flameproof type Ex d, suitable for the conditions of use and
correctly installed.
2. Unused apertures shall be closed with suitable blanking
elements.
3. When the ambient temperature at the cable or conduit entries
exceed 60 °C, cables suitable for at least 90 °C shall be used.
4. Remote mounted sensor; in type of protection Ex ia IIC, only to
be connected to the associated Model 8800D Vortex Flowmeter
electronics. The maximum allowable length of the
interconnecting cable is 152 m (500 ft).
Special conditions for safe use (X):
1. For information regarding the dimensions of the flameproof
joints, the manufacturer shall be contacted.
