Description
EXPLOSION-PROOF ELECTRICAL CONTACTS
Inductive typeï¼ECI series
APPLICATIONS
The electrical contacts are fitted into the case of pressure gauges
and intended to make or break an electric control circuit to the
position of the pointer on the instruments.
DISCRIPTIONS
The pressure gauge with explosion-proof inductive is inductive
approach form, because of non-contact-type, it has no any spoilage
to the power supply system. Without electric spark, long using
life, little impact on the measurement accuracy, it is not only
applicable to certain dangerous places, but also suitable for
frequent turn on/off occasions.
ECI series explosion-proof inductive pressure gauge is based on
GB***6.1 (the request of the electric equipment used in explosive
gas environment) and GB***6.4 (safe explosive gas environment
electrical equipment intrinsically safety-type 1).
