Housing Material & Stud Size(1) 01 303 SS housing, ½” NPT stud
Hazardous Area Certification(3),(4),(5),(6) 3 ATEX, Ex ia IIC T4 Ga (intrinsically safe)

High-Pass Filter 0 2 Hz (standard)
Low-Pass Filter 0 1500 Hz (standard)
Smaller-diameter mounting studs are not able to withstand sustained ambient vibration levels above 2.0 in/sec. Consult Table 2 for allowable combinations of A and B options.
The ST5484E uses an RMS amplitude detection circuit. Full scale ranges in peak units use scaled RMS (i.e., RMS x v2). The “derived peak” measurements will equal true peak only under the special case of a pure sinusoid, not complex vibration signals.
Hazardous Area Certifications are not compatible with all connection types. Consult Table 3 for allowable combinations of C & D options.
Some approvals require intrinsic safety barriers, others require Explosion-Proof wiring practices. Refer to Table 4.
Refer to the Accessories section of this document. Units sold with an explosion proof or increased safety rating will include an 8200- 000 IEC or 8200-000 explosion proof elbow that will be affixed at the factory. For increased safety with D=4, elbow is not required.
For SIL approval, add an “S” prefix to the desired Hazardous Area Certification (Option C).
