The advantages and disadvantages of mechanical pressure switch is introduced
A, the advantages of the mechanical pressure switch is introduced
Compared with mechanical pressure switch electronic pressure switch, due to internal is a pure mechanical structure, so the price must be cheaper, and mechanical pressure switch does not need power supply, simple and convenient to use.Mechanical pressure switch has often opened two normally closed contact, pressure emergency alarm can be adjusted, mechanical long life, stable work.
B, the mechanical pressure switch disadvantages is introduced
Mechanical pressure switch to the purely mechanical structure movement, by mechanical deformation to switch, so the accuracy grade is low, generally less than or equal to 1.5% FS, although not charged operation, but after the need to achieve specified pressure through pressure action, and can not full range, seismic performance is poor, so if it is the vibration environment need to mechanical pressure switchin place after just can use.
Mechanical pressure switch due to the pressure switch is more traditional, also did not keep up with the pace of the intelligent electronic pressure switch, but also has been used in petrochemical, oil refining, drilling platform, and many other industrial sites.
