Hylecs' Pulsar is a compact, hand-held, light weight, coupling-free instrument for measuring the of ultrasonic pulse velocity (UPV) of longitudinal stress waves propagating within concrete.
Pulsar (A1410) is a compact, hand-held, coupling-free instrument for measuring the speed of a pulse of ultrasonic longitudinal stress waves propagating within concrete; that is, it measures the ultrasonic pulse velocity (UPV). The instrument incorporates two antenna arrays, each one with a set of 7 dry-point-contact (DPC) transducers that are brought into contact with the surface of the test object. The receiving antenna is fixed to the electronic unit while the transmitting antenna is connected by a 3 meter cable. Pulsar can be used for the following applications:
- Assessment of concrete uniformity
- Locating internal voids and cracks
- Estimation of the extent and severity of deterioration
- Estimating depth of fire damaged concrete
- Evaluation of damage to test specimens during durability testing (freeze and thaw, sulfate attack, alkali-silica reaction)
- Estimation of depth of surface-opening cracks
- Estimation of early-age strength (with project/mixture specific correlation)
- Evaluation of condition or elastic properties of solid materials like rocks, bricks or composites.
