Vented VW Pressure Transducer
The vented pressure transducer is designed specifically for monitoring changes in water levels in wells and stilling basins.
The VW pressure transducer converts water pressure to a frequency signal via a patented* arrangement of diaphragm, a tensioned steel wire, and an electromagnetic coil. The pressure transducer is designed so that a change in pressure on the diaphragm causes a change in tension of the wire. An electromagnetic coil is used to excite the wire, which then vibrates at its natural frequency. The vibration of the wire in the proximity of the coil generates a frequency signal that is transmitted to the readout device. The readout or data logger stores the reading in Hz. Calibration factors are then applied to the reading to arrive at a pressure in engineering units.
Two Ranges: The vented pressure transducer is available in 22 and 50 psi ranges.
Large Diameter Vent Tube: The large diameter vent tube provides quick response to changes in atmospheric pressure and cannot be blocked by droplets of condensation.
Oversize Desiccant Chamber: The large capacity, low maintenance desiccant chamber keeps the vent tube dry for 3 to 6 months.
