Validyne Engineering

DP103

The Validyne DP103 is designed for exceedingly low differential pressure measurement applications where high accuracy is required under rough physical conditions. With full scale ranges down to ±0.008 psid (±0.56 cmH2O), this instrument is being used in the measurement of very low flow rates of gases where symmetrical pressure cavities are required for dynamic response. It is also used in very small leak detection and pressure null detection systems.

DP15

An easy-to-replace pressure-sensing diaphragm maximizes the system’s functionality by making pressure measurements from ±2.22” H20 to ±3200 psi in one compact unit. Rugged and reliable, the DP15 provides superior accuracy for measuring low-pressure liquids and gasses, while it withstands the abuse of field and laboratory testing.

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.

DR800

The Validyne Model DR800 Draft Range Transmitter is designed exclusively for very low pressure measurement needs. It has a “true” full-scale range as low as ±0.25” H2O, making it ideal for air flow control applications. It can be turned down to ±0.1” H2O; higher full-scale ranges to ±100” H2O are available. The DR800 offers 0.5% accuracy and an operating temperature range of -20°F to +185°F. The total combined temperature effects are less than 3%/100°F.
