201/202/203/281 Pressure Switch

Key Features

Better than 0.5% set-point repeatability

Users can expect a set-point repeatability performance better than 0.5% on all configurations with some configurations being significantly better

Extensive range of options

The Performance Series switches are available with an extensive range of materials, process connections, switch types, electrical entries, etc and offer customers many millions of different possible configurations.

More than 35 years experience in the field

Installed in a wide range of applications from nuclear power plants to offshore oil rigs, the Performance Series’ long experience in the field offers customers the reassurance that they can be relied upon to survive the test of time in the harshest environments.

Safety

All Performance 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.
Designed in the mid-1970s and developed over subsequent years, the Performance Series switch range offers users the broadest range of options, the highest levels of set-point repeatability and the confidence of long term performance that a mature product such as this can prove.
The Performance Series switches utilise bellows or bourdon tube type sensors that offer a very linear response to pressure change. These sensors, coupled with a precision stainless steel mechanism designed to minimise friction in the moving parts, helps deliver the market leading performance customers have come to expect from the series.
