A programmable probe system for a machine includes a probe, an interface and a two-way optical communication link between them. The probe includes signal conditioning electronics, a power supply, a plurality of on/off switch circuits whereby the electronics may be connected to, and disconnected from, the power supply by a variety of means, for example, an optical signal, or a mechanical switch and a timing circuit. The probe also includes a microprocessor which can be externally programmed from the interface to select one or other of the on/off switch circuits. Where the probe includes a radio transmission for transmitting probe data to the interface, it is also provided with a synthesiser for generating different operating frequencies for the transmission system. The microprocessor can also be programmed from the interface to change the frequency of the system where required.

[ What is claimed is:] [1.]1. A programmable probe system for a machine comprising a probe, an interface and a wireless communication link therebetween, wherein:the probe has a plurality of modes of operation, each of which has a plurality of selectable states which are selectable by external programming, and includes a microprocessor which is programmed to select any one of said selectable states of any one of the plurality of modes of operation of the probe;the interface is mountable on the machine and includes a microprocessor which is externally programmable and determines for each one of said modes of operation of the probe which one of said selectable states is to be selected; andthe wireless communication link includes a transmitter on the interface for sending to the probe a signal which comprises program instructions for the microprocessor in the probe to make the selection of said one of the selectable states of at least one of the modes of operation of the probe as determined by the operator, and a receiver on the probe for receiving said signal to enable the microprocessor in the probe to make said selection.
