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.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
