Remote mounted sensor: in type of protection Ex ia IIC, only to be
connected to the associated Model 8600D Vortex Flowmeter
electronics. The maximum 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.
2. The Flowmeter is provided with special fasteners of
property class A2-70 or A4-70.
3. Units marked with “Warning: Electrostatic Charging
Hazard” may use non- conductive paint thicker than 0.2
mm. Precautions shall be taken to avoid ignition due to
electrostatic charge of the enclosure.
4. When the equipment is installed, precautions shall be
taken to ensure the ambient temperature of the
transmitter lies between –50 °C to +70 °C, taking into
account process fluid effects. If the ambient temperature is
outside this range remote transmitters shall be used.
