Pressure transducer MEAS MS4525

vacuum pressureanalog

Product summary
The MS4525 is a compact ceramic-based PCB-mounted analog pressure transducer. Fully calibrated and temperature compensated (total error band <1.0% over the compensated range). Operates from a single 3.3 V or 5.0 V supply and requires a single external component. Available in side-port, top-port and manifold-mount variants. Measures absolute, gauge, differential or compound pressure from 1 to 150 psi. 1/8 in barbed pressure ports mate with 3/32 in ID tubing.
