Positek sensors are now
available in the EX06 versions which are CSA approved
Class I, Zone 0
Ex ia IIC T4 (Ta = -40°C to +80°C)
AEx ia IIC T4 (Ta = -40°C to +80°C)
AEx iaD IIIC T93°C(Ta = -40°C to +80°C)
Designates the sensor as belonging to; Class I, Zone 0:
suitable for all areas except mining, : can be used in areas
with continuous, long or frequent periods of exposure to
hazardous gas / vapours.
Protection class ia IIC, denotes intrinsically safe for Zones
0, 1 & 2 and IIA, IIB and IIC explosive gases.
Temperature class T4: maximum sensor surface
temperature under fault conditions 135°C.
Ambient temperature range extended to -40°C to +80°C.
The sensors must be used with a galvanically isolated
three port amplifier
designed to supply the sensor with a nominal 5V and to transmit the
output to a safe area.
