EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
The T-Series TH is a magnetostrictive linear position sensor comprising a stainless steel hexagonal cross-sectional enclosure and
cylindrical measuring element.
The enclosure comprises two compartments; one containing the electronics and the other containing termination facilities for the
connection to external circuits. The compartments are separated by a spigoted bushing with the terminal compartment cover being
secured by five M4 socket-head cap screws grade A4-50. The rear of the electronics contains a threaded boss through which passes
the measuring element.
Cable entry is made via either an M16 threaded boss to the side of the terminal compartment, which may optionally be fitted with an
M20 or ½" NPT thread adapter, or an M20 entry in the cover.
A facility for an external earthing or equi-potential bonding conductor is provided on both the terminal and electronics compartment
comprising: a ground block; an M4 Screw; an M5 screw; a spring washer; a clamping tab.
Conditions of manufacture:
1 When the position sensor Temposonics
dielectric strength test in accordance with IEC 60079-7 clause 6.1.
CONDITIONS OF CERTIFICATION: YES as shown below:
1 For repair of the flameproof joints, contact the manufacturer for information on their dimensions. Repairs must not be made on the
basis of the values specified in Tables 1 and 2 of IEC 60079-1.
When installing the p osition sensor Temposonics
2
requirements of IEC 60079-26 and IEC 60079-10-1 must be complied with. At this, the interface must be sufficiently tight (IP66 or
IP67) or form a flameproof joint according to IEC 60079-1 (joints specified for a volume ≤ 100 cm
hazardous area. In addition, the p osition sensor Temposonics
upstream fuse of 125 mA.
3 The sensor tube must be protected from mechanical damage.
