1.  Better than 1% set-point repeatability
   Users can expect a set-point repeatability performance better than 1% on all configurations with some configurations being significantly better
2.  Extensive range of approvals
   The Industrial Series switches are available with wide range of different approvals including European and North American Hazardous Area approvals
3.  Safety
   All Industrial Series models come with a safety vent to prevent the enclosure becoming pressurized in the event that the sensor is inadvertently damaged by excessive pressure. In addition, all models have been certified for use in safety systems up to and including SIL 2.

The Industrial Series switches were developed in the mid-1990's to offer customers a robust range of switches suitable for applications where requirements were more standard than those for which the highly configurable Performance Series switches were designed.

Using diaphragm based sensors and a more traditional in-line force balance mechanism to transfer movement from the sensor to the microswitch, these switches are suitable for a wide range of industrial applications. Various international approvals make the Industrial Series suitable for use in both safe and Hazardous Areas in Europe, North America and throughout the world.

With the recent launch of the Sentry Series, these Industrial models are now recommended mainly for aftermarket applications where a like for like replacement is needed.
