Abstract: A level sensing apparatus including an antenna structure having an active component to which an electrical signal is applied during use, and a reference component. A controller causes the electrical signal to be applied to the antenna structure and monitors the electrical characteristics of the antenna's electrical circuit. The controller causes the apparatus to switch between first and second modes of operation by causing as witch to connect the reference component to, or isolate it from, the electrical circuit.

Abstract: A belt monitoring apparatus (30) for monitoring a belt in a pulley system comprising at least two pulleys around which the belt is fitted. The belt monitoring apparatus (30) comprises a first sensing device (32) including a transmitter (42) configured to transmit a wireless signal and a receiver (44) configured to receive the wireless signal reflected, in use, by a span of the belt, and to produce a corresponding output signal. The apparatus (30) further includes processing means (36) configured to detect in the output signal a signal component caused by transverse vibration of the span and to determine the frequency of the transverse vibration from the span vibration signal component.
