PT139 | PT139A
Dynisco PT139 and PT139A pressure sensors are designed to measure hydraulic pressure in extreme conditions for testing vehicles, stands and other hydraulic and pneumatic applications. These sensors withstand cyclic pressure and provide excellent performance during demanding industrial conditions.
The compact and robust design is ideal for space-constrained applications. The fully welded steel construction is ideal for demanding industrial applications. Thanks to the sealing, they are environmentally friendly and thus prevent unwanted contamination of the system.
