1 Introduction
This section provides an overview of the main features of the RPR-4000, including a full
description of all of the inputs and outputs available on the front and rear panels of the
instrument. Procedures to help the first time user to get started with the instrument are
also included.
Feature overview
Intended Use
The RPR-4000 is a high powered ultrasonic pulser and receiver system intended for use
by qualified laboratory personnel, primarily for NDT (non-destructive testing) and NDE
(non-destructive evaluation) applications.
The high power RF tone burst (up to 20 kW depending on model) provides the ability to
drive inefficient transducers such as EMATs (Electromagnetic Acoustic Transducers) or
high capacitance, low frequency piezoelectric transducers. This can enable the user to
make measurements that would be unachievable using more conventional
instrumentation.
Environmentally Tolerant Packaging
The internal volume of the RPR-4000 has been designed to divide the available space
into two sections; one for critical electronics and one for cooling air flow across heat
radiators. Outside air brought into the cabinet to circulate over the heat radiators is
exhausted out the rear panel; critical electronics are never exposed to the air brought in.
This means that the RPR-4000 is ideally suited for harsh industrial environments. High
efficiency zero-voltage-crossing switching power supplies are used for all DC voltage
requirements. All power supplies are fully shielded.
The RPR-4000 has been tested at full duty cycle in environments up to 100 degrees
Fahrenheit (38 degrees Celsius). If an over temperature condition should develop, an
automatic shutdown feature will be enabled.
