge Operation Manual ACOUSTIC CONTROL SYSTEMS 3.2 RECHARGING THE ACCUMULATOR The accumulator is charged via the external charger or from PC via USB. When the charger is connected to the instrument, the battery filling sign starts blinking. During the charging process the blinking symbol "moves" to the top of the battery sign. The period of charging depends on the discharge level. -
