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 our approved galvanically isolated amplifier. Positek offers Intrinsically
Safe
sensors for the following three hazard classifications:
Positek sensors are now available in the EX02
versions which are
ATEX Qualified
to Intrinsic Safety Specification:
- Ex II 1G, EEx ia IIC T4 (Ta = -40°C to +80°C)
-
Ex II 1GD, EEx ia IIC T4, Ex iaD 20 T135°C (Ta = -40°C to +80°C)
-
Ex I/II M1/1GD, EEx ia I/IIC T4, Ex iaD 20 T135°C (Ta = -40°C to +80°C)
- Certificate number Sira 00ATEX2076X and ATEX SIRA M064
- The ambient temperature rating for T4 is extended 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 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:
