Why and where a null detector is used?
Wheatstone bridgethe null detector is used to match a known quantity to an unknown onethe null detector has several sensitivity rangesat the highest sensitivity range you put almost no load on the device under test
Does having a metal plate in shoulder effect the metal detector?
No. The detector head cannot be turned to that amount of sensitivity anyhow and if you could it would drain the batterry very fast. You would also need a larger detector head. Just no.
Any metal detector available which detect iron and not aluminium?
Not necessarily. That would depend upon the metal detector design and the sensitivity settings.
How do you get metal through metal detectors?
In general, you can't get metal through metal detectors. Only the smallest bits of metal will not cause a metal detector to alarm. If the sensitivity of the detector is set too high, it may be possible to get a small piece of metal past the detector, but that is something that cannot be counted on.
How to trip a motion detector?
A: There are photo detector that sense changes in light as movement and there are frequency detectors that sense frequency shift as a person disturb the signal. Both are effective withing a certain range depending on environment and sensitivity. HOW TO TRIP IT IS UP TO YOU.
Disadvantages kelvin double bridge?
requires manual balancingsensitive null detector or galvanometer is required to detect balance conditionmeasurement current needs to be reasonably high to achieve sufficient sensitivity.
Can one adjust the sensitivity on a overly sensitive hard wired smoke detector?
Hard-wired "home" type smoke detectors can not be adjusted for sensitivity. Detectors that appear "too" sensitive are usually very dirty or located in the wrong place. Carefully review the lengthy instructions that come with each detector with regard to selecting a location. Avoid: high air velocity areas such as near air conditioner vents, areas outside bathroom doors where steam vapors waft out, kitchen areas where the cooking smoke can get to the detector before disapaiting Studio apartments pose an obvious problem. You can try cleaning the detector to make it less sensitive by following the manufacturer's cleaning instructions, but when in doubt, replace it. Isn't your life worth $10.00?
Why does my motion sensor stay on when it is dark?
Some times it is the wind that sets them off. I have trees that are close to the house that the sensor is pointed directly at. When the wind blows they trip the motion detector. If the sensitivity is turned up to the top it will pick up small animals. To set this sensitivity do a walk test at night. Get someone to walk past as you turn the sensitivity down. When the sensitivity is down so as not to pick the subject up give it a 1/4 turn to the plus side and that should stop needless tripping.
Can a metal detector find a buried mobile phone?
All metal detectors detect all metal depending on the level of sensitivity they are set at. Battery or no, a cell phone would be detected.
What is the difference between detector and diode detector?
difference between detector and diode
Which characteristic is shown when a person smells a gas in the air?
Sensitivity
What is the palindrome for detector?
"radar" is a palindrome for detector.
