Pressure measurement suitable for negative-pressure applications—by comparing the measured pressure value with a setpoint, high- and low-limit alarms can be implemented. The output signal is a passive dry-contact relay (SPDT). Common applications include: 1. Vacuum pump start/stop control; 2. Vacuum level monitoring and interlock systems for pipelines or containers. The pressure switch directly outputs a switching signal, enabling functionality equivalent to that of a pressure transmitter combined with PLC/control instrumentation for switch-based control. With its simple design, it excels in local control scenarios within compact systems. This product features the following key characteristics: <br/> ● Fully welded diaphragm, zero leakage <br/> ●Mechanical principle, no power required <br/> ● High-quality microswitch with minimal dead zone <br/> ● The process interface is versatile, and both flanges and threads can be customized. <br/>

Suitable for applications involving corrosive, viscous, crystallizable, easily solidified media, or those containing suspended solids. The diaphragm is internally filled with inert silicone oil, while the special-material diaphragm directly contacts the process fluid. The silicone oil transmits pressure to the sensor, enabling high- and low-limit alarms by comparing the measured pressure value against preset thresholds. The output signal is a passive dry-contact relay (SPDT). Common applications include: 1. Acidic tail gas pressure alarms; 2. Reactor pressure control systems. The pressure switch directly outputs a dry-contact signal, offering functionality equivalent to that of a pressure transmitter combined with PLC/control instrument switching outputs. With its simple design, this product excels in on-site control scenarios within compact control systems. This product features the following key characteristics: <br/> ● Fully welded diaphragm, zero leakage <br/> ●Mechanical principle, no power supply required <br/> ● High-quality microswitch with minimal dead zone <br/> ● The process interface is versatile, and both flanges and threads can be customized. <br/> ● Switching difference is adjustable <br/>
