Electronic pressure switch SPE-S-3S

differentialSPDTG 1/4

Power 100 ~ 220VAC 3ch Digital Pressure Switch External Sensor Structure(4-20mA) Pressure Range -1 ~ 50bar This product is a digital pressure monitoring solution that replaces conventional mechanical pressure switches and gauges used in various refrigeration and air conditioning systems, offering enhanced convenience and functionality. It supports three pressure channels: high pressure, low pressure, and hydraulic pressure. Designed for precise control, the unit features both pressure-based band control and PID control functions, enabling efficient operation of variable-capacity compressors and inverter-driven outdoor unit fans. Additionally, the sensor-separable design eliminates the risk of leakage commonly associated with high-pressure hoses, ensuring safe and reliable operation.
