FAQs of Switch Contacts Tube Pressure Gauge:

Q: How does the magnetic snap action (micro switch) function in this pressure gauge?

A: The magnetic snap action micro switch provides instant, reliable switching with every activation. When the set pressure is reached, the single pole double throw (SPDT) switch actuates swiftly, ensuring precise control for industrial automation or safety shutdowns.

Q: What industries or applications are best suited for this pressure gauge?

A: This gauge is ideal for industrial automation, hydraulic systems, and process control due to its rugged construction, IP65 enclosure, and resistance to corrosion. Its well-suited for measuring the pressure of liquids and gases in demanding industrial environments.

Q: When should I choose the optional glycerin filling feature?

A: Glycerin filling is recommended when the gauge will be subject to vibrations or pulsating pressures. The damping liquid reduces needle fluctuations, ensuring accurate readings and protecting the internal mechanism from wear.

Q: Where can the gauge be mounted, and what are the available options?

A: The pressure gauge can be installed using bottom or back mount configurations. Accessories like mounting brackets and rubber gaskets are provided for secure installation on panels, machinery, or process lines as required.

Q: What is the process for electrical connection and what options are available?

A: The gauge offers two electrical connection methods: screw terminals or cable glands. Both options simplify wiring during installation, ensuring secure and efficient electrical contact for control or signaling circuits.

Q: How does the over-range protection benefit my system?

A: The gauge features 130% over-range protection, allowing it to safely withstand accidental pressure surges beyond its full-scale rating. This minimizes the risk of instrument damage and prolongs service life in fluctuating pressure environments.
