Measurement acoustic sensor D9215

The D9215 is a high temperature, radiation resistant differential AE sensor, specially designed for the nuclear power industry. The differential inputs give the sensors a capability to operate even in extremely noisy environments, the differential signals eliminate the common mode noise at the preamplifier improving the signal to noise ratio to the tune of 2 dB or higher. The sensor features a rugged cavity made from Inconnel 600 and an integral 2 ft long "hard-line" cable. The hardline cable is crimped to a softline twinaxial cable made from Tefzel interfaces the sensor to instrumentation. The sensor is tightly sealed by welding for use in harsh nuclear environment. The sensor has a 100 kHz resonance frequency and 80 kHz to 560 kHz bandwidth. All the materials used in this sensor have been proven for use in nuclear environments. The Maximum operating temperature of the sensor is 540°C and the softline cable can be operated at a maximum temperature of 150°C.
