AST4000 pressure sensor features special configurations so it can be modified to withstand a variety of mechanical, electrical, and environmental challenges in hydraulic pressure measurement applications. It is available with 1/4 in. NPT male, 7/16-20 UNF (SAE4), and 9/16-18 UNF (SAE 6) pressure ports. It is rated for burst pressure to 20,000 psi. Standard proof pressure is two times the rated pressure, but it can be specified with a 4x proof pressure.American Sensor Technologies Inc., (973) 448-1901, www.astsensors.com
