ifm efector offers a new line of non-contact intrinsically safe position sensors and switching amplifiers for hazardous area applications. These intrinsically safe devices can be installed in hazardous area environments that contain atmospheres with ignitable gas-air mixtures, dusts and fibers without causing fires or explosions. Typical applications are found in chemical plants, grain silos, food additive/powder mixing areas, and automotive paint stations.
Intrinsically Safe Sensing System
Together, the position sensor and switching amplifier form an intrinsically safe sensing system. The amplifier limits electrical and thermal energy to prevent ignition, potential arcing or sparking between the sensor and combustible material. FM, CSA and ATEX approved ifm’s intrinsically safe sensors, which include inductive, capacitive and valve position sensors, are FM, CSA and ATEX approved for Division 1 hazardous areas when used with an ifm switching amplifier. During installation, special devices such as conduit or metal-clad cables are not required, and ifm’s intrinsically safe equipment can be maintained without plant shutdown.
