Location of the label on the stator device. 2.2 The markings used in this document Important instructions for your safety are specifically identified. It is essential to follow these instructions in order to prevent accidents and damage to property.
8 Symbol Meaning This marking draws your attention to information about the product or about handling the product. Emphasis 3 Italics are used to emphasize and highlight texts. Application The torque flange measures static and dynamic torques on stationary and rotating shafts. Test beds can be extremely compact because of the short construction of the transducer. This offers a very wide range of applications. The torque flange is reliably protected against electromagnetic interference.
9 4 Structure and mode of operation The torque flange consists of two separate parts: the rotor and the stator. The rotor comprises the measuring body and the signal transmission elements. Strain gauges (SGs) are installed on the measuring body. The rotor electronics for transmitting the bridge excitation voltage and the measurement signal are located centrally in the flange.

11 5 Mechanical installation 5.1 Important precautions during installation NOTE A torque flange is a precision measurement element and therefore needs careful handling. Dropping or knocking the transducer may cause permanent damage. Make sure that the transducer cannot be overloaded, even while it is being mounted. • • Handle the transducer with care.
12 Important Even if the unit is installed correctly, the zero point adjustment made at the factory can shift by up to approx. 2% of the sensitivity. If this value is exceeded, we advise you to check the mounting conditions. If the residual zero offset when the unit is removed is greater than 1% of the sensitivity, please send the transducer back to the Darmstadt factory for testing. 5.2 Conditions on site The torque flange must be protected against coarse dirt particles, dust, oil, solvents and humidity.

14 5.4.2 Installation with subsequent stator mounting 2. Install shaft train 1. Install rotor Washers Fan-type lock washers 3. Dismantle antenna segment 4. Install antenna segment Support supplied by customer 4. Mount support Version b 13.01.
15 5.5 Mounting the rotor Tip Usually the rotor identification plate is no longer visible after installation. This is why we include with the rotor additional stickers with the important ratings, which you can attach to the stator or any other relevant test-bench components. You can then refer to them whenever there is anything you wish to know, such as the shunt signal. 1. Prior to installation, clean the plane surfaces of the transducer flange and the counter flange.
16 2. For the bolted rotor connection (see Fig. 5.9), use DIN EN ISO 4762 hexagon socket screws of the property class stated in Table 4.1, in a suitable length (dependent on the connection geometry, see Table 5.1 on Page 17). We recommend DIN EN ISO 4762 fillister head screws, blackened, smooth-headed, permitted size and shape variance in accordance with DIN ISO 4759, Part 1, product class A. Important Use a screw locking device (medium strength, e.g. LOCTITE No.

The upper antenna segment can be separated from the stator, for example, for maintenance or to facilitate stator mounting.

Undo and remove the bolted connections (M5) on the upper antenna segment. There are fan type lock washers between the antenna segments: Make sure that they do not get lost. 2.
19 4. Now tighten all antenna-segment bolted connections with a tightening torque of 5 Nm. 5. Then align the antenna to the rotor in such a way that the antenna encloses the rotor more or less coaxially and the antenna wire in the axial direction shows the position and the center of the transmitter winding on the rotor. Please comply with the permissible alignment tolerances stated in the specifications. Fig. 5.12: Alignment of the rotor with the stator 6.
20 Important To prevent this axial oscillation, the antenna ring requires additional support by the customer. There is a hole on the upper antenna segment (with M5 internal thread), which can be used to incorporate a clamping device (see Fig. 5.13). The cable plug also requires support in this case, a construction example is shown in Fig. 5.14. Fig. 5.13: Construction example for supporting the antenna ring Version b 13.01.
21 Fig. 5.14: Construction example for connector terminals (for two connectors) 5.7 Speed measuring system (optional) The optional speed measuring system has already been integrated into the transducer at the factory, no assembly is required. Magnetic ring for measuring the speed Sensor head for measuring the speed Fig. 5.15: Torque transducer with speed measurement Version b 13.01.
22 Speed measuring system sensor head alignment The speed measuring system is correctly aligned when the stator is precisely aligned for the torque measurement. So the two Allen screws on the sensor head (Fig. 5.16) must not be loosened. Important You must not change the position of the sensor head. Never loosen the screws! Sensor head for measuring the speed Fig. 5.16: Torque transducer with sensor head for speed measurement Version b 13.01.
23 6 Electrical connection 6.1 General instructions • With cable extensions, make sure that there is a proper connection with minimum contact resistance and good insulation. • All plug connections or swivel nuts must be fully tightened. Important Transducer connection cables from HBM with attached connectors are identified in accordance with their intended purpose (Md or n).
24 The cable shield is connected with the transducer housing. This encloses the measurement system (without the rotor) in a Faraday cage when the shield is laid flat at both ends of the cable. With other connection techniques, an EMC-proof shield should be applied in the wire area and this shielding should also be connected extensively (see also HBM Greenline Information, brochure i1577). Electrical and magnetic fields often induce interference voltages in the measuring circuit.
25 6.3 Connector pin assignment The stator housing has two 7 pin connectors, an 8 pin connector and a 16 pin connector. The supply voltage connections and shunt signal connections of connectors 1 and 3 are each electrically interconnected, but are protected against compensating currents by diodes. There is also an automatically resetting fuse (multifuse) to protect the supply connections against overload by the stator. Assignment for connector 1: Supply voltage and frequency output signal.
26 Assignment for connector 2: Speed output signal (optional).
27 6.4 Supply voltage The transducer is operated with a separated extra-low voltage (nominal (rated) supply voltage 18 - 30 VDC). You can supply one or more torque flanges simultaneously within a test bench. Should the device be operated on a DC voltage network1) , additional precautions must be taken to discharge excess voltages. The information in this Chapter relates to the standalone operation of the T40FM without HBM system solutions.
28 7 Shunt signal The torque flange delivers an electrical shunt signal that in measuring chains with HBM components, can be activated from the amplifier. The transducer generates a shunt signal of about 50% of the nominal (rated) torque, the precise value is specified on the type plate. After activation, adjust the amplifier output signal to the shunt signal supplied by the connected transducer to adapt the amplifier to the transducer.
29 8 Functionality testing You can check the functionality of the rotor and the stator from the LEDs on the stator. LED A rotor status LED B stator status Fig. 8.1: LEDs on the stator housing 8.1 Rotor status, LED A (upper LED) Color Meaning Green (pulsating) Internal rotor voltage values OK Flashing orange Rotor and stator mismatched (an increasing flashing frequency indicates the degree of misalignment) => Correct the rotor/stator alignment.
30 8.2 Stator status, LED B (lower LED) Color Meaning Green (permanently lit) Measurement signal transmission and internal stator voltages OK Green, intermittently orange. Orange until end of defective transmission if ≥5 incorrect measured values in sequence are transmitted. The measurement signals reflect the level of the defect status for the duration of the transmission defect + approx. another 3.3 ms.
31 9 Loading capacity Nominal torque can be exceeded statically up to the limit torque. If the nominal torque is exceeded, additional irregular loading is not permissible. This includes longitudinal forces, lateral forces and bending moments. Limit values can be found in the chapter "Specifications" (Chapter 13, Page 115). Measuring dynamic torque The torque flange can be used to measure static and dynamic torques.
32 10 Maintenance The torque flanges are maintenance-free. 11 Waste disposal and environmental protection All electrical and electronic products must be disposed of as hazardous waste. The correct disposal of old equipment prevents ecological damage and health hazards.
