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.

High Voltage Pulse Attenuators
-
Barth High Voltage Pulse Attenuators are matched impedance coaxial attenuators for use primarily in pulsed 50 ohm systems, or where occasional transients would damage ordinary units. The attenuator design closely matches the impedance around each resistor, to that resistor. These attenuators feature an input impedance very close to 50 ohms, with characteristics as good or better than most microwave attenuators. These units are ideal for use in nuclear and high energy experiments. Extensive testing during manufacturing insures very high reliability for single-shot experiments. A voltage coefficient of the resistive film of less than .0001 %/V allows low voltage calibration of most systems.

Attenuators And Pulse Limiters
-
A bidirectional attenuator, i.e. the attenuation and power capability specification is valid for both directions. There is a large variety of applications for this attenuator: The measuring range of a spectrum analyzer can be increased. Any kind of meter can be protected against overload; it can be used to control the linearity of a meter reading. It can minimize measurement uncertainty caused by mismatched impedances. During an EMI receiver calibration an attenuator directly at the pulse generator output is inevitable.

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.

Fixed Attenuator
FAXE
-
Fixed Attenuators are waveguide components for introduction of some particular attenuation value in to the waveguide network for signal leveling or reflection compensation. The attenuators have two types of design: with resistive plate in the waveguide diagonal plane or using coupling technology. The FAXE 3, 6, 10, 15, 20, 30 dB attenuators are available in waveguide bands from 18 through 225 GHz. The FAXE Fixed Attenuators can be used as laboratory Standards against which other instruments or devices are calibrated in case the parameters of these Fixed Attenuators are stable enough and were measured with appropriate accuracy.
