ATEX approval
|
The
sensor is ATEX approved to II 1G EEx ia IIC T4 (Ta = -40°C
to +80°C). This designates the sensor as belonging
to; Group II: suitable for all areas except
mining,
Category 1 G: can be used in areas with continuous, long or
frequent periods of exposure to hazardous gas (Zone 0).
Protection
class ia, denotes intrinsically safe for all zones.
Apparatus group IIC: suitable for IIA to IIC explosive gas.
Temperature class T4: maximum sensor surface temperature under
fault conditions 135°C. Ambient temperature range
extended to -40°C to 80°C.

Galvanic Barrier
|
Intrinsically
safe sensors must be used with a galvanically isolated barrier
with safety parameters not exceeding:- Ui: 11.4V, Ii: 0.46A,
Pi: 0.51W. Sensor can be installed with a cable length
up to 150m maximum from the barrier, capacitance and inductance
can be up to:- Capacitance: 550 nF max, Inductance: 99 μH
max.
Approved
barriers are available from Positek; there is a
choice
of 0.5-9.5V or 4-20mA transmission
outputs. The sensor is calibrated to suit the selected barrier
transmission output.
