A brief review of the PS309 and PS409 Pressure Manometers offered by Validyne Engineering
Both the PS309 and PS409 pressure manometers offered by Validyne Engineering feature lightweight construction, absolute differential, and gauge ranges of 0.08 psi to 3200 psi FS. All surfaces that contact pressure media are 410 stainless steel in both units. There are, however, some differences. Let’s briefly review each manometer and cover some features and capabilities of each.
PS309 Pressure Manometer
As a totally self-contained pressure manometer, the PS309 is a portable unit that comes in gauge, absolute, and differential ranges. It offers a front panel liquid crystal digital display, as well as a 2 VDC analog output designed for remote recording or control.
For portable operations, the PS309 features a 3.5 digit LCD and battery pack (6-1.5V penlight cells), a solid-state electronics module, and integrated VR transducer. All surfaces that contact the pressure media are made from all corrosion resistant materials. It has ultra-low volumetric displacement with full-scale pressure exertion as well as very low internal cavity volumes.
The unit includes the capacity for individual meter scaling adjustments and, through easy front panel adjustment, decimal point selection for the display is user-programmable.
An optional feature of the PS309 is switch-selected Pressure and Flow operating modes. Each mode offers separate 2 VDC analog outputs and individual scaling adjustments.
PS409 Pressure Manometer
Designed for installation in rack-mount panels in laboratory and industrial applications, the PS409 pressure manometer we offer at Validyne Engineering is a self-contained digital indicator and sensor. It is ideal where accurate low-pressure readings are needed. The unit includes an integral VR transducer and easy-to-read 0.5 inch high x 4.5 digit LED display. It also offers a temperature range of 0ºF to 160ºF.
Digital Indicator of the PS409
The digital indicator offers read-outs in 3 different engineering units: PSI, In. H2O and In. Hg, which can be selected by the user from front panel buttons. Separate internal calibration adjustments for analog output and meter display are also featured.
Pressure Transducer for the PS409
Available in gauge, absolute, and differential versions, the PS409 is built of corrosion-resistant materials at points of contact with pressure media. The PS409 is available in 23 pressure ranges, from 0.08 to 3200 psi FS. The unit can also deliver 5 VDC analog output for remote display, control or recording purposes.
Applications of the PS409 include pneumatic systems, test cell and test panel applications, engine and vehicle test stands, pumps and hydraulic systems, process/product control testing, gas distribution, emission testing, and fuel pressure.
