The upper end cap is fitted with a protection cage. A yoke is fitted at the end of this
protection cage. The transducer is fitted directly on the device's upper end cap. The
ceramic piezoelectric sensor is covered by a neoprene boot. The integral transducer
(Transmitter and Receiver), oil-filled under equal pressure, features:
•
A metallic reflector
•
A CE-000192 ceramic ring
•
A neoprene boot
The integral transducer end cap is swapped for an upper end cap fitted with a 4-way
SUBCONN bulkhead connector for the RT8x1/HD transponders. The associated split
head is referenced PET661S or PET661S-ISOL (with galvanic isolated configuration).
