product overview Product overview

The LPS-N4 series intelligent pressure switch is a rotatable intelligent product 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 or PNP/NPN switch signal, and the analog output supports 4-20mA current signals. It is more practical in situations where installation space is limited and the orientation of the meter head is required. If the pressure switch is tightened and the orientation of the meter head is not ideal, the meter head can be adjusted to rotate 330 °. 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 industries such as petroleum, chemical, metallurgy, water treatment, hydraulic equipment, lubrication equipment, etc.
