ART8100系列本安防爆,帶反饋帶HART
A: If 1 represents die cast aluminum ADC12 material, if 2 represents stainless steel 316L material.
B: If it is L, it represents a straight stroke mode of action; When R, it represents the angular stroke mode of action.
C: If it is S, it represents a single acting action mode; When it is D, it represents a double acting action mode.
D: If it is 0, there is no communication or feedback; When it is 1, it represents a 4-20mA feedback output; If it is 2, it represents hart communication; At 3 o'clock, the meter has 4-20mA feedback output and hart communication.
E: If it is B, it means that the position state of the valve remains unchanged during the fault (fault lockout FL); When it is A, it represents that the valve returns to its initial position during the fault (fault safety FC/FO).
F: If it is 1, it means there is no pressure gauge group; When it is 2, it represents a group with pressure gauges.
G: If it is G, it represents explosion-proof type, explosion-proof level: Ex db IIC T6 Gb; If it is D, it represents dust explosion-proof type, explosion-proof level: Ex tb IIIC T85?℃?Db; When it is GD, it represents the explosion-proof+dust explosion-proof type, with an explosion-proof rating of Ex db IIC T6 Gb/Ex tb IIIC T85?℃?Db.
H: If it is Y, it represents an integrated installation method; When it is F, it represents a split installation method.
J; If it is N, the electrical thread NPT1/2, the gas source NPT1/4; if it is M, the electrical thread M20 * 1.5, the gas source RC1/4; if it is G, the electrical thread G1/2, the gas source G1/4.
K: Number for major clients, consisting of 1-3 letters, customized and defined by the user. The company is responsible for external interpretation and does not involve changes in product safety performance. This tag can be defaulted.
