“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 retrofit, as well as new plant. Suitable for general, non-hygienic applications, it complements our new PHT hygienic pressure sensor, introduced in 2009.”
The new PBS is suitable for absolute, gauge and vacuum/compound pressure application requirements, with a wide choice of pressure ranges from 0 to 1 up to 0 to 600 bar. The robust 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 easily configured using three push-buttons and an integral LED display, or remotely from higher level fieldbus networks via IO link, available with some models. Configuration is rapid and intuitive, and doesn’t 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˚ to ensure easy 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.
SICK’s PBS boasts a wide choice of process connections eliminating the need for costly adaptors, with potential leakage points. Electrical connection is via an industry standard M12, 4 or 5 pin stainless steel connector, providing sealing to IP67.
The PBS pressure switch is part of SICK’s growing range of Industrial instrumentation solutions including level, pressure, flow and temperature sensing.
Pratt concluded: “Our aim is to provide innovative instruments which reflect the quality and value associated with the SICK brand. The new PBS meets these high expectations providing customers with the reliability and ease of use necessary in a modern, lean production environment.”
