They have no moving mechanical parts to wear out. Capable of measuring in either bar or psi units, the new sensors are good for monitoring pressure in applications such as hydraulic clamping systems, and vacuum systems for pick-and-place units.
PSI: PSI: Programmable pressure sensors
Turck (Minneapolis, MN) offers a complete new line of fully programmable pressure sensors. Reliable, solid state devices available with a variety of options for most pressure analysis applications, these robust devices operate on the piezoresistive principle.
