Fluid Pressure Transducers (FPTs) are used in large quantities in and around all types of rolling mills. For most of these applications any inexpensive FPT with built-in electronics will do.
However, the FPTs used to track changes in hydraulic cylinder pressure in hydraulically actuated mill stands are critical: If any of these fail, the entire rolling operation must stop, and remain stopped until the FPT is replaced and the spilled hydraulic fluid - sometimes very flammable - is cleaned up. Unfortunately catastrophic failure of ordinary FPTs is quite common, as they typically feature a flimsy construction and are weakened whenever they are opened in order to adjust their internal electronics.
KELK Fluid Pressure Transducers are the most rugged FPTs available anywhere, so strong that they carry the KELK 5 year Rollmax guarantee. And KELK FPTs use the same external electronic systems as KELK Load Cells and Tensiometers. That means they never have to be opened once in service, and users can stock common spares.
