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. |
