Product Overview

The SICK PBS plus pressure sensor is a robust, precision gauge pressure sensor designed for demanding industrial environments. It measures pressure in the range of 0 bar to 40 bar (0 psi to 580 psi) and features a durable construction with a stainless steel housing and plastic components optimized for long-term reliability. Equipped with an IO-Link interface, it enables seamless integration into modern automation systems through real-time data exchange. The sensor offers flexible output options including PNP/NPN digital signals and analog outputs (4 mA to 20 mA or 0 V to 10 V), making it suitable for a wide range of process monitoring applications. With a compact design, rotatable display, and IP67 enclosure rating, the PBS plus delivers reliable performance in both clean and harsh industrial settings.

Key Features and Technology

The PBS plus incorporates advanced digital communication via IO-Link V1.1 for intelligent diagnostics and configuration. Its 14-segment red LED display, with a character height of 9 mm, can be rotated electronically by 180°, enhancing readability from multiple angles. The sensor features a rotatable housing design: the display is aligned at 330° against the housing with electrical connection, and the housing itself rotates 320° relative to the process connection. A measuring chamber made of 316L stainless steel ensures high accuracy and corrosion resistance. Internal transmission fluid is silicone oil, available only for pressure ranges up to 10 bar (≤25 bar abs). The sensor supports both digital and analog output configurations with current consumption ranging from 45 mA to 70 mA depending on signal type.

Technical Characteristics

The SICK PBS plus operates within a process temperature range of –20 °C to +85 °C. It is rated for IP67 protection, offering full dust tightness and submersion capability up to 1 meter for 30 minutes. The sensor uses a G ½ B flush-mounted process connection made from 316L stainless steel. Supply voltage ranges from 15 V DC to 35 V DC, with a maximum total current consumption of 600 mA (including switching current). Electrical safety is ensured through protection class III, overvoltage protection at 40 V DC, short-circuit protection via QA, Q1, and Q2 fuses toward M, reverse polarity protection (L+ to M), and an isolation voltage of 500 V DC. The sensor weighs approximately 220 g and features a front-flush membrane pressure port.

Configuration and Integration

The PBS plus supports flexible integration through its IO-Link interface, enabling configuration and diagnostics directly from automation systems without the need for additional hardware. It offers PNP/NPN digital output options with either 4 mA to 20 mA or 0 V to 10 V analog signals, depending on application needs. The sensor uses a round M12 x 1, 5-pin connector for electrical connections. For configurations without analog output, the current draw is 45 mA; when analog output is active, it increases to 70 mA. The display update rate is adjustable at 1,000 ms, 500 ms, 200 ms, or 100 ms, allowing users to balance responsiveness and power consumption based on operational requirements.

Operating Environment

The PBS plus is designed for operation in industrial environments with ambient temperatures ranging from –20 °C to +85 °C. It is suitable for use in humid or dusty conditions due to its IP67-rated enclosure, which provides complete protection against dust and temporary submersion. The sensor’s internal components are constructed from high-grade materials: the lower body is made of stainless steel 304, the plastic head combines PC and ABS, buttons are TPE-E, and the display window is polycarbonate. These materials ensure durability under mechanical stress and environmental exposure. The sensor operates reliably within its specified pressure range (0 bar to 40 bar) and is compatible with standard process connections such as G ½ B flush mount.

Industrial Applications

The SICK PBS plus pressure sensor is ideal for use in a variety of industrial applications requiring accurate, reliable gauge pressure measurement. It is commonly deployed in pneumatic systems, fluid handling processes, and process control loops where real-time pressure feedback is essential. Its IO-Link capability allows integration into SCADA or PLC systems for continuous monitoring and diagnostics. The sensor’s robust construction and wide operating temperature range make it suitable for use in manufacturing, automotive, food & beverage, and chemical processing environments. With its rotatable display and flexible output options, the PBS plus supports both field maintenance and remote system control needs.
