3C-ISG121-031: Precision Sensing, Reliable Protection! Compact Electronic Pressure Switch Empowers Safety Control Systems

In hydraulic, pneumatic, water supply, and other industrial systems, real-time and precise pressure monitoring is crucial for equipment safety protection, process control, and energy management. The 3C-ISG121-031 electronic pressure switch integrates a high-precision pressure sensor, adjustable setpoints, and stable, reliable signal output, providing intelligent and dependable pressure monitoring and protection functions for modern automated equipment.Core Product Advantages

• High-Precision Electronic Sensing:​ Utilizes a high-performance pressure sensor (e.g., ceramic piezoresistive, silicon piezoresistive), offering high detection accuracy (typically ±0.5% FS), fast response, and strong anti-interference capability.
• Adjustable Setpoints:​ Allows flexible configuration of one or two independent switching points (e.g., high limit, low limit, or window comparison) via potentiometer, pushbuttons, or communication interface. The wide setting range adapts to different operating conditions.
• Multiple Output Signals:​ Provides NPN/PNP transistor switch outputs for connecting external relays or directly interfacing with PLCs. Some models support analog (4-20mA/0-10V) outputs and digital communication, enabling remote monitoring and parameter configuration.
• Compact, Rugged, and Environmentally Resilient:​ Housing typically rated IP65/IP67 for dust and water resistance. Pressure port is made of stainless steel for corrosion resistance, suitable for harsh industrial environments.
• Clear Status Indication:​ Equipped with LED indicators for real-time display of power status, switching action, and alarm information, facilitating on-site commissioning and fault diagnosis.

Typical Application Scenarios

• Safety Protection:​ Overpressure/underpressure alarm and shutdown protection in hydraulic/pneumatic systems to prevent equipment damage.
• Pump Station Control:​ Automatically controls pump start/stop based on pressure signals for energy-efficient operation (e.g., variable frequency constant pressure water supply).
• Process Control:​ Serves as a pressure arrival signal to trigger the next action in equipment like injection molding or die-casting machines.
• Energy Management:​ Pressure monitoring and interlock control for compressors and air compressor stations.

Technical Parameters (Typical Values)

• Pressure Range:​ 0 ~ 1.0 MPa or 0 ~ 2.5 MPa (“031” may indicate the range code)
• Accuracy Class:​ ±0.5% FS
