09:29 Sep-05-1998 Detecting Voids in Voided Post-Tensioned Concrete Decks
This message is reference to Chris Barnes inquiry ================================================= Chris,
I forwarded your message to Dr. Soheil Nazarian of the University of Texas at El Paso for suggestions. Dr. Nazarian suggested to contact the consulting firm named SWK Pavement Engineering. They have great expertise with ultrasonic NDE of bridge decks. They are the subsidiary of a British Co. in New Jersey. The contact is Kaz Tabrizi at 609-430-9888 ( firstname.lastname@example.org ).
The Armor Kit Contains the NOVO Armor, which provides additional mechanical protection to the NOVO
15WN & NOVO 22WN Detectors, the Armor Stand and a traveling soft cover.
- Newest shock absorbent technology case
- Water resistant design
- Supports wired & wireless communication
- Multiple positioning options
- Tripod connection using the Built-in 1/4” threads
- Simple Detector battery replacement [more]
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.
