Pressure Transmitter vs Pressure Switch: Understanding the Difference
In industries, pressure plays a very important role. Whether it is water, air, gas, oil, or steam, pressure must be controlled properly to keep machines safe and working well. Two very important devices used for this purpose are the pressure transmitter and the pressure switch. Many people think they are the same, but they actually have different jobs. Let us understand what they are, how they are similar, and what distinguishes them.
What is a Pressure Transmitter?
A pressure transmitter is a device that measures pressure and converts it into an electrical signal. This signal is sent to a control system, like a display screen or a computer in the control room.
For example, if a pipe is carrying water, the pressure transmitter measures the pressure inside the pipe and sends that value to the control panel. The operator can then see the exact pressure in numbers.
So in simple words:
A pressure transmitter tells you how much pressure is there.
What is a Pressure Switch?
A pressure switch is a device that turns something ON or OFF when pressure reaches a certain level. It does not show the pressure in numbers. Instead, it reacts when the…
