PDV-A
Corrosion Resistance with Built-in Variable Damping Mechanism
PDV-A series pressure transducers have diffusional semiconductor strain gages on a silicon diaphragm. PDV-A transducers detect pressures as resistance variation and then amplify this singal by built-in amplifier.
?? High frequency response
?? Highly accurate
?? High sensitivity
?? Noise resistant
?? Voltage output of 5 V (PDV-A)
?? Compact and lightweight
Note
(1) Use the transducer with general air.
(2) If water or any other liquid enters the low-pressure line the transducer gets out of order.
