AE Sensors: KRN Services

KRN Services

The KRN Services product line includes resonant sensors available with or without integral preamplifiers, models available with impedance-matched pulse-through capability, broadband sensors, specialty sensors, and underwater sensors.
The new broadband sensor has nearly flat response from ~5kHz to nearly 2MHz and underwater sensors are capable of long-term immersion in seawater to 10,000 feet and include wet-connection cables.
The standard integral preamplifier sensor models KRNi60kHz, KRNi150kHz, and KRNi400kHz are repairable at a reduced cost compared with replacing with a new unit. No other AE sensor company offers a repairable sensor.
