SICK introduces plug-and-play pressure switch

SICK has added a new pressure switch to its range of industrial instrumentation products.

The PBS pressure switch combines the functionality of a pressure transducer, a pressure switch and a display in a single package.

Darren Pratt, UK instrumentation product specialist at SICK, said: 'The PBS pressure switch is very easy to install, making it a plug-and-play solution.

'It also has the advanced functionality to integrate with modern plant supervisory control and data acquisition and network communications.

'The new PBS is exceptionally adaptable and lends itself to virtually any plant configuration, without compromising on cable position, visibility or leak integrity, making it ideal for a retrofit as well as a new plant.

'Suitable for general, non-hygienic applications, it complements our new PHT hygienic pressure sensor, introduced in 2009,' he added.

The PBS is suitable for absolute, gauge and vacuum/compound pressure application requirements, with a choice of pressure ranges from 0-1bar up to 0-600bar.

Its construction includes a hermetically sealed welded stainless-steel membrane over the sensing element, eliminating the requirement for leakage-prone internal seals.

The PBS can be configured using three pushbuttons and an integral light-emitting-diode display or remotely from higher-level fieldbus networks via IO link, available with some models.

Configuration does not require extensive menu searching.

The two digital switch NPN or PNP outputs are configurable for monitoring over or under pressure and 0-10V or 4-20mA analogue pressure monitoring is also available.

The PBS housing and display have been specifically designed to be rotated and orientated up to 330 degrees to facilitate reading and configuration in virtually any plant situation.

This allows installation without disturbing the cable loom and reduces errors in reading the display or when entering instructions, according to the company.

SICK's PBS features a choice of process connections, eliminating the need for costly adaptors with potential leakage points.

Electrical connection is via an industry-standard M12 four- or five-pin stainless-steel connector, providing sealing to IP67.

The PBS pressure switch is part of the company's range of industrial instrumentation solutions, including level, pressure, flow and temperature sensing.
