Capacitance pressure transmitter is a pressure measurement device which convert applied pressure into a current signal. Capacitive type pressure transmitter is differential pressure type sensor. Principle: Capacitive pressure transmitter works under the principle of differential capacitance.
In this article, we discuss about How calibration is to be performed through decade resistance box for a conductivity transmitter. Image courtesy : Emerson analytical Theory : Conductivity is the ability of any solution to pass a electric current.
The LVR500 Series float level transmitter provides continuous level measurement up to 2 m (6.5') with a 4 to 20 mA signal output, and is factory configured to your selected dimension. This stainless steel liquid level sensor is well suited for high temperature or pressure tank level applications with relatively clean liquids such as water, diluted chemicals and light weight oils. Typical application examples include boilers and process vessels.
An optical transmitter is one half of a communications system, where the other half would be an optical receiver. Generating an optical signal is the job of the optical transmitter, which encodes the information to be transmitted on the light that it generates.
The transmitter must be easily modulated to meet waveform design requirements. The transmitter must be efficient, reliable and easy to maintain and the life expectancy and cost of the output device must be acceptable. The radar transmitter is designed around the selected output device and most of the transmitter chapter is devoted to describing ...
Beginner's guide to ultrasonic level transmitter. Sonic is the sound we can hear. Ultrasonic is the sound above human hearing range. Human can hear maximum up to a frequency of 20 KHz. Ultrasonic frequencies are above 20 KHz. Ultrasonic waves are used to measure level of liquids and solid objects in industries.
