Pressure Transducers

The DP15 is a general-purpose differential pressure transducer that features field replaceable sensing diaphragms so that the full scale may be changed anywhere between +/-0.08 psid and +/-3200 psid. The DP15 is the most cost-effective way to make pressure measurements in the laboratory where pressure measurement requirements are constantly changing.

The DP15 has 23 different diaphragm ranges available. When used with a Validyne carrier demodulator, the DP15 can produce a +/-10 Vdc analog output proportional to the full-scale pressure range. The rugged construction of the DP15 makes it highly resistant to shock and vibration. Because the diaphragm is the only moving part, the frequency response of the DP15 to pressure pulsations is exceptionally high.

The DP15 will accept liquids and gases on both sides, and is constructed of 410 stainless steel. In addition, nickel and gold platings are available for aggressively oxidizing media. The O-ring seals are available in a variety of compounds. Bleed screws in each cavity facilitate liquid filling for dynamic pressure measurements.

The DP15TL is a general purpose differential pressure transducer that features a kit containing 7 field replaceable sensing diaphragms so that the full scale range of the sensor may be changed between +/-1 and +/-3000 psid. Using a companion carrier demodulator such as the CD15, the DP15TL is useful in a wide variety of laboratory applications where pressure measurement requirements constantly change.

The rugged construction of the DP15 sensor makes it highly resistant to shock and vibration. Because the diaphragm is the only moving part, the frequency response of the DP15 to pressure pulsations is exceptionally high.

The two symmetrical body parts are easily disassembled and reassembled with sensing diaphragms using the wrench furnished. The DP15 will accept liquids and gases on both sides, and is constructed of 410 stainless steel. The bleed ports in the sensor facilitate complete purging of liquid filled systems for dynamic measurements.

Spare o-rings, bleed screws, gaskets and an electrical connector are included in the handy storage box.

The DP45 low-pressure transducer is designed for pressure measurement in the range of +/-1 inch H2O. This transducer is used extensively in connection with flow measurements where dynamic response at low flow rates is required. Dynamic response is maximized by a combination of low internal volume, symmetrical construction and the small volumetric displacement inherent in variable reluctance design.

All surfaces exposed to the media are corrosion resistant 410 stainless steel. The design of the DP45 permits the user to disassemble the instrument for cleaning, diaphragm replacement or changing the full-scale pressure range.

When used with a companion carrier demodulator, the DP45 will produce an output of +/-10 Vdc for pressures as low as +/-0.6 inches H2O. The DP45 includes 10 feet of cable and an electrical connector as a standard option. Other cable lengths and extension cables are available.

The DP103 is designed for exceedingly low differential pressure measurement applications where high accuracy is required under rough physical and environmental conditions. With full scale ranges as low as 0.1 Inch H2O, even the most demanding low-pressure measurements are possible. The symmetrical pressure cavities and small volumetric displacement of the DP103 provide fast response for accurate dynamic pressure measurements.

Corrosive gases are easily handled, as all surfaces exposed to the pressure media are 410 stainless steel. Overpressures as high as 200% FS will not destroy the diaphragm and, with re-calibration, the instrument may continue to be used. When combined with a Validyne carrier demodulator, the DP103 will produce a +/-10 Vdc or 4-20 mA signal proportional to differential pressures as low as +/-0.1 In H2O. The DP103 comes with 10 feet of cable terminated by a connector in the standard configuration. Other lengths and connection options are available. With proper extension cabling, the DP103 may be located 1000 feet or more from the electronics.
