Overview
Suitable for measuring the pressure values of liquids, gases, or vapors in explosion-proof environments. It can be controlled by local switch interlocking, display pressure values locally, and transmit signals remotely to the control system. Button operation sets action values and action modes. The switch output is a passive dry contact signal (SPDT). It is commonly used for: 1. Air compressor start stop control; 2. Pipeline pressure high and low limit alarm, interlock start stop pump, etc. The pressure switch directly outputs the switch signal, and the function can achieve pressure transmitter+PLC/control instrument output switch control. This product has the following features: ● Can be used in explosion-proof situations ● Multi channel switch output ● Local display of pressure value ● Multiple alarm methods can be set ● Button setting action value
Product Details
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
