Guard

A protective guard is sometimes a necessary accessory to protect the operator in the event of sample fragments leaving the test area during a test. 

A guard is available for operator protection from such fragments or violent failures of specimens such as hard and brittle materials that may shatter or create projectiles upon failure. In addition, there are instruments used by multiple and/or unskilled operators that may prefer the installation of such a guard for an extra degree of operator safety. 

The guard is constructed of a strong yet lightweight acrylic panel which allows clear observation during a test whilst minimising weight. A handle at the front of the instrument provides the means to lift the guard. An interlock mechanism requires that the guard is at its lowest 'closed' position prior to starting a test and will interrupt the test in the event that the guard is lifted up during a test. Upon lifting, any test that is underway will immediately stop and an audible signal will be produced. The guard has dampers which enable the panel to remain at any lifted position without dropping down. 

The design is such that the guard works within the existing footprint of the Texture Analyser with no additional bench space required.
