If your equipment fails, you’ll want to understand why. Often, a hydraulic system will fail due to unpredictable shifts and spikes in pressure within a unique environment. For example, a failure may be unavoidable if a spike exceeds a tool’s maximum rated pressure. Using a peak pressure recorder, you can understand whether a pressure pulse occurred, even if it was simply a momentary occurrence too small to be noticed by conventional methods.

The Lee Kipster^® Peak Pressure Recorder is a mechanical device that records peak pressure in a hydraulic system. The component contains a pressure-sensitive disc that deforms as a function of peak pressure. Although this device does not replace sophisticated transducers, it offers a simple, economical means of measuring peak pressure and a compact package that can be installed where electronic transducers can’t.

Lee Kipsters are available in three models that span the pressure range from 4000 psi to 30,000 psi with an accuracy of up to ± 3%. The pressurization rate has been shown to have little effect on the Kipster’s accuracy of up to 50,000 psi/sec. Above this rate, some drift may occur. If the pressure rise rate is repeatable, the drift is consistent within a given part number up to 2,000,000 psi/sec.

Improve hydraulic performance with Air Bleed Orifices from The Lee Company. These components are used to remove trapped air from hydraulic systems, increase system responsiveness, and improve reaction times. While traditional air bleed methods involve drilling a hole in the hydraulic manifold to allow the trapped air to escape back to the sump, this method also results in a continuous and significant hydraulic fluid loss. Instead, our components utilize a small precision flow orifice that allows trapped air to escape but is small enough to restrict most hydraulic flow, minimizing system losses. Our 5.5 mm diameter Air Bleed Orifices are offered in forward and reverse flow directions and contain an integral locking end for secure retention and sealing without threads, O-rings, or sealants. Both models contain integral safety screens for contamination protection.
