Features and Overview

• Trip-free manual reset
• Maintenance-free design
• Single-pole, single-throw, normally closed contacts
• Factory calibrated pressure set points
• Hermetically sealed sensor

The 29PS HVAC pressure switch utilizes a snap-acting stainless steel Klixon disc that reverses its curvature when pressurized above a customer specified actuation pressure.  When the disc snaps it opens a set of electrical contacts by means of a transfer pin.  Resetting of the switch must be accomplished manually by pressing the integrated reset button.

The unique latching mechanism in the 29PS HVAC pressure switch design assures safe electrical cutout even if the reset button is held fully depressed.  This trip-free design prevents the consumer from restarting the equipment until the line pressure has dropped below the release setpoint.

The welded, hermetic sensor of the 29PS HVAC pressure switch provides increased reliability and maintenance-free operation for the lifetime of the switch.  The actuation and release pressures of the disc are factory calibrated, simplifying installation and helping make the 29PS HVAC pressure switch tamper resistant.  The epoxy potting and rubber boot provide an enviornmental seal for the switch mechanism, protecting it from dust, oil and moisture.

the 29PS HVAC pressure switch is a derivative of the Klixon 20PS HVAC pressure switch, long recognized as an idustry standard control device.

Features and Overview

• Electrically rated up to 480 Vac
• High current capability
• Capable of 2.5 million cycles (requires Sensata/customer specification closure and validation testing before application approval)

A breakthrough in Sensata Technologies’ pressure switch technology enables direct line break capability in applications that have been traditionally controlled in pilot duty circuits by contactors or relays.

The 46PS HVAC Pressure Switch is capable of breaking 2 amp loads at 480 Vac for 2.5 million cycles (requires Sensata/customer specification closure and validation testing before application approval).  It is ideal for cycling condenser fan motors to maintain an acceptable condensing pressure during low ambient temperature conditions.

In applications such as split room air conditioning systems, the 46PS as a head pressure control can result in significant cost savings when used instead of a pilot duty switch and relay.  Other potential uses include fluid pressure sensing in commercial and industrial applications.
