Cool solution for steel makers: Pressure switches from SICK in chinese hot-rolling mills

Aug 16, 2013

The Jiangsu Sha Steel Group is the largest private steel group in the Peoples Republic of China. For detection of oil and water pressures PBS pressure switches are being used. The transmitter, pressure switch, and display are accommodated in a single compact sensor housing and due to the harsh operating conditions they meet special requirements.

The annual production capacity of Jiangsu Sha Steel Group is 30.5 million tons of iron, 37.8 million tons of steel, and 36.6 million tons of rolled steel. The steel products manufactured are quite diverse - among others, steel plates, sheet metals, wires, and stainless steel - and feature over 2,000 specifications. In order to manufacture products of the highest quality, the Jiangsu Sha Steel Group relies on automated processes. Sensors used in this context must meet special requirements due to the harsh operating conditions.

Particularly in the hot-rolling mills of the Jiangsu Sha Steel Group, the PBS pressure switch from SICK enjoys high esteem. The transmitter, pressure switch, and display are accommodated in a single compact sensor housing featuring an IP65 or, respectively, IP67 enclosure rating. It is used, among other things, for detection of oil and water pressures. The circularly welded stainless steel membrane makes the PBS very resistant against numerous aggressive media. The user-friendliness of the PBS receives particular praise: For optimum installation, the electrical connector and the sensor head with the blue 14-segment display can be rotated and aligned depending on the respective installation situation. This approach ensures optimum cable routing and ideal readability. Setup of the PBS takes place in a simple, fast, and thus cost-saving way using three buttons - without any tools. The pressure switch is available in diverse variants featuring different output signals. On top of that, IO-Link is also available for extended operating and polling options.

For monitoring pressure at its hot-rolling mills, the leading Chinese bearing and special steel producer, Jiangyin Xingcheng Special Steel, also relies on the PBS pressure switch from SICK. In this connection, too, the accuracy and ruggedness of the maintenance-free sensor are crucial arguments in favor of the PBS.
