QAWRUMS WI500 Wideband AE Sensor, >65dB, 500kHz, Built-In Preamplifier (28V), SMA Connector

The integrated 40dB preamplifier requires a 28V DC power supply, which is typically provided through the same coaxial cable used for signal output via a constant current line powering scheme common in AE systems. Ensure your data acquisition system or preamplifier power supply is compatible with this voltage.

The SMA connector provides a robust, low-noise RF connection for the sensor's output signal. You should use a high-quality, shielded coaxial cable with SMA connectors to maintain signal integrity and minimize electromagnetic interference over the distance to your data acquisition unit.

The sensor features a flat ceramic face for optimal acoustic coupling. It should be mounted using a suitable acoustic couplant (grease or adhesive) and can be secured with magnetic hold-downs, clamps, or adhesive bonds, depending on the application and surface requirements, ensuring firm and consistent contact.

With its SUS-304 stainless steel housing and IP62 rating, the WI500 is protected against dust and light water splashes, making it suitable for many industrial environments. However, for prolonged submersion or highly corrosive conditions, additional protective measures or a higher IP-rated housing may be necessary.
