ATEX Sensor Solutions for Explosive Situations

Rechner Sensors produced their first certified sensor for an explosion potential application back in 1974 making them one of the oldest and most experienced producers of these application critical sensors. With so much experience and expertise, you can rely on Rechner ATEX sensors for applications in explosive environments. Ideal for any sensor installation in DUST or GAS explosion zoned applications, including certified sensors for the defined zone in a broad range of sizes and formats. Rechner also manufactures cable connections and approved ATEX interface amplifiers for interconnection to the system control.

ATEX Applications

In some cases non-ATEX applications can become re-zoned as ATEX and all of the installed sensors must be replaced with suitable certified product. Rechner’s All-In-One ATEX Sensor Range is the perfect choice as it can be interfaced to the existing control but also has ATEX certification for detection in the ATEX rated zones for DUST Zone 20 and GAS Zone 1. These sensors do not require expensive interface barriers to connect them to a control system in ATEX applications.

ATEX rated sensors achieve protection by encapsulation including a non-replaceable fuse. Rechner’s ATEX certified Sensors come in capacitive as well as inductive formats for direct PNP or NPN system connection. Inductive sensors are available in M12, M18 and M30 Flush configurations.

Rechner’s Capacitive ATEX Sensors have a wide portfolio of shapes and sizes from the compact M18, G1/2” up to G1”, M32, including Tri-Clamp options, for both Flush and Non-Flush sensors. Cable and connector versions of each sensor type are available and Clips to prevent disconnection while powered are supplied with each pluggable sensor.
