DAMPENING MATERIAL
- An high density dampening material, such as Dacron or other synthetic fibers, is required for better performance;
- Please refer to the drawing as a guide

PRESSURE SENSOR POSITIONING
- As show in the example the sensor should be fixed in the 10mm diameter hole with a neoprene (or other expanded rubber) gasket to avoid air-leakage;
- Be careful when fixing the sensor, an excessive screwing could damage the housing;
- Sensor’s hole position is specified in the Front chamber panel drawing;
