Pressure Switch

Honeywell pressure switches are used to provide electrical feedback in response to a chamber either rising or falling to a pre determined pressure level. These units feature a glass-reinforced polyester enclosure with a screw terminal connection capable of field adjustments and a Kapton diaphragm compatible for use with a wide variety of fluids. They are further designed to work in conjunction with different terminations (Metri-Pack connector) which forms a tight seal when connected. Choose from a broad range of these pressure switches available in 750 PSI and 1250 psi burst pressure variants on Raptor Supplies.

Features

  • Honeywell pressure switches feature a glass-reinforced polyester enclosure for durability and a diaphragm actuator to sense the pressure change.
  • These units have a Kapton diaphragm compatible for use with a wide variety of fluids.
  • They are further designed to work in conjunction with different terminations (Metri-Pack connector) which forms a tight seal when connected.
  • They are available in 750 PSI and 1250 psi burst pressure variants.

Working Mechanism

  • Apply pressure or vacuum to the sensing element.
  • Sensing element deforms in response to pressure or vacuum.
  • This causes the movement of a diaphragm or piston and activates a switch mechanism.
  • The switch mechanism then completes or interrupts an electrical circuit based on the pressure or vacuum level.
  • Finally, the electrical circuit controls associated equipment or triggers alarms.

Frequently Asked Questions

How do I install Honeywell pressure and vacuum switches?

  • Securely mount the switch using appropriate fasteners, ensuring it is positioned correctly.
  • Connect the electrical wiring to the terminals of the pressure or vacuum switch according to the wiring diagram provided.
  • Test the operation of the switch to ensure it functions correctly and responds appropriately to changes in pressure or vacuum.
  • If required, adjust the switch settings according to the application requirements.
  • Once tested and adjusted, securely fasten any connections and ensure they are properly insulated.
  • Conduct a final inspection to verify that the switch is installed correctly and is ready for use.

What factors should I consider while choosing a pressure and vacuum switch?

  • Select a switch with the necessary accuracy to meet your operational requirements.
  • Determine if the switch allows for easy adjustment of setpoints to accommodate varying pressure or vacuum levels.
  • Consider the response time of the switch to ensure it reacts quickly to pressure or vacuum changes as needed.
  • Assess the operating environment for factors such as temperature, humidity, and exposure to corrosive or hazardous substances, and choose a switch that can withstand these conditions.
  • Ensure the switch's electrical rating matches your system requirements to prevent overload or failure.
  • Choose a switch with mounting options suitable for your application, whether it's panel mount, pipe mount or other configurations.
  • Select a switch from a reputable manufacturer known for producing reliable and durable products to minimise the risk of failure.
  • Check if the switch meets industry standards and certifications relevant to your application, such as UL, CE or CS

What safety precautions should I take while using a pressure and vacuum switch?

  • Operate the switch within specified temperature, humidity and environmental conditions outlined in the manual to prevent damage or malfunction.
  • Follow electrical safety procedures when connecting the switch to power sources, such as turning off the power before installation, using insulated tools and wearing appropriate personal protective equipment.
  • Do not exceed the maximum pressure or vacuum rating of the switch to prevent damage or failure.
  • Periodically inspect the switch for signs of damage, wear or corrosion and replace any worn or damaged components promptly.
  • Establish procedures for emergency shutdown in case of switch malfunction or unexpected pressure / vacuum conditions.
