Cygnus 1 Ex

The Cygnus 1 Ex Ultrasonic Thickness Gauge is a rugged, handheld, battery-
powered, intrinsically safe instrument designed for taking reliable thickness
measurements using ultrasound in Zone 0 (Class 1 Division 1) Explosive
Atmospheres. It features a large colour LCD display which can be viewed in most
light situations including sunlight. A rechargeable battery pack provides 8 hours of
use.
The instrument can be used with a choice of Ex Ultrasonic Probes, which can be
selected to suit the material and thickness range to be measured.
The Cygnus 1 Ex can measure material thickness using the following measurement
modes,
• Single Echo - UT Mode 2
• Echo-to-Echo - UT Mode 3
• Multiple Echo - UT Mode 3
Through-coating measurements are possible using Echo-to-Echo and Multiple Echo
modes.
The instrument can easily be calibrated to a known thickness or to a known
Velocity of Sound.
The instrument is able to operate accurately over a wide range of ambient
temperatures and is environmentally sealed to IP67 for use in wet conditions.
The Cygnus 1 Ex is a solid-state electronic instrument which, under normal
operating conditions, will give many years of active service.
Although designed for ease of operation the first-time user should carefully
read this manual to familiarise themselves with the features of the Gauge.
