The moduler design of HF400 & HE900 makes it compatible with other Ultrasonic instrumentation and allow great flexibility when configuing system for a particular application. HF400 and HE900 Pulser-receivers are ideal bases for a wide variety of ultrasonic systems with a particular emphasis on high frequency and low frequency applications respectively. These are versatile stand alone instruments with high energy broadhand parameter. They feature front panel controls that permit quick and easy adjustment of pulse energy, pulse repetition rate, waveform damping and receiver gain attenuation. The pulser-receivers can be used with DW1000 delayed window module for a spectrum analyzer to measure frequency dependent material properties. They can also be used with 4503 module for material characterisation. When combined with an oscilloscope and appropriate transducers, the pulser receivers can be used for flaw detection, thickness gauging and sound velocity - measurements. HF400 Pulser receiver is suitable for high frequency application while HE900 is recommanded for highly attenuative and
low frequency applications. ROOP ULTRASONIX also offers other custom designed Pulser receivers for specific
applications. |
