Pressure Transducers and Transmitters

DP103 Ultra Low Range Differential Pressure Transducer

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.

DP45 Very Low Range Differential Pressure Transducer

The DP45 Variable Reluctance Differential Pressure Transducer is designed for very low pressure measurements 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.

DR800 Draft Range Transmitter

The Validyne DR800 Draft Range Pressure transmitter is designed exclusively for very low industrial differential pressure measurements.

It has a true full scale as low as +/-0.25 In H2O without turndown or over-amplification. Spans as low as 0.1 In H2O are possible with standard models. Zero elevation and suppression adjustments allow calibration over the precise range of interest. The DR800 offers 0.5% FS accuracy and an operating temperature range of -20 deg F to +185 deg F. The total combined temperature effects are less than 3%/100 deg F.

P55 Industrial Pressure Transmitter-Transducer

The Validyne Model P55 is a compact differential pressure transmitter designed for industrial measurement applications.

The variable reluctance sensing technology allows the P55 to be used in a wide variety of low pressure measurements where fast dynamic response, high resistance to vibration and superior signal stability through ambient temperature change is required. The P55 will accept liquids and gases directly at the sensing diaphragm; there are no internal fill fluids to slow the sensor response or cause excessive temperature shift.
