Intrinsically Safe systems provide a safe operating environment for personnel and
equipment. Intrinsic Safety (IS) is based on the principle of restricting the
electrical energy transmitted into a hazardous area, thereby ensuring that any
sparks or heated surfaces that may occur as a result of electrical failures are
insufficient to cause ignition. The threat of an explosion is eliminated.

Positek's ATEX and IECEx approved Intrinsically Safe sensors can be used in hazardous environments when
connected to our approved galvanically isolated amplifier. Positek offers
Intrinsically Safe sensors for the following three hazard classifications:

'X' Series Sensors	Position Sensors for use in potentially explosive gas/vapour atmospheres.
'E' Series Sensors	Position Sensors for use in potentially explosive gas/vapour and dust atmospheres.
'M' Series Sensors	Position Sensors for use in potentially explosive gas/vapour, dust and mining environments

Positek sensors are now available in the EX07 versions which are ATEX and IECEx
Qualified to Intrinsic Safety Specification:

• II 1 GD
  I M1
  Ex ia IIC T4 Ga
  Ex ia IIIC T135°C Da
  Ex ia I Ma
  Ta = -40°C to +80°C

• Certificate number Sira 13ATEX2371X and IECEx SIR 13.0154X
• The ambient temperature rating is extended to -40°C to +80°C.
• Approval only applies to the certified code, specified ambient temperature range and atmospheric conditions in the range 0.80 to 1.10 Bar, oxygen <21%.

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 buffered
output to a safe area.

The Positek X005 Galvanic Isolation Amplifier designed specifically for use with Positek Intrinsically safe sensor range is available in the following output options:

0.5 to 9.5V	-	X005-545
9.5 to 0.5V	-	X005-546
4 to 20mA	-	X005-425
20 to 4mA	-	X005-426
