Linear and angular measurement system for applications in hazardous areas (ATEX)

SIKO GmbH: In some areas of application, such as the oil and gas industry and also in many areas of the chemical industry it is necessary to use sensors that are ATEX-certified (ATmosphères Explosibles). The ATEX certification is used in the area of explosion protection. 

New sensor for applications in potentially explosive areas

Designed by SIKO GmbH for use under ATEX conditions, the magnetic sensor MSK320SKF came about in the course of a new product development. The sensor is therefore suitable for use in potentially explosive areas and opens up new applications in the field of explosion protection.

To ensure safe use, the MSK320SKF-type sensor must be used with a defined protective barrier. The sensor can be used in Zone 1 and 2 (high and normal safety).

An all-round dedicated player

The sensor’s “resilience” makes it extremely versatile. In continuous use, SIKO sensor technology has proven its cost-effectiveness; since the MSK320SKF is extremely durable and virtually “indestructible”. Follow-up costs for maintenance and replacement are now a thing of the past.

The MSK320SKF sensor operates as an open system, linear or rotary, wear-free and low-maintenance. A large selection of corresponding MB320/1-type magnetic bands and MR320 / MBR320-type magnetic rings are available in order to adapt to various shaft diameters.

The variety of available magnetic rings of varying diameters and pole numbers means flexibility and allows its use in many machine designs.

Self-testing made easy

Apart from comprehensive expert advice, SIKO now also offers the opportunity of testing a sample device of the new sensor.
