product overview Product overview

The LPS-N5 series intelligent pressure switch is an explosion-proof type pressure switch that can collect pressure values of on-site pipelines and pressure vessels, display them locally, output switch actions, and transmit signals remotely, making it easy for subsequent control and collection. The local switch control output is a dry contact SPDT, and the analog output supports 4-20mA current and RS485 output signals. Compared with mechanical pressure switches, it is very convenient to adjust the set value. At the same time, it can set multiple modes of single point alarm, alarm within the upper and lower limit range, and alarm outside the upper and lower limit range. Widely used in various industries such as petroleum, chemical, metallurgical, power, sugar, pharmaceutical, etc. that require pressure control
