ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the
petrochemical - 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.
Applicable for concrete inspection allowing imaging of the internal
structure of objects from
concrete, reinforced concrete, different
stones. The operation applies pulse-echo technique at one-side access
to the object. The instrument is feasible for concrete inspection for
searching conduct ducts, conduits, detection of foreign inclusions,
holes, honeycombing, cracks and other concrete defects. [more]
The Exertus Dual 120 Projector has the ability to accept Iridium 192
sources or Selenium 75
sources. This projector incorporates design
safety features that make it flexible, compact and lightweight.
The Projector is lighter than most of its competitors. It
incorporates an improved source channel, based on a new helicoidal
design, which makes maintenance easier. The helicoidal design also
allows smoother movement of the source assembly inside the device,
making it easier for the operator and improving safety. The
Projector also has a unique safety feature not found in competitive
The source assembly locking mechanism is triggered by the source
holder capsule at the front of the source assembly, thereby always
assuring the operator that the source has returned to the
safe position. The Exertus Dual 120 is ISO3999:2004 compliant. [more]
