Commercial Information – SICK PBT-RB040SG1SSFALA0Z

The Applications

1) Precision Force Control in Hydraulic Press Systems

Hydraulic presses rely on consistent pressure to form metal, mold parts, or laminate materials. When the PBT-RB040SG1SSFALA0Z is installed in the pressure line, it gives real-time readings that help the PLC maintain stable force during press cycles. Sudden loads, fluid temperature shifts, or valve movements can cause pressure spikes, and this sensor reacts quickly to keep those fluctuations in check. Maintenance teams can also identify seal wear or pump fatigue early by watching pressure drift over time. With reliable feedback, presses run smoother, tooling lasts longer, and operators avoid scrap caused by uneven forming force or unpredictable hydraulic behavior.

2) Cooling & Thermal Stabilization Systems in Manufacturing Cells

Industrial cooling loops—such as those used in CNC machining, injection molding, and automated welding stations—depend on steady pump pressure for heat removal. Installing this transmitter on the supply line helps operators ensure coolant flow remains consistent even when equipment cycles or environmental temperatures shift. If filters begin to clog or pumps lose efficiency, the pressure trend reveals issues early, reducing risks of overheating, thermal distortion, or unexpected shutdowns. With a stainless-steel build and fast signal response, the device fits well in aggressive coolant circuits, supporting precise temperature regulation and improving machine tool longevity and cycle-time stability.

3) Pneumatic System Health Monitoring & Energy Efficiency

Compressed air systems are essential in assembly plants, pick-and-place automation, and packaging lines. Using this sensor at the distribution header or key manifolds provides continuous visibility into pressure levels, allowing automation controls to react quickly if demand spikes or leaks develop. Stable pneumatic pressure means actuators move at predictable speeds and torque, preventing misalignment or missed cycles. Facilities can also track gradual pressure loss to detect worn hoses or fittings before they affect productivity. This approach helps lower energy waste from overworking compressors and ensures consistent machine response across shifts, improving throughput and reducing unplanned maintenance stops.

4) Pump & Filtration Skids for Process and Utility Fluids

Pump skids that manage water-based fluids, cleaning media, or industrial chemicals require dependable pressure feedback to protect valves, hoses, and filter elements. Placing the transmitter on the discharge line ensures operators and control systems see pressure changes immediately, enabling smarter pump speed adjustments or clean-in-place sequences. The device handles cycling pressure conditions and provides long-term stability, making it ideal for filter-loading applications where pressure gradually increases as media traps particulates. With accurate readings, engineers can optimize maintenance intervals, prevent pump cavitation, and maintain consistent flow quality, supporting better product yield and equipment durability in processing environments.
