Wedge delay is the time that sound travels in the wedge only, total beam delay is the duration of time from when pulse is generated to the time that pulse enters the specimen, to make it simpler, USUALLY total beam delay is wedge delay + couplant delay if you are performing contact testing.

beam delay(time delay) is an electronic delay of the pulse energy in other to achieve a particular beam formation pattern while wedge delay is simply the determination of the distance or time of travel in the wedge in other to accurately determine the beam exit point from the surface of the wedge(this help for proper location of flaws).

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.
