Abstract
A thermoelectric connector module (C) is disclosed which comprises input (2) and output (1E) connectors and contains signal conditioning circuitry (1C). The input connectors (2) are interfaced with a hand-held detector (7), and the output connectors (1E) are connected to signal-utilising apparatus (11). The module does not contain a battery but receives its power supply for the conditioning circuitry from the signal-utilising apparatus supplied via the output connectors (1E). In this way, the module may be miniaturised, making it particularly suitable for mounting directly on a hand-held temperature detector or probe. Since the connector does not have to be opened for a battery replacement, it can be permanently hermetically sealed, providing resistance to dirt, dust, moisture, water and the like.
