ATEX-Approved Intrinsically Safe Sensors

 

 
For applications in hazardous locations, 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 Intrinsically Safe sensors can be used in hazardous environments when connected to a the approve safety barriers. Positek offers Intrinsically Safe sensors for the following three hazard classifications:

X Series Intrinsically Safe Sensors
'X' Series Position Sensors for use in potentially explosive gas/vapor atmospheres.
Ex II 1G, EEx ia IIC T4 Ga(Ta = -40°C to +80°C)

E Series Intrinsically Safe Sensors
'E' Series Position Sensors for use in potentially explosive gas/vapor and dust atmospheres.
Ex II 1GD, EEx ia IIC T4 Ga, Ex iaD 20 T135°C (Ta = -40°C to +80°C)

Intrinsically Safe Sensor Barriers

The X005 Galvanic Isolation Amplifier has been designed specifically for use with Positek® X Series, E Series, and M Series Intrinsically Safe position sensors. The G005 provides a regulated and resistively limited +5V dc power supply required by Positek® IS sensors, and it can be connected in three or five wire modes. The G005 has an input power supply range of 12 to 30 volts dc, making it suitable for a wide range of hazardous area applications. The output of the G005 is factory configured to either 0.5 to 9.5V or 4-20mA and has a bandwidth of 4.7kHz, making it ideal for servo control loops.
