⚙️ Operating Principle

Wireless transmitters operate as follows:

Process pressure is applied to the diaphragm.
The DPharp sensor measures the pressure difference with high accuracy.
The measurement signal is processed inside the transmitter.
The result is transmitted via the ISA100 wireless module to the control system.
