How to select the working condition electrical contact pressure gauge？

Choosing the appropriate electric contact shock-proof pressure gauge is of great significance for ensuring the stability and safety of industrial processes. These instruments combine pressure measurement with electrical control functions and can operate stably in vibrating environments, being widely used in various industrial settings. The following will explain step by step how to make a reasonable selection.

1,First, the basic parameters applicable in the actual application need to be determined.    
This includes the type of measured medium, such as gas, liquid or corrosive substances; the range of working pressure, usually choosing a range that is about 1.5 times the maximum working pressure; as well as the working temperature and ambient temperature, all of which will affect the material selection and performance of the instrument. At the same time, the vibration level at the site needs to be considered, as the shock-resistant design is precisely for dealing with such working conditions.    
    
2, Determine the accuracy class    
The accuracy of electric contact shock-proof pressure gauges is usually divided into several grades, such as 1.0 grade, 1.6 grade, etc. The higher the accuracy, the generally higher the price.When making a choice, it should be based on the actual control requirements. There is no need to blindly pursue high precision. In ordinary industrial processes, levels 1.6 or 2.5 usually meet the requirements, while in precise control scenarios, higher precision may be necessary.    
    
3, Selection of interface material and specifications    
The interface materials of the instrument are diverse and must be able to withstand the corrosion of the measured medium.    
    
4,Set the parameters of the electrical contact points    
The electrical contact function is used to send a signal or cut off the circuit when the pressure reaches the set value. It is necessary to clarify whether it is upper limit control, lower limit control or double limit control. At the same time, the contact capacity should be determined based on the electrical load, such as voltage, current and AC/DC type. The repeatability and reliability of the contact action are also factors that need to be paid attention to.    
    
5,Select the appropriate model    
The product models from different manufacturers have their own characteristics. One should carefully compare the technical parameters. It is recommended to choose suppliers with production qualifications and quality assurance to ensure that the products comply with relevant industry standards. At the same time, one can refer to the evaluations and usage experiences of other users, but be careful not to be influenced by exaggerated promotions.    
    
6.Consider the seismic resistance and protection performance    
Due to the frequent vibration in the working environment, the shock-resistant design of the instrument is of great importance. The internal oil filling can reduce the oscillation of the pointer and enhance the stability of the reading. The protection level of the casing is also not to be overlooked. For example, the IP65 level can prevent dust and water, and is suitable for humid or dusty environments. The appropriate protection level should be selected based on the actual environmental conditions.    
 

7, Installation and Maintenance    
Correct installation is the prerequisite for ensuring the normal operation of the instrument. Forceful assembly should be avoided and good sealing must be ensured. Daily maintenance includes regular checks on the flexibility of the pointer, cleaning of the glass panel, and verification of the contact action. Any abnormalities should be dealt with promptly to prevent affecting the operation of the entire system.    
    
8, Budget and Cost Considerations    
Under the condition of meeting the technical requirements, one needs to balance the initial purchase cost and the long-term usage cost. Pressure gauges with excessively low prices may have potential problems in terms of material or manufacturing process. However, prices that are too high may exceed the actual budget requirements. It is recommended to select products with better value for money based on the overall budget. At the same time, consider the service life and maintenance costs, and comprehensively evaluate the overall investment.    

9,When choosing an appropriate electrical contact shock-resistant pressure gauge based on one's own working conditions and requirements, it is necessary to comprehensively consider the actual working conditions, technical parameters and cost factors. By gradually analyzing aspects such as measurement requirements, accuracy, material, electrical performance and environmental adaptability, one can select an instrument suitable for specific applications, providing support for the safe and stable operation of industrial equipment.
