A Problem in "KB's USM 3S"

Back Ground.
~~~~~~~~

In the High Voltage/Tension Card Sp 30085 - 3.220
a transformer is used to creates the high voltage for CRT of Upto 13 kV (Tr.1 30091 - 5.950).

From our experience from 9 out of 10 failures in that High Voltage/Tension Card in USM 3S, it is the transformer that fails.

Suggestion Needed:
~~~~~~~~~~~~~

I am sure that so many of this reputed forum are still using KB's USM 3S's for Ultrasonic NDE, and there will definitely be someone, who came across the same problem, i.e. the failure of the transformer (Tr.1 30091 - 5.950) on the High Voltage/Tension Card.

I hereby, request the representatives in this forum for a solution (if there is any) of the above mentioned problem.

May be re-designing of the Transformer,
re-designing of the High Power/Tension Card,

Or may be a supplier or a instrumentation company, still repairing those boards.

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
