LPS-C2 Series Differential Pressure Switch
Pressure measurement suitable for negative-pressure applications, enabling high- and low-limit alarms by comparing the measured pressure value with a setpoint. 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, delivering 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:
● Fully welded diaphragm, zero leakage
●Mechanical principle, no power supply required
● High-quality microswitch with minimal dead zone
● The process interface is versatile, and both flanges and threads can be customized.

● Fully welded diaphragm, zero leakage
●Mechanical principle, no power supply required
● High-quality microswitch with minimal dead zone
● The process interface is versatile, and both flanges and threads can be customized.
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:
