  • Optimizing the Digital Potentiometer in Precision Circuits
    potentiometer is followed by a high impedance. node, errors caused by the wiper resistance are elimi-. nated. PW. PA. PB. The absolute value of these resistances will still vary. between. R2 (1/2 of a dual Digital Potentiometer). ±20% and ±30% (depending on the device. used), however as shown in the table
  • Choosing potentiometers for position sensing
    . Exposed potentiometers are economically priced and very cost effective in high quantities. However, as its name says, the system is entirely exposed. However, one brand of potentiometers, SENSOFOIL, are printed with a polymer coating made up of nano-particles with lotus surface effect. Therefore, dirt
  • Using a Digital Potentiometer to Optimize a Precision Single Supply Photo Detect
    of the inverting. bandwidth of operation. input of the MCP601 CMOS amplifier is extremely high,. the current generated by the photodiode flows through. the feedback resistor (RF). In this configuration, the. feedback resistor is implemented with a digital. potentiometer (MCP41100). DS00692B-page 2
  • Case Study: Sensors for Conditioning Monitoring High Voltage Switching
    Conditioning monitoring on high voltage switchgear for the supply of mains electricity is an important function for preventative maintenance to ensure continuity of supply to consumers. The high voltage switchgear at major power distribution facilities operates in a very harsh environment with very
  • Plastic Machine Retrofits
    In an industry where we have long provided reliable, high performance position feedback, MTS Temposonics sensors are often utilized to bring new life to older equipment. Whether it be to replace potentiometers or multiple mechanical limit switches with linear feedback, we have the right solution

    and. processed. Since the tri-level (or trinary­ low, medium or high) resistances. produced by specific segments depends on parallel and anti-parallel domain wall. combinations as well as the number of rotations, the count can be accurately. determined. Because these are purely magnetic phenomena
  • Low-Cost Electric Range Control Using a Triac
    . A triac is. a three-terminal bidirectional AC switch that is triggered. by a low-energy signal applied to the gate. When this. signal is applied, the triac goes from a high-impedance. state to a conductive state, allowing current to flow to. the load. A positive or negative gate signal will trigger
  • Absolute positioning on a budget
    . with high accuracy and low operating costs. However, budgetary. constraints ruled out traditional approaches using servo or stepper. technology - which, given the small range of adjustment required, might. have been overkill for this application. In the end, it took an innovative. combination
