LP2 probe system: LP2 basics
LP2 probe types
There are four versions of the LP2 probe. Each version is best suited to particular applications:
• LP2 – For normal setting/inspection. The metal eyelid protects the diaphragm in a hot chip and
coolant environment.
• LP2H – With higher stylus pressure for long or heavy styli, or where there is excessive machine
vibration.
• LP2DD – LP2HDD – The double diaphragm (DD) arrangement is recommended for grinding
machines and other applications with particle-laden coolant. The LP2HDD is a version with a higher
stylus spring pressure, similar to the LP2H.
NOTE: LP2DD probes are available as original equipment, or existing LP2 probes may be converted
to the DD standard using a conversion kit.
