摘要:
A torque sensor arrangement including a contactless torque sensor, in which the torque sensor is arranged on an electrically operating linear carriage is provided. A distance sensor is also arranged on the linear carriage such that it allows the distance to the object of which the torque is to be determined to be measured.
摘要:
A magnetoelastic torque sensor (1) has an emission coil (7) for generating a magnetic field in an object (3), the torque of which is to be determined. The emission coil is axially oriented (A) and has an axial emission coil end surface (15) which can be guided towards the object (3). At least two reception coils (9, 33, 43) at a distance from the emission coil and having, respectively, a receiving coil end surface (17) which can be guided towards the object (3) to capture a response signal induced in the object (3) by the magnetic field of the emission coil (7, 31, 41). At least the receiver coil end surface (17) of one of the receiver coils protrudes beyond the emission coil end surface (15) to a selected distance from the object (3).

A method for investigating a magnetic workpiece (2) comprises the following steps:—measuring internal mechanical stresses on the workpiece (2) without a load;—measuring internal mechanical stresses on the workpiece (2) with a load;—setting up a calibrating function (7) by means of the two measurements for at least one measuring point;—measuring an externally introduced mechanical stress at the at least one measuring point while taking into consideration the calibrating function (7).

摘要:
At least one transceiver sends ultrasonic pulses through an object, which at least partially transmits ultrasonic pulses, into an element which reflects the ultrasonic pulses. The ultrasonic pulse(s) can be reflected in a temperature-correlated manner from the reflective element to the transceiver.
摘要:
A method for determining the temperature of an away-facing surface of an object, wherein at least one ultrasonic pulse is transmitted through a surface of the object facing a transmitter/receiver unit into said object; the at least one ultrasonic pulse is reflected at least partially in the direction of the transmitter/receiver unit on the surface of the object facing away from the transmitter/receiver unit; and the reflected part of the at least one transmitted ultrasonic pulse is received by the transmitter/receiver unit. At least one temperature value for the object surface facing the transmitter/receiver unit is also determined; at least one value is determined for the propagation time of the at least one ultrasonic pulse through the object, and at least one temperature value for the object surface facing away from the transmitter/receiver unit is determined by the at least one temperature value for the object surface facing the transmitter/receiver unit and the at least one propagation time value.

摘要:
A switching station for high or medium voltage offers a simple and practicable configuration for information transmission with a high security against failure. Panel devices are connected through a first bus line to a central control device. The panel devices feed a second bus line to which control devices of switching devices of the switch panel are connected. The second bus line is formed by an auxiliary line of the switching station.
