for ultrasonic inspection systems


OPMUX-01/8 is particularly well suited for ultrasonic measurements as well as other kinds of measurements which needs many channels. Together with the card OPCON-01 and ultrasonic probes it could be used as complete ultrasonic testing device. Each channel has separate pulser&receiver. Technical data Channels: 8* Pulse amplitude range 50-360V* Max cable length between computer and the box 30m Connectors BNC: Transducers Trigger input Signal output DB15 Control signals/Power supply Features and Specifications Pulser circuit waveforms: The rising edge of the Trig In signal initiates the transducer charging process which takes about 3us. After this time a transistor switch which discharges the transducer is turned on (discharge time is about 20ns, but it can be longer, if the capacitance of the transducer is to large; the limit is reached, if the transducer is made from the standard ceramics, is 0.1 mm thick and has 8 mm diameter). Because of the very low output impedance of the device (<1 Ohm) and short discharge time the pulse generated with this device could be concerned as a real pulse answer for the most transducers.
