Differential Pressure Instruments Manufacturer & Supplier in India
What is a Differential Pressure Instrument?
A Differential Pressure Instrument is an industrial device used to measure the difference in pressure between two points in a system. These instruments are widely used for flow measurement, filter monitoring, level measurement, and process control in industrial applications.
Also known as DP Instruments, they include Differential Pressure Transmitters, Differential Pressure Gauges, and Differential Pressure Switches.
Saitechflow offers high-quality Differential Pressure Instruments designed for accuracy, durability, and reliable industrial performance.
Working Principle of Differential Pressure Instrument
The working principle is based on measuring pressure difference between two points:
ΔP=P1−P2\Delta P = P_1 – P_2
Where:
P₁ = High Pressure
P₂ = Low Pressure
The measured pressure difference is converted into electrical signal, mechanical indication, or switching action depending on the instrument type. This output is used for monitoring and controlling industrial processes.
