Pumped for military and aerospace applications, the AST2000 and AST20HA pressure transmitters enlist Krystal Bond technology, which entails a one-piece stainless steel sensing element that’s free of welds, oil-filled cavities, and internal O-rings. Operating in temperatures from -55°C to +75°C, their one piece sensing element will not experience O-ring failures or frozen/boiling fluid filled cavities. Both components are digitally compensated, ensuring accuracy across the entire operating temperature range. Additionally, the AST2000 and AST20HA can handle shock, vibration, and wash-down to military standards such as MIL-810 and MIL-461. AMERICAN SENSOR TECHNOLOGIES INC., Mount Olive, NJ. (973) 448-1901.
