N = No Approvals
E = Explosion Proof
S = ATEX/Intrinsically Safe
The SPX series of pressure transmitters are designed for explosion proof areas
approved by Factory Mutual and CSA for Class I, Division 1, Groups A, B, C & D.
The SPX series of pressure transmitters is specially designed for measuring pressure in
explosive atmospheres for Zone 0 under safety class II 1 G EEx ia IIC T4 (TA = -20 to + 60°C).
The SPX is also approved for hazardous area Zone 1 under safety class
II 2 G EEx ia IIC T4/T6 (T4, TA = -20 to + 85°C; T6, TA = -20 to + 50°C)
For category 1 (Zone 0) installations, care must be taken to avoid the danger of ignition due to
electrostatic discharges (ESD). The chance for static build up on the cable surface during normal
conditions of use, maintenance and cleaning must be eliminated. Install the cable in an appropriate
conduit or use some other cable reliable installation technique to avoid static electricity at the cable
surface. The free length of the cable shall be below 5 cm. If metallic conduits are used they need to be
grounded. If nonmetallic conduits are used they need to be antistatic (< 1G Ohm/cm
2
).
