AI Thread Summary
The discussion centers on the market prices for capacitive sensors and tachogenerators, with an emphasis on their affordability for project inclusion. Participants note that while capacitive sensors are being considered, many similar devices are typically inductive or utilize hall effect technology. A suggestion is made to explore Dakota Digital for relevant products. The capacitive sensor is specifically mentioned for applications like water level sensing, while tachometers are highlighted for measuring motor speed to enable feedback control. Understanding the cost of these components is crucial for making informed project decisions.

Hi,

Anyone knows the market price for capacitive sensor and tachogenerator? I just want to know how cheap such devices can get, so that I can make a decision on whether I should include these extra features in my project, considering the total project cost.

Sorry for this weird question.

Why does it have to be capacitive? Most sensors of this type are inductive or hall effect. Try: www.dakotadigital.com Let me know if this is what you are after.
 
Capacitive sensors to sense the water level in a tank.

Tachometer to measure the angular velocity of the driving motors, so that I can apply feedback control on the speed o the motors.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
