Product Description
Product Overview Product overview
The LPS-N4 series intelligent pressure switch is a rotatable smart product that can collect the pressure values of on-site pipelines and pressure vessels, display them on-site, output switch actions, and transmit signals remotely, facilitating subsequent control and collection. The on-site switch control output is a dry contact SPDT or PNP/NPN switch signal, and the analog output supports a 4-20mA current signal, making it more practical in situations where installation space is limited and the orientation of the display is critical. If the orientation of the display is not ideal after tightening the pressure switch, it can be adjusted for a 330° rotation. Compared to mechanical pressure switches, it is very convenient for adjusting set values and can set multiple modes for single-point alarms, alarms within upper and lower limits, and alarms outside upper and lower limits. It is widely used in industries such as petroleum, chemical, metallurgy, water treatment, hydraulic equipment, and lubrication equipment.
