CYYZ91EY Compact Pressure TransmitterRange 0~4~40MPa Output 4~20mA Power supply 9~28VDC Accuracy 0.5%FS
CYYZ91EY compact pressure transmitter is designed for measuring adhesion, crystallization, mixed contamination, etc. The flat membrane design is adopted to effectively prevent the blockage of the impulse hole. The process connection adopts the radial sealing method of the lower end of the thread, so that the measuring medium is effectively isolated from the connection thread, and the adhesion and mixed contamination of the threaded connection are avoided. Compact structure and small size, suitable for industrial equipment with limited installation space, etc., the internal sealing treatment makes it have the advantages of anti-vibration and anti-condensation.
