Various Types of Process Instrumentation Transmitters
There are four basic types of transmitters that are used for process instrumentation. All of them have multiple common types that are used for various industrial applications.
Flow: As the name suggests, these transmitters provide measurements on the flow of liquid or fluid. This transmitter type consists of a transmitter and a flow sensor in one product. This allows it to generate an output up to 20mA. Flow transmitters are designed using different technologies, these include ultrasonic flow sensors, differential pressure flow sensors, and velocity flow sensors.
Temperature: The design of temperature transmitters includes a transmitter, and a temperature sensor. The sensor sends a signal to the transmitters, which calculates the temperature, and converts it into an output signal. There are two common types of temperature transmitters:
Thermocouple Type: A temperature transmitter with a thermocouple sensor is capable of calculating temperature by measuring the electromotive force created by a change in process temperature.
RTD Type: This temperature transmitter comprises RTD sensors, which change electrical resistance due to the change in process temperature. The relationship between these two aspects is used to calculate the temperature.
Pressure: These transmitters are used to measure pressure in different processes. Pressure transmitters are divided into three types:
Absolute Transmitter: This transmitter take vacuum pressure as its base, and then measures process pressure.
Gauge Transmitter: This type measures process pressure with the location’s atmospheric pressure as a base.
Differential Transmitter: When sensing units are introduced to multiple pressures as inputs, differential transmitters measure the differences between the various pressures.
Level: These transmitters are designed to measure the level of a liquid of solid within an enclosed space or vessel. There are seven types of level transmitters, which include:
Point Level: These are designed to provide an output signal when a particular measurement level has been reached. The output signal can be an electrical signal to turn on a switch, or an audible alarm.
Continuous Level: This transmitter measures level within a particular range. It is also designed to provide updated measurements as the level changes.
Ultrasonic Level Transmitter: Ultrasonic level transmitters allow for non-contact level measurements of bulk solids, or viscous liquids.
Conductive Level: This type is used to measure different types of liquids at point level. Liquids can include water, caustic soda, and hydrochloric acids, and other corrosive fluids.
Pneumatic Level: These transmitters are ideal for applications that comprise slurry or sludge. They can be used in applications that does not have electricity.
Capacitance Level: This transmitter type is used to provide continuous measurement of non-conductive liquids that have a high dielectric constant.
Hydrostatic based: As the name suggests, this transmitter relies on hydrostatic pressure to determine the level of a liquid.
When it comes to signal production, and process instrumentation, there are a variety of industrial transmitters to choose from. With these two posts, customers will have more knowledge when enquiring about transmitters for their industrial applications.

sir this videos usefull for me thank you....
Thanks, please share with others
Sir, well done and useful information.
Thanks
make a vdo on zinc rectifier , control wiring, diode explanation
Ok soon
Thanks for sharing.
Please make a video on AI, AO, DI & DO.
Ok
Great sir. Very informative.
Thanks, please share with others.
Very helpful information Sirji...
Thanks, please share with others.
@@ElectricalAndautomation_guru sure Sirji
Sir RTD ka output resistance hota hai aap ne bola mamp.
Great knowledge. Pls make videos on pt ft lt transmitter calibration in field or lab.
Okay
Great information
Thanks, please share with others.
Sir u mean a TT input is Ohms nd mV
How much pressure, temperature, flow should maintain, please explain if there any standards
No standards
Super fainstatic sir 💥💥👍
Thanks and sure, do not forget to share with others.
Sir please make a video how to program copy hmi to flash card
Ok, I will try.
Sir running plant mein DPT transmitter ko line mein kaise le and kaise remove karein please sir make one video on this
Already made a video on this topic, please go and see the video list
@@ElectricalAndautomation_guru ok sir
Nice information
Thanks, please share with others.
If water entry pressure transmitter. It will be damage..??
Yes
Bro Drop transmitter boleto kya hai please ek video Bana do bro
Ok
Pl make video on 3 element drum water controller
Already made a video on this topic, please see abs share your feedback
Hello sir
Can you make video about IMCC simocode pro
C, V , S with all details
Please 🙏🙏
I will try
Automanwal dpm caliberat ples sir
ok, thanks, please don not forget to subscribe our channel and don to forget to share with your friends in social media platforms.
tnx pls plc lecture share me

Ye kon sa plant he sir! 🧐
It is a Ethanol manufacturing plant
Ohh.. we are using in IOCL terminal for blending in MS! 👍🏻
👌👌👌🍺🍺
Thank you, please share with others.
Pratical me toda samjha eyi sir kam kar ke
Ok
