Product Overview

The SICK PBS pressure sensor is a robust, gauge-pressure measurement device designed for demanding industrial environments. It measures pressures from 0 bar to 40 bar (0 psi to 580 psi) and features a durable construction with a stainless steel housing and plastic components. The sensor includes an intuitive 14-segment red LED display with four digits and a character height of 9 mm, which can be rotated electronically by 180° for optimal visibility. With IO-Link communication support, the PBS enables seamless integration into modern automation systems, providing real-time data and diagnostics. Its flush-mounted G ½ B process connection ensures reliable sealing in harsh conditions, while the compact design with a total weight of approximately 220 g makes it suitable for space-constrained installations.

Key Features and Technology

The PBS pressure sensor leverages advanced sensing technology to deliver accurate gauge pressure readings. It features a measuring chamber made from 316L stainless steel, ensuring high corrosion resistance and long-term stability under process conditions. The internal transmission fluid is silicone oil, available only for pressure ranges up to 0 bar ... 10 bar or ≤ 0 bar abs ... 25 bar abs. A front-flush membrane pressure port ensures clean, reliable signal transfer. The sensor supports both digital (IO-Link) and analog output signals—PNP/NPN with 4 mA to 20 mA or 0 V to 10 V—and offers flexible configuration options. With a rotatable housing design allowing display rotation of up to 330° against the housing and 320° against the process connection, it adapts to various installation orientations. The sensor also includes comprehensive electrical safety features such as protection class III, reverse polarity protection, and short-circuit protection.

Technical Characteristics

The SICK PBS pressure sensor operates within a temperature range of –20 °C to +85 °C and supports measuring ranges from 0 bar to 40 bar (0 psi to 580 psi). It features an IO-Link V1.1 communication interface for device diagnostics, parameterization, and data exchange. The sensor uses a round M12 x 1, 5-pin connector for electrical connections. Supply voltage is provided between 15 V DC and 35 V DC, with total current consumption up to 70 mA (with analog output) or 45 mA (without analog output). The housing is constructed from stainless steel 304 (lower body), PC + ABS (plastic head), TPE-E (buttons), and a PC display window. Isolation voltage reaches 500 V DC, and the enclosure rating is IP67, offering full protection against dust and temporary immersion in water.

Configuration and Integration

The PBS pressure sensor integrates easily into industrial automation systems via IO-Link V1.1, enabling real-time monitoring, diagnostics, and configuration without requiring additional hardware. It supports both PNP and NPN output types with 4 mA to 20 mA or 0 V to 10 V analog signals. The sensor can be configured for different signal outputs depending on application needs—selecting between 45 mA (no analog) or 70 mA (with analog). The rotatable display allows users to adjust viewing angles up to 330° relative to the housing and 320° relative to the process connection. With a simple M12 connector, installation is straightforward, and the flush-mounted G ½ B process connection ensures secure, leak-free mounting in pipelines or vessels.

Operating Environment

The PBS pressure sensor is designed for operation in industrial environments with temperatures ranging from –20 °C to +85 °C. It is suitable for use in humid, dusty, and vibration-prone settings due to its IP67-rated enclosure, which provides complete dust protection and resistance to temporary immersion in water. The sensor’s process connection is made of 316L stainless steel, ensuring durability under aggressive chemical or thermal exposure. Internal components are protected by a silicone oil transmission fluid (only for ranges up to 0 bar ... 10 bar or ≤ 0 bar abs ... 25 bar abs). Electrical safety is ensured through protection class III, overvoltage protection at 40 V DC, and isolation of 500 V DC. These features make the PBS ideal for continuous operation in challenging process conditions.

Industrial Applications

The SICK PBS pressure sensor is widely used in industrial automation applications requiring reliable gauge pressure monitoring. It is suitable for use in pneumatic systems, fluid handling processes, and process control loops where precise pressure feedback is essential. Its robust construction and wide operating temperature range make it ideal for use in manufacturing, packaging, and chemical processing environments. The IO-Link interface supports integration into SCADA or PLC systems for real-time monitoring and diagnostics. With its compact size, high durability, and clear display, the PBS is well-suited for both fixed installations and mobile equipment where space and reliability are critical.
