Low Pressure Variable Reluctance Sensor
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.

Lake Variable Area Flow Meters
-
Lake Variable Area flow meters, often referred to as rotameters, measure flow rate of a liquid or gas by relating linear displacement of an internal “float” or sharp-edged orifice plate (Lake) to a corresponding flow rate. As flow rate increases, the orifice area that the flow moves through also increases – thus, the term “Variable Area.” Variable Area meters either allow flow through a peripheral orifice formed between a tapered wall and a float as in the traditional rotameter, or an annular orifice and an internal tapered metering pin in the Lake Monitor.

Programmable Step Attenuator, DC to 40 GHz, 0 to 11 dB, 1 dB steps
84904L
Attenuator
The Keysight 84904L programmable step attenuator offers coaxial measurements to 40 GHz in a compact, rugged design. It offers repeatability of better than 0.03 dB, excellent life (greater than 5 million switching cycles per section) and an attenuation range of 0 to 11 dB in 1-dB steps. This latest design evolution sets new standards for size and performance. High attenuation accuracy and low SWR are achieved through the use of miniature thin-film attenuation cards composed of high-stability tantalum nitride film of saphire substrate. Insertion loss is outstanding, with with only 2.4 dB of loss at 40 GHz. The compact size of the unit, 35% smaller than the Keysight 8495/7 (26.5 GHz) family, allows for easy integration into instruments and ATE systems.
