<p>A squarer comprising an electric heater (1) thermally contacting one of the working surfaces of a cooling means (2), that working surface also contacting thermally the first sensitive element of a differential temperature sensor (4). The second sensitive element of the temperature sensor (4) contacts thermally the second working surface of the cooling means (2), that working surface contacting thermally in its turn one of the working surfaces of a cooling means (3). The second working surface of the cooling means (3) contacts thermally a heat-dissipator (6). The squarer comprises as well a differential temperature sensor (5) the first sensitive element of which contacts thermally the second working surface of the cooling means (3), whereas the second sensitive element contacts thermally one of the working surfaces of the cooling means (2).</p> |
