Application The T12 digital torque transducer acquires static and dynamic torque at stationary or rotating shafts, determines the rotational speed or angle of rotation while specifying the direction of rotation, and calculates the power. It is designed for: highly dynamic torque measurements when testing the power and functionality of engines and compound sets ...
Signal flow Low pass LP1: 0.05 Hz to 4000 Hz Low pass LP2: 0.05 Hz to 100 Hz Low pass LP: 0.1 Hz to 80 Hz Fig. 4.1: Signal flow diagram The torque and the temperature signal are already digitized in the rotor and transmission is noise-free.
For settings over 100 Hz (torque low-pass filter 1 only), phase delay compensation is run for the angle of rotation signal. This ensures that torque and angle of rotation values that are measured simultaneously are also output simultaneously. Two pulse strings, offset by 90, are also available as RS422-compatible signals for rotational speed and angle of rotation.

Comply with the mounting dimensions to enable correct operation. An appropriate shaft flange enables the T12 torque flange to be mounted directly. It is also possible to mount a joint shaft or relevant compensating element directly on the rotor (using an intermediate flange when required).
Darmstadt factory for testing. 7.2 Conditions on site The T12 torque transducer is protected to IP54 according to EN 60529. Protect the transducer from coarse dirt, dust, oil, solvents and moisture. During operation, the prevailing safety regulations for the security of personnel must be observed (see “Safety instructions”).
7.4 Installing the slotted disc (rotational speed measuring system only) To prevent damage to the rotational speed measuring system’s slotted disc during transportation, it is not mounted on the rotor. The customer must attach it to the mounting ring before installing the rotor in the shaft train. The mounting ring and the associated rotational speed sensor are already mounted at the factory.
7.5 Installing the rotor Usually the rotor type plate is no longer visible after installation. This is why we include with the rotor additional stickers with the important characteristics, which you can attach to the stator or any other relevant test-bench components.
Page 20
1. Prior to installation, clean the plane faces of the transducer flange and the counter flange. For safe torque transfer, the faces must be clean and free from grease. Use a piece of cloth or paper soaked in solvent. When cleaning, make sure that you do not damage the transmitter coils.
Important Use a threadlocker (medium strength, e.g. LOCTITE) to glue the screws into the counter thread to exclude prestressing loss due to screw slackening, in the event of alternating loads. NOTE Comply with the maximum thread reach as per Table 6.1. Otherwise significant measurement errors may result from torque shunt, or the transducer may be damaged.

(option), see Chapter 7.7.3 . Fig. 6.11: Mounting holes in the stator housing (viewed from below) With the T12/5 kN@m and T12/10 kN@m torque transducers, we recommend additionally supporting the stator at the protection against contact. Fig. 6.12 shows an example of how to attach an angle bracket with a bolt (A) or with a threaded rod (B).
Section through the countersunk hole in the protection against contact Fig. 6.12: Supporting the stator with an angle bracket (5 kN@m and 10 kN@m) 7.7.1 Preparing with the mounting kit (included among the items supplied) The supplied mounting kit contains self-adhesive spacers, to make it easier for you to align the stator to the rotor.
Page 29
Radial alignment with spacers The spacers should preferably be attached to the transmitter head, offset by 90, as shown in Fig. 6.14. If your stator is equipped with a rotational speed measuring system, you must either shorten the spacers to an appropriate length or attach them slightly offset, next to the rotational speed measuring system.
Outer edge of transmitter head Red line Fig. 6.15: Axial position of the spacers Now remove the protective film and attach the spacers to the transmitter head, as described. Important Remove the spacers after installation. 7.7.2 Aligning the stator 1. Position the stator on an appropriate mounting base in the shaft train, so that there are sufficient opportunities for horizontal and vertical adjustments to be made.

When data are being exchanged via the CAN Bus or the PROFIBUS, the LED flashes green. You can also use the T12 Assistant to check for the correct alignment. The LED must stay green in the “Rotor clearance setting mode”.
7.7.3 Stator installation over the protection against contact (option) You can also axially flange the stator over the protection against contact (material: aluminum). Holes are provided in the side parts of the protection against contact for this purpose. For this mounting, we recommend M6 fillister-head screws with hexagon sockets in accordance with DIN EN ISO 4762;...

Electrical connection 9.1 General information Detailed instructions for connecting the T12 to the CAN Bus or the PROFIBUS can be found in the “T12 CAN Bus/PROFIBUS” interface description (in pdf format) on the T12 system CD. To make the electrical connection between the torque transducer and the measuring amplifier, we recommend using shielded, low-capacitance measurement cables from HBM.
Page 38
3 loops Fig. 6.21: Installation Example If the core has to be removed for any purpose (e.g. for maintenance), it must be replaced on the cable. Use only wounded core (toroidal core) of the correct type. Type: Vitroperm R Model No.: T60006−22063W517 Size: external diameter x internal diameter x height = 63 x 50 x 25 The core should be placed as close as possible to the connector.
9.2 Shielding design The cable shield is connected in accordance with the Greenline concept. This encloses the measurement system (without the rotor) in a Faraday cage. It is important that the shield is laid flat on the housing ground at both ends of the cable.

Important If plug 3 is used to power the device a tape wound core (toroidal core) is nec- cessary to suppresse high frequencies in order to ensure compliance with FCC regulations. NOTE Do not use cable KAB149 to connect the voltage output signal at AP01i to ML01B of the MGCplus system! This cable is only suitable for connecting the frequency output signal.
DC voltage network , additional precautions must be taken to discharge excess voltages. The notes in this section relate to the self-contained operation of the T12 without HBM system solutions. The supply voltage is electrically isolated from signal outputs and shunt signal inputs.
Page 44
voltage (24 V) can be up to 50 m long and in the nominal (rated) voltage range, 20 m long (see Accessories, page 88). If the permissible cable length is exceeded, you can feed the supply voltage in parallel over two connection cables (plugs 1 and 3). This enables you to double the permissible length.
Shunt signal The T12 torque transducer supplies a shunt signal, at either 50% or 10% of the nominal (rated) torque, as selected. Activate this function via the T12 Assistant or the shunt signal trigger on plug 1 or plug 3 (see Section 9.3). The last shunt selected in the T12 Assistant is then triggered.
The torque transducer is suitable for measuring static and dynamic torques. The following apply to the measurement of dynamic torque: The T12 calibration run for static measurements is also valid for dynamic torque measurements. The natural frequency f...
A template is also stored, which provides the conversion factors for the different physical units. The T12 is a transducer, that is to say, the T12 does not read the TEDS blocks, it only writes them. (We therefore strongly advise against editing the values with the HBM TEDS Editor, for example!) You can read the data of the TEDS block with the TEDS Editor.

Maintenance The T12 torque transducer without a rotational speed measuring system is maintenance-free. Cleaning the rotational speed measuring system During operation and depending on the ambient conditions, the slotted disc of the rotor and the associated optical system of the stator sensor can get dirty.
Packaging The original packaging of HBM devices is made from recyclable material and can be sent for recycling. Store the packaging for at least the duration of the warranty. In the case of complaints, the torque flange must be returned in the original packaging.
