Overview
Suitable for situations where the medium is corrosive, viscous, prone to crystallization, easy to solidify, and has solid floating particles. The diaphragm is filled with inert silicone oil, and the special material diaphragm contacts the material. The silicone oil conducts pressure to the sensor, and high and low limit alarms can be achieved by comparing the measured pressure value with the set value. The output signal is a passive dry contact signal (SPDT). It is commonly used for: 1. Acid exhaust gas pressure alarm; 2. Control of reactor pressure, etc; The pressure switch directly outputs the dry node signal, which can achieve the function of pressure transmitter+PLC/control instrument output switch control. The structure is simple, highlighting its advantages in on-site control in small-scale control. This product has the following features: ● Fully welded diaphragm, zero leakage ● Mechanical principle, no need for power supply ● High quality micro switch, small dead zone ● Diverse process interfaces, flange threads can be customized
Product Details
product overview Product overview
The LPS-M3 series diaphragm pressure switch is made by secondary diaphragm oil filling treatment on the basis of the basic pressure switch. The material for the liquid receiving part can be selected according to the characteristics of the working medium, mainly to deal with complex working conditions such as corrosion of the medium, viscosity of the medium, easy crystallization, or blockage of the pressure hole by particles. The interior of the diaphragm is filled with inert oil for pressure guiding purposes. Corrosive materials only come into contact with the special material diaphragm, and the deformation of the diaphragm is transmitted to the sensor through the oil. It can perform alarm actions or chain control such as high alarm, low alarm, high high alarm, and low low alarm on the medium pressure. The set value is adjustable, no separate power supply is required, and the contact capacity is large, which greatly facilitates on-site application for users. It is widely used in various industries such as petroleum, chemical, metallurgy, power, sugar, and pharmaceuticals that require differential pressure control.
measuring principle principle
Diaphragm pressure switch is a mechanical pressure switch that uses the mechanical deformation of the diaphragm to achieve the function of controlling contact closure and disconnection. When the pressure of the measuring medium changes, the diaphragm will produce corresponding displacement. The displacement of the diaphragm is transmitted to the micro switch through the transmission component. When the displacement stroke reaches the set value, the micro switch will be pushed, causing the contacts of the micro switch to close or open as a state variable. Adjustable pressure switches can control pressure within a fixed value or range by adjusting the stroke relationship between transmission components and micro switch contacts, in order to achieve control objectives.
