What is the difference between a standard analog transmitter and a smart transmitter?
This is a very interesting question as many manufacturers have their own definition on what is smart. So lets me simplify as there are a number of manufacturers that make true smart transmitters with world class manufactured performance.
A smart transmitter has a number of qualities and may not be limited to any one feature set. As a standard feature set they would include; some form of digital protocol (HART, FF, Brain, ModBus, DE, Profibus, etc.), remote configuration (no more climbing on tanks or troubleshooting in hazard areas.) internal self-testing, analytics and troubleshooting, analog output and possible fault/alarm switching, characterization of sensor for high performance accuracy, long term stability and repeatability performance guarantee's and be tested individually prior to shipping.
Analog transmitters that are lower cost typically take short cuts in manufacturing. Only 1 out of a certain number (10, 100, 1,000) of those manufactured will be tested and verified that they meet spec. They have a higher susceptibility to mechanical hysteresis which is a huge issue on pressure. They are extremely sensitive to any change in the environment. Low accuracy and limited promise of any repeatability. High cost of ownership based on MTBF typicals. (Most smarts today guarantee lifetime performance.)
All, in all if you work in a precision world and want something that is not maintenance prone the investment pays huge returns. I installed numerous units in a ugly Pharmacy application when I first came into the process world 30 years ago. They have not needed any calibration adjustments to date and are still fully functional. Only 2-3 failures after that time with several hundred transmitters of all types. (I will expire before they do.)
Now I am using them in Mission Critical data centers for efficiency improvement and gaining huge results in stability, efficiency and overall environmental sustainability.

What is the difference between analog and digital transmitter?
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
Difference between an analog and digital scope?
Analog can reach higher speeds.
What are the differences between a mounted digital kitchen scale and a standard analog kitchen scale?
The main difference between these scales it that the digital will give a more accurate and easier to read reading than figuring it out with the lines between the numbers the analog scale. However, the digital scale requires and battery and the analog does not.
What is the difference between CDs and VHS?
CD is a red-book digital audio storage standard and VHS is an analog video storage standard. CDs record data digitaly on a disk read with a lazer, whereas VHS tapes are analog and are read with an electromagnetic pickup.
What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
What is the difference between analog and digital altimeter?
Analog is displayed in a clock like instrument digital is shoun in numbers
Difference between analog audio and digital audio?
In analog ckt there is more distortion but in digital there is no distortion. Analog is a continues value digital is a discrite value(0 or 1). To measure analog is very difficult but in digital it is very easy. compare to analog the digital system is very compart for us. H.L.Kiran
what's the difference between analog and digital watches?
Analog is a clock with the moving hands on it, while digital is computer generated numbers.

The main difference between the tow is the signal. VGA uses an analog signal and DVI is a digital signal.
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
Are HD antenna different from analog antenna?
Not really. While some "HD" antennas are designed to minimize the effects of multipath reflections in large cities, there's no fundamental difference between an "HD antenna" and an "analog antenna". In a larger city where the TV transmitters are nearby and you have a good line-of-sight to them, you'll see no difference. The antenna is only used to pick up the air signal, which is on the same frequency band as old Analog TV. The only difference is the old-style analog NTSC (or PAL or SECAM) TV standard(s) used an analog carrier and the DTV ATSC standard uses a digital carrier. The whole "HD" + "Analog" antenna thing is basically hype.
