Maxwell-Wien Bridge Circuit
. The circuit proposed to receive data and to transfer power to the implant is a Maxwell-Wien bridge circuit
variation , shown in Figure 5.
* To determine the resistance change of the SG, it is operated in a Wheatstone bridge circuit
with a constant bridge excitation voltage of UB = 0.5 ...
This configuration measures an unknown electrical resistance balancing two legs of a bridge circuit
, one leg of which includes the unknown component.
"We are one of the best on the bridge circuit
, and people always fight for tickets!
In most cases, a stationary operated sensor in a controlled bridge circuit
is used, where its filament is kept on constant temperature.
The Model SDT transducer indicates the level of liquid by continuously measuring hydrostatic pressure via its sensing dement, an ion implanted silicon semiconductor sensor with integral Wheatstone Bridge circuit
. Once the sensor measures the pressure, its data is converted to 4 to 20 mA output signal (other outputs are available).
Based on sinusoidal commutation, motor drive power is developed within a MOSFET power bridge circuit
, which contours the output for each motor coil.
Most other pressure sensors transmit measurements using four piezoresistive elements arranged in a Wheatstone bridge circuit
. Since its sensor has a single piezoresistive pad, Motorola can put the mechanical diaphragm with electronic circuits that condition the signals on a single silicon chip.
The accelerometer has a two active arm, full bridge circuit
with fixed completion resistors to facilitate shunt calibration and incorporates a micro-machined piezoresistive sensor with integral mechanical stops.
The PWM signal controls the top switch in the half bridge circuit
while the inverse of this signal controls the bottom switch in the circuit.
The following equations (3) and (4) can be used as the measurement equations for a two-current-source bridge circuit
The series meets both SAE J211 impact testing and SAE J2570 anthropomorphic testing standards and features an advanced monolithic MEMS sensor design with integral mechanical stops for ruggedness, stability and reliability (US patents 4,498,229 and 4,605,919), incorporating a full bridge circuit
with fixed resistors for shunt calibration.
The load cell is a precision spring mechanism with strain gauges placed upon it that are arranged in a Wheatstone bridge circuit
. It may sound old fashioned but it's very stable.
