This rubber protector is designed to protect gauges which are bonded onto metal surface from the environment for long-term measurement. The strain gauge is packed inside together with the applied adhesive and overcating materials. The protector is also provided with a hole for cable intake. It allows the entire area to be isolated from ambient conditions which may affect reliable measurement, and further increases the coating performance.
Strain gauges with a large-size backing, such as the PFL-30-11 ane PL-60-11, cannot be used with the Gauge Protector.
