Low Pressure Variable Reluctance Sensor
DP45
The Validyne DP45 Very Low Differential Pressure Transducer is designed for extremely low pressure measurement in the order of 1 inch water column. This instrument is used extensively in connection with flow measurements where dynamic response at low flow rates is required. Dynamic line pressure effects are minimized due to the combination of low internal volume, symmetrical construction, and small volumetric displacement inherent in the DP45 design.

Speed Pick-up
SU63
The Validyne SU63 is an AC inductive speed pick-up used for RPM measurement on high-speed rotating equipment. The SU63 is a tightly-wound coil with a laminated core that can be conveniently mounted on rotating equipment so that the magnetic field of a magnetized nut or part passes through the coil windings. The moving magnetic field produces a voltage within the coil proportional to its rate of change and the strength of the permanent magnetized part. The frequency of this inductive voltage spike is fed into an oscilloscope or counter to determine RPM.
