PBS Hygienic pressure switch by SICK

From:Food Magazine

PBS Hygienic is the new electronic pressure switch designed by SICK specifically for measuring and monitoring pressure in the food industry. The selection of material, the structural layout, as well as the process connections were laid out consistently in hygienic design.

Pressure switches are used for detecting process pressures. If the applied pressure reaches the preset switching threshold, the transistor output changes its output state. In addition, the PBS Hygienic provides an output signal proportional to the applied pressure (current 4…20 mA or voltage 0…10 V) geared to further evaluation by the plant control, e. g. for control processes.

Consistently hygienic
The wetted parts of the PBS Hygienic are made of high-quality 1.4435 stainless steel. The extremely durable and temperature resistant stainless steel membrane is welded to the process connection in hygienic design without gaps or edges, minimizing the hygienic risk to the operator. The smooth surfaces are gap-free and have no dead spaces, which allows cleaning and sterilizing the PBS Hygienic without residues even when installed, e. g. in CIP and SIP processes. Thus, one can achieve optimized plant availability.

High level of integration and operating convenience
The housing of the PBS Hygienic can be rotated in two ways. This means that the display and electrical connection can be aligned to match the specific installation situation in the best possible way. Intuitive setup by means of three large pushbuttons and the generously sized display for pressure values and output states provide for reliable and easy setting of the pressure switch. This pressure switch comes with up to two independent switching outputs, analog output and IO-Link in one device. In case of a product changeover, one can use the automation system via IO-Link to adjust all relevant parameter settings quickly and reliably during ongoing operations. This contributes to improved plant availability and thus to increased productivity.

Configurable without compromise
The PBS Hygienic is an innovative electronic pressure switch suitable for gauge, vacuum and absolute pressure measurement within the following ranges: –1 – 0 bar to 0 – 25 bar. This feature and the hygienic process connections enable individual configuration depending on the respective application and installation situation, thus providing a maximum degree of flexibility with respect to pressure and level measurement in hygienic design.
