Figure 2: Typical Source Holder Shutter Mechanism - Ohmart Vega W-4510 Technical Reference Hardware Manual

Introduction
The following statements describe the functions of the W-4510 Weigh Scale detector
assembly:
•
Mounts opposite the source holder
•
Inside the housing is a scintillation material
•
The scintillation material produces light in proportion to the intensity of its exposure to
radiation
•
A photomultiplier tube detects the scintillator's light and converts it into voltage pulses
•
The microprocessor receives these voltage pulses after amplification and conditioning by
the photomultiplier tube
•
The microprocessor and associated electronics convert the pulses into a calibratable
output to the Smart Pro electronics
•
The Smart Pro electronics receives and reads the input and converts it into process units
•
Several outputs are available on the Smart Pro, including a 4–20mA output of the
process variable. Refer to the Smart Pro Reference manual for more information.
