The disclosure relates to the absolute encoder of tubular motor, which solves the shortcoming of poor use performance of the tubular motor caused by the reason that the specific position of a roller shutter door or window cannot be sensed by measuring the operational state of the tubular motor in the operation of the tubular motor in existing technologies. According to the absolute encoder of tubular motor provided by the disclosure, an input shaft (1) drives through a speed variation device (2) a power shaft (5) to rotate; a code disc (6) is arranged on the power shaft (5); a sensing part is arranged on the code disc (6); a sensor (7) which is matched with the sensing part for collecting signals is arranged on a substrate (4); when a component which is driven by the tubular motor moves from one limiting position to another, the power shaft (5) rotates for one circle; the code disc (6) positioned on the power shaft (5) and the power shaft (5) rotate synchronously; and the travel of the component which is driven by the tubular motor is divided into a plurality of nodes by the code disc (6), so that the specific position of the component which is driven by the tubular motor can be sensed conveniently through the code disc (6) in the operation of the tubular motor, and the usability of the tubular motor is optimized.

In a separate encoder (100), a scale(102) is further provided with an ABS track(106) that is arranged in parallel with an INC track(104) and a detection head(110) includes an ABS detection portion (114) that reads the ABS track(106). The separate encoder (100) includes a calculation portion (120,220,320) that obtains a yaw angle (ϕ) of the detection head(110) with respect to a scale(102) based on a gap(d) between an INC detection portion (112) and an ABS detection portion (114) and a difference amount (δ) between a position(Xinc) of the INC track(104), which is detected by the INC detection portion (112), and a position(Xabs) of the ABS track(106), which is detected by the ABS detection portion (114). The calculation portion (120, 220, 320) also obtains a signal strength(I) based on two-phase sine wave signals(Am, Bm) that are output from the INC detection portion (112). The separate encoder (100) further includes a display unit(130,220,320) that displays a plurality of yaw angles (ϕ) and the signal strengths(I) corresponding to the respective yaw angles (ϕ).
摘要:
A method for measuring the absolute angle of rotation and an associated device are described. In such devices, a rotating element interacts with a converter which converts the rotational movement of the rotating element into a linear or curved movement of the converter. The distance covered by the converter on the basis of the rotational movement of the rotating element is measured and is used as a measure of the absolute angle of rotation. This makes it possible to flawlessly detect, in particular, angles of rotation >360° without a large amount of additional effort. The associated device has a corresponding measuring system with an evaluation unit.

摘要:
To provide a protective coat on a refrigerated sample collector for a corrosive environment a unitary frame includes a support unit with condenser and evaporator coils mounted to the support unit and an orifice connecting the condenser and evaporator coils. The evaporator coils, condenser coils and a restrictor are powder coated after being connected, whereby an effective seal is provided for the restrictor, condenser coils and evaporator coils after they are assembled to the support. The unitary frame can be easily removed or connected as a unit to the sample collector. The bottle rack for the sample collector is made by injection molding two halves of the rack each of which has a matching surface and a bottle positioning surface. The matching surfaces are fastened together by placing the matching surfaces together back to back whereby locating members are spaced apart a sufficient distance.

The invention relates to a process for locating a rotating drive part using a measuring system which comprises an absolute and an incremental partial measuring system. After the start of rotation, currently absolute position measuring values are determined and transmitted to a downstream evaluation unit until a reference mark reaches a known absolute position. At the reference mark there is a comparison of the measuring values, known from the current absolute position measurement, with the known absolute position and an optionally required adjustment is performed. The reference mark is subsequently used as the reference position for the incremental partial measuring system, the currently absolute position is indicated by the measuring system, and transferred to the evaluation unit in digital form.
