Q2. How dose RTD working
Ans. 
RTD stands for Resistance Temperature Detector, which measures temperature by changes in electrical resistance.
• RTD works on the principle that the electrical resistance of a metal increases with temperature.

• The RTD sensor is made of a pure metal, such as platinum, nickel, or copper.

• The resistance change is measured using a Wheatstone bridge circuit.

• RTDs are commonly used in industrial applications for accurate temperat...read more

Q3. How dose a pressure transmitter work
Ans. 
A pressure transmitter works by converting the pressure of a fluid into an electrical signal.
• Pressure from the fluid acts on a diaphragm inside the transmitter

• This causes a change in resistance, capacitance, or voltage

• The change is then converted into an electrical signal that represents the pressure

• The signal is sent to a control system for monitoring or control

• Example: A pressure transmitter in a boiler system measur...read more

Q4. How dose a vortex flow meter working
Ans. 
A vortex flow meter works by measuring the frequency of vortices shed by a bluff body in the flow stream.
• Vortex flow meters use a bluff body to create vortices in the flow stream.

• The frequency of vortices shed is directly proportional to the flow rate.

• The meter measures the frequency of vortices to determine the flow rate.

• Vortex flow meters are commonly used in applications where high accuracy is required, such as in t
