YOKOGAWA Y/15FA and Y/13FA Pneumatic Differential Pressure Transmitter
YOKOGAWA Pneumatic Differential Pressure Transmitters Model Y/15A measure differential pressure in spans from 1.25 to 6.2 kPa at static pressure to 3.5 MPa. The instruments transmit a proportional 20 to 100 kPa signal to remote pneumatic receivers.
Ordering Examples:
Y/15A-LS1
Y/15A-LS2
Y/15A-LS3
Y/15A-LS4
