High Dynamic Range Current Measurement

High dynamic range high speed linac current measurements c.

High dynamic range current measurement. 1 current range depends on shunt value. This will power current sensing circuits so that no 60 v common mode voltage will disturb. With high side current sensing dealing with both a 60 v offset and high dynamic range current measurements requires some finesse. In order to keep energy consumption as low as possible these devices typically work with special sleep modes that consume very little power and are only interrupted by very short activity phases of normal or high power consumption.

Add a local low voltage floating dc supply like a battery which is attached to the power supplies positive terminal. Our various configurations of current sensors enable high accuracy fast response and high dynamic range current measurement. Measure sleep and transmit current without range switching. It is often used in the context of signals like sound and light it is measured either as a ratio or as a base 10 or base 2 doublings bits or stops logarithmic value of the difference between the smallest and largest signal values.

Powertrain current sensors require. Fringe projection profilometry fpp is a widely used technique for real time three dimensional 3d shape measurement. Dickson ornl oak ridge tn 37831 usa abstract it is desired to measure the linac current of a charged particle beam with a consistent accuracy over a dynamic range of over 120 db. High dynamic range and fast step response in one range.

It supports very high dynamic range as well as highest vertical resolution. First binary fringe patterns are projected to generate. In this paper we present a fpp method that can increase the dynamic range for real time 3d measurements. Plot current vs time estimate the battery life measure energy consumption find peak currents optimize the power consumption and much.

Current measurement with nine figure dynamic range a long battery lifetime is crucial for modern iot and mobile devices. Dynamic range abbreviated dr dnr or dyr is the ratio between the largest and smallest values that a certain quantity can assume. However it tends to compromise when measuring objects that have a large variation range of surface reflectivity. Simplify the current measurement battery life estimation of iot devices with the zs 2102 a.

In shunt mode two current measurement channels of the r s rt zvc02 zvc04 multi channel power probe are connected to the same shunt resistor see figure on next page. The high resolution adc technology used across the board in measurement technology already allows considerable dynamic ranges to be covered with a fixed scale design. A current measurement front end with 160db dynamic range and 7ppm inl international solid state circuits conference 5of 41 current input afe using. 2018 ieee 19 5.
