Core Features Versatile Medium-Pressure Monitoring: Functions as a multi-purpose pressure sensor switch designed for general industrial applications, operating across a 0–250 bar (0–3,626 psi) range with ±0.2% full-scale accuracy. This makes it suitable for monitoring a wide range of fluids, including hydraulic oils, coolants, and compressed gases in machinery, manufacturing lines, and power systems. Dual Output for Integrated Control: Combines a 4–20mA analog output for continuous pressure data with two configurable SPDT switches, enabling both real-time system analysis and discrete control actions (e.g., pump activation, pressure alarms). The analog signal provides precise insights into pressure trends, while the switches support threshold-based automation. Stable Performance in Fluctuating Conditions: Equipped with a piezoresistive sensing element with advanced temperature compensation, ensuring reliable operation from -20°C to +90°C. This stability is critical for applications with varying ambient temperatures, such as outdoor machinery or industrial ovens. Broad Fluid Compatibility: The 316 stainless steel wetted parts and FKM O-rings ensure compatibility with hydraulic oils, mineral oils, water-glycol mixtures, compressed air, and non-corrosive industrial fluids, making it versatile for factory automation, heavy equipment, and process control. Robust Industrial Housing: Housed in a die-cast aluminum housing with a corrosion-resistant epoxy coating, providing durability against mechanical impact and environmental exposure. The sensor achieves IP66 protection (IEC 60529) for dust tightness and resistance to high-pressure water jets, ensuring reliability in factory floors and outdoor installations. Flexible Integration Options: The 4–20mA analog output (2-wire, loop-powered) integrates seamlessly with PLCs, SCADA systems, and data loggers (e.g., Siemens S7-1200, Allen-Bradley CompactLogix). Switch contacts are rated for AC 250V (3A resistive) and DC 30V (1.5A resistive), supporting direct control of valves, pumps, or alarm systems. Simplified Installation & Calibration: Designed for pipeline 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, simplifying setup in diverse industrial environments. The compact housing (72mm × 50mm × 40mm) fits in space-constrained systems. Typical Applications The ALCO Switch PS3-A3S is engineered for medium-pressure monitoring in general industrial systems, with core use cases including: Hydraulic Power Units: Installed in industrial hydraulic systems to monitor line pressure, ensuring optimal performance of cylinders, motors, and valves while preventing overloads. Industrial Compressors: Used in medium-pressure air or gas compressors to track tank pressure, with analog data feeding into energy management systems and switches controlling compressor cycles. Machine Tool Cooling Systems: Integrated into CNC machines or metalworking equipment to monitor coolant pressure, ensuring adequate lubrication and preventing tool damage from insufficient flow. Power Generation Auxiliaries: Deployed in turbine or generator auxiliary systems to monitor lubricating oil pressure, providing critical data for preventive maintenance. Material Handling Equipment: Used in forklifts, cranes, or conveyor systems to monitor hydraulic pressure in lifting mechanisms, ensuring safe and efficient operation
