1, Principle and structure
The MS-T50 (exquisite) pressure switch/pressure controller has a built-in piston connected to a spring. When the pressure changes, the amount of spring expansion and contraction changes accordingly. When the pressure reaches the set value, it will trigger the preset mechanical structure and send out a switch signal.
2, Characteristics
The MS-T50 (exquisite) pressure switch/controller has a compact structure, uses DN standard plugs, is easy to wire, and has a wide measurement range. High overload capacity, high repeatability, specific normally open or normally closed contacts, gold-plated contacts, large contact capacity. Can be used for measuring water and oil pressure.

9, Adjustment method
**Step: Use a screwdriver to loosen the fixing nut of the protective cover and remove the protective cover and female plug (do not rotate the Husman connector left and right when removing to avoid breaking the internal circuit).
Step 2: Adjust the size of the pressure switch point with a screwdriver as shown in the diagram, increasing it clockwise and decreasing it counterclockwise.
Q: Could you offer the free samples ?
A: Yeah, but it depends products, Pls contact us ina@pneuhydr.com or whatsapp 0086 15168536055
Q: What ' s your business scope ?
A: Our business scope is service of exporter automation parts with full container, and sell air cylinder , air source treatment , solenoid valve , air valve, motorize valve , Brass valve, hydraulic valve, hydraulic cylinder, air and oil fitting, pressure gauge etc .
Q: What types of products you can make ?
A: We can make many kinds of stainless steel, brass ,aluminum materials processing .like high pressure Valve / solenoid valve / electric valve / water valve/pneumatic valve/air cylinder/hydraulic valve/hydraulic accumulator products and so on .
Q: Can the product be made with our logo and brand ?
A: Yes , of course , we can make . we are OEM supplier for years and professional to make . But you need give us the authorization if it is possible .

Q: Is there a warranty available?
A: Yes, normally products is one year quality guarantee.
Q: Is the connector in British or Metric system? What is the difference between PT, NPT, and G threads?
A: The G thread is cylindrical and does not seal itself, requiring additional gaskets to prevent leakage. PT and NPT are conical, and the internal and external threads become tighter and tighter when tightened. Sealing is achieved through the deformation of the threads, and sealant or tape is usually used in conjunction to enhance the sealing effect
G-thread is a cylindrical straight pipe used for non sealed connections; PT thread is a conical tube that relies on the deformation and sealing of the thread itself; NPT is also a conical tube with a tooth profile angle of 60 degrees, mainly used in North America
Q: How to convert pressure units: MPa, bar, psi, kg/cm ²?
A: 1MPa=10bar≈145psi≈10kg
Q:What usually causes the burnout of solenoid valve coils?
A:Incorrect voltage and hz, frequent switching, pilot head entering liquid,valve core and spring problem,environment hot,heavy vibration etc.
Q: What should be noted for pneumatic components in high temperature or extremely cold environments?
