Explosion-proof construction:
Explosion-proof construction is a totally-enclosed
construction such that even if an explosive gas explodes
inside the container, the container will withstand the force
of the explosion and there is no danger of ignition by
external explosive gases. Our pressure and differential
pressure transmitter manufactured under this policy are
used in pressure measurements where inflammable gas or
the inflammable gas vapors may exist in factories and
business offices.
Explosion-proof type approval:
Conforms to Ministry of Health, Labour and Welfare
Notification structural standard and new engineering
standard and new explosion-proof policy adjusted by IEC
international standard.
