Abstract
A measurement probe (1) for a machine tool has a housing (4/5) incorporating a window (6) which allows the optical transmission or receipt of signals from/to infrared transmitters (12) or receivers (13). To obviate the need to mount the transmitter and receiver components on an external surface of the housing, they are surface mounted to a circuit board (8′).
Claims8
A measurement probe comprising a housing having at least one signal transmitter and/or receiver, and a circuit board therein and comprising a window transparent to the signal, characterised in that the said at least one transmitter and/or receiver is mounted to the circuit board adjacent the window.
A measurement probe as claimed in any one of the preceding claims wherein the circuit board is relatively rigid and has lines of weakness at which the board is bendable to be formed for positioning within the housing adjacent the window.
A measurement probe as claimed in any one of the preceding claims wherein the said at least one, or the said plurality of transmitters and/or receivers is/are optical devices operable in the infrared spectrum.
A measurement probe as claimed in any one of the preceding claims wherein the window is a filter.
A measurement probe comprising a two-part housing having a signal transmitter and/or receiver therein and comprising a window transparent to the signal, characterised in that the window is compressed between the two housing parts.
