This advanced, patented design ensures the sensor remains sealed, locked and pre-loaded to the opposite wall regardless of changes in pipe diameter due to pressure, temperature or mechanical force. This design has important advantages:

• Fugitive emission and leak prevention…The Spring-Lock continually compensates for the differential in packing and body growth rates due to increased temperature

• Increases sensor strength, thereby eliminating the need for an opposite wall support. A locked, pre-loaded sensor is four times stronger than a non-pre-loaded, cantilevered sensor

• Other mounting methods do not pre-load the sensor or the packing seal and are subject to increased sensor vibration, metal fatigue, breakage
