Differential Pressure Devices Threaded Deltadyne® Differential Pressure Indicators and Switches
Description
Operation
Deltadyne® differential pressure devices operate by sensing the differential pressure between ports upstream and downstream of the filter element. The differential pressure acts on a piston/magnet assembly that is contained in the Deltadyne device. When the differential pressure across the internal piston/magnet assembly reaches a preset value, determined by the range spring, the piston assembly moves downward sufficiently to reduce the attractive force between the magnet and indicator button or switch actuator lever. The indicator or switch spring then overcomes the reduced magnetic force to release the button or actuate the switch to signal the need for element change.
A magnet coupling isolates the pressurized fluid from the electrical or mechanical actuator. This eliminates dynamic seals and exposed cams, thus avoiding a leakage point common to other types of warning devices, particularly those which are connected to the bypass valve. Deltadyne devices respond only to differential pressures; they can withstand system pressures up to the design limit of 6000 psi (414 bar).

Deltadyne® Switches and Indicators
Electrical SwitchesDeltadyne® electrical switches have an automatic reset function that allows them to be used as system warm-up monitors. High fluid viscosity associated with low temperature start-ups will cause a higher pressure drop across the filter element. Deltadyne switches will signal high differential pressure until the system reaches operating temperature. As the system warms up, the differential pressure is reduced, and the range spring returns the piston assembly to its normal position, thus restoring the magnetic force between the magnet and the actuator lever. The restored magnetic force is sufficient to overcome the switch spring force, allowing the single pole double throw switch (SPDT) to signal a differential pressure below the switch setting.Single Pole Double Throw Switch:The SPDT switch allows this device to be used in a typical green-red light circuit. When the green light signals pressure drops below the actuation pressure, there is element life remaining. The red-light signals pressure drops above the preset value... either a cold start or the need for an element change. The two-light circuit also serves as a continuity check; one of the two lights should always be on. |

Visual IndicatorsMemory:All Deltadyne® visual indicators on the differential pressure device show whether a preset differential pressure has been exceeded at any time, even after the system is shut down. When the factory-set differential pressure is exceeded, the red button pops up and stays up until it is manually reset. When the differential pressure is reduced, the range spring returns the piston assembly to its normal position; however, the gap between the magnet and the now extended indicator button is too great for magnetic force to overcome the button spring force. The button, therefore, remains in the extended position until differential pressure is reduced and the button is manually reset.Thermal Lockout:An optional bimetallic thermal lockout prevents actuation below 32®F and allows actuation above 80®F system temperature. Between 32®F and 80®F the thermal lockout device is in transition. Above 80®F the indicator will actuate when the element is plugged and the differential pressure exceeds the pre-set limit. |
