sensors

sir im instrumentation i need more sensors the one u told abt level is too good
help me in the same way...........

will tell u after some search

simple sensors and controls for industrial automation
1. Thermostats from Dallas
2. RTCs from Dallas for timer control
3. simple LDR for light based switch control
4. some kind of custom made encoder for motor speed monitoring.. or use an already existing one..
5. Custom made smoke detector for fire control.

rest will add when i find..

flow sensor
rpm sensor/turn counter

An accelerometer is an electromechanical transducer which produces at its output terminals, a voltage or charge that is proportional to the acceleration to which it is subjected. The piezoelectric elements (similar to small crystals) within the accelerometer have the property of producing an electrical charge which is directly proportional to the strain and thus the applied force when loaded either in tension, compression or shear.

lvdt, for displacement
load cell.. for load
pressure transducers,
rotary encoders..
temperatures sensors.... LM35 etc...
ultra sonic Tx Rx pairs for fluid level

thaks toAJAY,ABBAS and SHYAM
but consider cost also
i need to implement na....
so plz.....consider cost.......... :-s

For sensors i mentioned in my post, I have kept implantation cost in mind.

i have been using all the sensors i mentioned. cud be a little expensive though i agree!!!

hey wt is the differenc b/w LM15 ,LM25 & LM35 all r temprature sensors......give brife....
