RFC Sensor This unit contains the RF transmitters and receivers for creating and monitoring the sensitive electromagnetic field.

Pressure Sensor This unit houses the pressure sensing diaphragms that detect the pressure differences between the tubes.

DPS Peripheral This unit collects the signals from the RF and Pressure sensors and performs the complex signal analysis to determine the alarm criteria. It also acts as the communications interface to the central control system.
Compensating Valves - These units are used to perform the self-compensation feature of the system. The body of the valve is of a special material suitable for direct burial without deterioration.

RF Cable This is the leaky coaxial cable that is used for the transmit and receive cables, buried along side the tubes.

Tube This is the underground pipe used to transmit the pressure signals to the pressure sensor unit. A special synthetic mix is used to provide the correct elasticity factor and underground durability.
