供應(yīng)DP15I 美國物理聲學(xué)公司PAC聲發(fā)射傳感器

DESCRIPTION AND FEATURES:The DP15I sensor is a medium frequency, resonant, acoustic emission sensorwith an integral 40dB preamplifier, which can drive up to 1000ft of cable. The DP15Ifeatures a strong insulated, lightweight, Aluminum alloy, integrated bodystructure. The sensor outside shell isanodized, providing a non-conductive finish, to prevent any possible electricshorts from metal testing structures. The DP15I has excellent EMI noiseimmunity. It also has built-in AutoSensor Test (AST) capability, suitable for use with all PAC systems. The DP15Isensor is thesamesize as the industry standard R15I sensor and has a similar frequency responseand sensitivity.
