Abstract: The invention relates to a belt for measuring physical quantities of an object, comprising at least one measurement sensor, a strip and a device for clamping the strip around the object. According to the invention, the belt comprises a pressing device for pressing the measurement sensor in a first orientation toward the object, comprising a casing attached to the strip, an intermediate part and a constraining member to have the intermediate part assume a first low position in which it presses toward the sensor in the first orientation, a lifting member, for holding the intermediate part in a second lifting position above the first low position against the constraining member, the lifting member being actuable from the outside of the casing to have the intermediate part pass from the second lifting position to the first low position in which it presses toward the sensor.

Abstract: The invention concerns a belt for measuring temperature of an object, the belt comprising: at least one measurement sensor, a strip having a circumference intended to surround the object, a device for clamping the strip around the object, characterized in that the temperature sensor is mounted on an individual heat-insulating support displaceable in a guiding direction toward the object between at least two heat-insulating pads which are intended to abut against the object, the pads being attached to the strip.

Abstract: The invention relates to a method of controlling switchgear in order to estimate the remanent flux value of a power transformer during disconnection from a high-voltage electrical network using voltage measurements delivered by a capacitive voltage transformer by correcting the transfer function of the capacitive voltage transformer, and in which said value is delivered to a controller that determines the optimum switchgear switching instant.

Abstract: The invention relates to a method for the detection and/or measurement of fouling in a heat exchanger, whereby the resistance value (R1, R2) of a resistor (R), placed on a wall (P) of this heat exchanger, is measured at two different instants and a value of the measurements (R2; R1) that corresponds to a function of the values measured at these two instants is determined, characterized in that the resistor (R) is subjected in succession to two power levels (P1, P2) that are each maintained for a certain duration, the first power level (P1) being below the second power level (P2), and the measurements of the two resistance values (R1, R2) being respectively carried out during application of these two power levels.

Abstract: Disclosed is an accessory mounted on a cutting device including two mutually parallel guide bars. The accessory includes a first channel formed in the accessory for receiving one of the two mutually parallel guide bars. A second channel is formed to receive the other of the two mutually parallel guide bars in such manner that the second guide bar is freely translatable in the second channel. An affixation device is firmly affixes the accessory to one of two mutually parallel guide bars.
