Question

Accepted Answer

RTD, thermocouple, proximity sensor, flow meter, level measuring instruments, pressure measuring instruments, techo, PID control, control valve, pressure switch, weight feeder are all types of instrumentation devices used in various industries.

RTD stands for Resistance Temperature Detector and measures temperature using the principle of electrical resistance.
Thermocouples are temperature sensors that consist of two different metals joined together, generating a voltage proportional to the temperature difference.
Proximity sensors detect the presence or absence of an object without physical contact.
Flow meters measure the flow rate of liquids or gases.
Level measuring instruments determine the level of liquids or solids in a container.
Pressure measuring instruments monitor the pressure of gases or liquids.
PID control is a control loop feedback mechanism used in industrial control systems.
Control valves regulate the flow or pressure of a fluid in a process.
Pressure switches are used to sense changes in pressure and activate a response.
Weight feeders are devices used to accurately control and measure the flow of bulk materials.

RTD is a temperature sensing element it is positive temperature coefficient device when temperature increases than resistance increase it is generally two types pt100&pt1000 mean 100ohm =0degree,
Thermocouple is made of two different types material it works on the principal of seeback effect (two junction create on is hot and second is cold its output milivolt it is used very high temperature measurement it is various types as R,J,K,C,T use in industry as required.
Proximity sensor (metal detectors)it works when any metal object come on in front it is generally two types inductive and capacitive type it works on maximum 24volt DC supply in industry used where metal sensing required.
Different types flow meter as magnetic mass flow meter,coriolous mass flow meter,air and gas(vertex flow meter)etc their work principle and checking job in area etc used as required.
Level measuring instruments as like,side glass tube method, ultrasonic level measurement,radar level measuring instruments,DP level measuring instruments.
Pressure measuring instruments such as pressure gauge, DP transmeter etc.
Techo is a speed sensor device used in conveyer belt side and other places where proper speed checking in industry working principle and output checking.
Different types control valve such as butter fly,il control valve etc.
