Core Features Dual Output for Comprehensive Pressure Pressure Management: Functions as a versatile pressure sensor switch combining a 4–20mA analog output with two configurable SPDT switches, engineered to provide both continuous pressure data and discrete control actions. This hybrid design eliminates the need for separate sensors and switches, streamlining integration into industrial systems requiring real-time monitoring and threshold-based automation. Medium Pressure Range with High Precision: Operates across a 0–60 bar (0–870 psi) range with ±0.3% full-scale accuracy, making it suitable for monitoring medium-to-high pressure liquids and gases. The sensor’s silicon piezoresistive technology with advanced temperature compensation ensures stable performance across -10°C to +80°C, critical for hydraulic systems, industrial compressors, and process control applications. Dual Configurable Setpoints: Equipped with two independently adjustable switch points that can be calibrated to trigger at user-defined pressures, with programmable hysteresis (1–4 bar) to prevent rapid cycling. This flexibility supports applications requiring both high and low-pressure alarms, pump staging, or valve actuation logic. Broad Fluid Compatibility: The 316 stainless steel wetted parts and FKM O-rings ensure compatibility with hydraulic oils, mineral oils, water, compressed air, and non-corrosive chemicals, making it versatile for heavy machinery, automotive manufacturing, and industrial cleaning systems. Robust Industrial Design: Housed in a die-cast aluminum housing with a corrosion-resistant coating, providing exceptional durability against mechanical impact and environmental exposure. The sensor achieves IP66 rating (IEC 60529) for dust tightness and high-pressure water jet resistance, ensuring reliability in factory floors, outdoor installations, and washdown environments. Flexible Integration Options: Features a 4–20mA analog output (2-wire, loop-powered) for continuous pressure data, compatible with PLCs, SCADA systems, and data loggers (e.g., Siemens S7-1200, Allen-Bradley Micro850). The switch contacts are rated for AC 250V (3A resistive) and DC 30V (1.5A resistive), supporting direct control of small motors, valves, or alarm systems. Simplified Installation & Calibration: Designed for process piping mounting via a 1/4-inch NPT male port, with an M12 circular connector for secure electrical connections. The sensor supports on-site calibration via a built-in potentiometer or remote configuration through compatible PLC software, simplifying setup in hard-to-reach locations. The compact housing (68mm × 48mm × 38mm) fits in space-constrained systems. Typical Applications The ALCO Switch PS3-A6S is engineered for integrated pressure monitoring and control in medium-to-high pressure industrial systems, with core use cases including: Hydraulic Machinery: Installed in injection molding machines, presses, or construction equipment to monitor hydraulic line pressure, providing analog data for system optimization and triggering switches to prevent overloads or cavitation. Industrial Compressors: Used in medium-pressure air or gas compressors to track tank pressure, with analog output feeding into energy management systems and switches controlling compressor on/off cycles or pressure relief valves. High-Pressure Cleaning Equipment: Integrated into industrial pressure washers or steam cleaners to monitor pump pressure, ensuring consistent cleaning performance while preventing damage from excessive pressure. Automotive Manufacturing Lines: Deployed in robotic welding or assembly stations to monitor clamping pressure in hydraulic fixtures, ensuring precise part positioning and quality control. Water Distribution Systems: Used in high-pressure water networks (e.g., for industrial cooling or fire suppression) to monitor line pressure, with switches activating pumps or valves to maintain optimal flow.
