A no emission tank gauge has a housing having a valve connection extending from a bottom side of the housing, a gauge line within the housing, the gauge line having a plumb bob attached at a free end, a pulley attached within the housing and supporting the gauge line, the pulley configured to allow extension and retraction of the gauge line, and an actuator connected to the pulley and extending exterior to the housing and configured to actuate the extension and retraction of the gauge line via rotation of the pulley. The housing has a window in a wall of the housing facing a marked side of the gauge line. The valve connection has an opening sized to allow for passage of the plumb bob and the gauge line. The housing is sealed when the valve connection is connected to a valve to prevent escape of fluid.

A traverse mechanism for measuring flow characteristics in a fluid flow path is provided. The traverse mechanism includes a rotating member configured to rotate 360 degrees about an axis in a circumferential direction. The traverse mechanism also includes a probe coupled to the rotating member. The probe extends in a radial direction relative to the axis through a portion the rotating member into the fluid flow path. Rotation of the rotating member enables the probe to map or measure one or more flow characteristic in the fluid flow path 360 degrees about the axis in the circumferential direction.

A rotary encoder includes a stator, a malfunction determination device, and a shaft having a bearing configuration internally connected to an axial bushing arranged in a housing. The bearing configuration provides for rotation of the shaft relative to the housing. A rotor is attached to the shaft. The malfunction determination device includes a detection device configured to determine whether a connection device is operably connected between a fixed portion of the encoder and the bushing, and to output the status of the connection to a control device. If there is no connection, the detection device determines a rotation of the bushing associated with a malfunction of the bearing configuration.

A sensor unit includes sensor constituent parts of various sensor devices and at least one printed circuit board that has voltage supply and signal transmission components for the sensor constituent parts and to which the sensor constituent parts are connected. The sensor unit has an annular base body that receives the sensor constituent parts and the at least one printed circuit board. A gear having such a sensor unit is also provided. A drive train having such a gear, a wind power installation having such a drive train, and an industrial application having such a gear are provided.

The bearing provides a first ring and a second ring centered on an axis, each of the first and second rings being provided with an outer cylindrical surface, with an inner cylindrical surface, and with lateral faces that axially delimit the outer and inner cylindrical surface. One of the inner and outer cylindrical surfaces and/or one of the lateral faces of the first ring includes a textured area provided with a groove extending circumferentially and with two protrusions disposed one on each side of the groove and extending along the groove.

A sensor bearing unit includes a bearing, which has a first ring and a second ring, both rings being centered on an axis, and an impulse ring. The impulse ring includes a target holder, a target mounted on the target holder, and a sleeve secured to the first ring of the bearing. The sleeve is provided with an axial portion having at least one radial protrusion and a collar extending at least partially radially. The target holder is mounted radially around the axial portion of the sleeve and axially between the first ring of the bearing and the collar of the sleeve. The at least one radial protrusion of the sleeve axial portion extends into a complementary recess provided on the target holder.

A rotation detecting device includes a member to be detected, and a sensor section arranged opposite the member to be detected. The sensor section includes two magnetic sensors, each including a detecting portion to detect a magnetic field produced from the member to be detected, with the detecting portions of the sensors being arranged in such a manner as to overlap each other in an opposite arrangement direction of the sensor section and the member to be detected, and a housing provided to cover the sensors together, and including an opposite surface to the member to be detected. The detecting portion of one of the sensors, which is arranged in a side of the sensor section close to the member to be detected, is arranged in such a manner as to be inclined with respect to the opposite surface of the housing.
