* 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.* DESCRIPTIONS: 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 GB3836. 1 (the request of the electric equipment used in explosive gas environment) and GB3836. 4 (safe explosive gas environment electrical equipment intrinsically safety-type 1).
