  • Page 7: Introduction

    1 INTRODUCTION This document describes the TT SPM mechanical shaft power meter. The TT SPM combines a strain-gage based TT SPM Collar with a gyro RPM sensor to provide an all-in-one power measurement system. FUNCTIONAL DESCRIPTION 1.1.1 TORQUE MEASUREMENT The TT SPM is a strain gage transmitter. It is made to measure torque on rotating shafts using a 350 ohm torque pattern strain gage.

  • Page 13: Tt Spm Collar

    TT SPM COLLAR The TT SPM Collar is made to be installed on rotating shafts. It contains the following elements: • Strain gage signal conditioning and digitization • Gyro RPM sensor • Wireless radio module • Batteries The TT SPM chain-link architecture makes it scalable for various shaft diameters by adding or removing extension links.
  • Page 14 3.2.1.3 TIE KIT The tie links are used to attach the TT SPM Transmitter to the shaft. Figure 10 - Tie Kit 3.2.1.4 EXTENSION LINKS The extension links are optional collar links used to extend the collar diameter for shaft diameters above 150mm.

  • Page 15: Installation

    4 INSTALLATION TT SPM COLLAR INSTALLATION The following steps describe installation of the TT SPM Collar on a rotating shaft. 1. Locate an area with at least 250 mm of free horizontal space on the shaft. 250 mm (10 in) Figure 12 - Installation Area 2.
  • Page 16 3. Install the strain gage. See the following link for more details. https://binsfeld.com/support/torquetrak- support/torquetrak-support-strain-gage-installation/ 4. Is necessary, solder M8 connector cable wires to the strain gage (see Table 7 – Strain Gage Cable Connections). 5. Remove the TT SPM Collar from its packaging.
  • Page 17 11. Rotate the TT SPM Collar so the sensor link is aligned with the strain gage. Figure 15 - Positioning the TT SPM Collar 1. WARNING: ALWAYS apply anti-seize grease on M8 bolts threads before attaching the tie kit. Without grease, the stainless steel hardware will tend to seize when screwed together and may appear tightened when it is not.
  • Page 18 3. Tighten all the M6 pivot bolts around the collar to a final torque of 12N-m with a 4mm Hex Key. Figure 17 – Tightening Pivot Bolts 4. Connect the strain gage connector to the sensor link. Figure 18 – Connection of the Strain Gage 5.

  • Page 19: Tt Spm Receiver Installation

    TT SPM RECEIVER INSTALLATION The following steps describe the steps required to verify the connection between the TT SPM Receiver and the TT SPM Collars. 1. Install the TT SPM Receiver within 15m line-of-sight (of sensor link) or nearer to the TT SPM Collar. The signal strength must be greater than -80dBm (usually between -40dBm and -70dBm).

  • Page 23: Adjust Strain Gage Offset At Rest

    ADJUST STRAIN GAGE OFFSET AT REST Strain gages are very sensitive sensors. It is normal to read relatively large values after manipulating and installing strain gage because it adds small amount of mechanical stress on the gage itself. To adjust the offset the following operations must be done while the shaft is at rest (no spinning, no mechanical stress from the shaft).

  • Page 25: Maintenance

    6 MAINTENANCE BATTERY REPLACEMENT TT SPM is powered by 3.6V LiSOCL batteries, for example, model LS 17500 3.6 V Li-SOCl2 A-size bobbin cells from Saft (www.saftbatteries.com). These batteries have a low self-discharge and a high energy density. The battery voltage is expected to stay stable until approximately 5% of the battery capacity is left. When the voltage starts to drop significantly, it is recommended to plan battery change within a month.

  • Page 26: Modbus Registers

    7 MODBUS REGISTERS This section describes TT SPM Values through Modbus registers. VALUE TERMINOLOGY This section explains table headers for TT SPM values: Name: Name of the value. Description: Additional explanation of value. Type: Value data type, in signedness and length. Some values must be interpreted signed (negative and positive range, 2’s complement) or unsigned (positive range only).
  • Page 27 Modbus registers address space are the same for functions Read Holding Register and Write Holding Registers. Address space is zero based. Third party terminal software might use base address 40001 (decimal) for first Holding registers, but software still sends 0x0000 register address in Modbus frame. In this case, take TT SPM Modbus register (zero based) in decimal and add 40001 to get 40001 based register address.

    ALARMS DETAILS AND CORRECTIONS The following alarms resolution guide implies that alarms have been attempted to be cleared using procedure in section 8.2 ALARMS READING AND CLEARING. Alarms may change the data reliability read through Modbus registers. Alarms must be acknowledged (named warning below) or corrective measures must be applied. Alarm 1: Detail: Strain gage is disconnected or incorrectly connected to collar.
  • Page 33 Alarm 16: Detail: Receiver error while connecting to TT SPM Collar through wireless communication. Correction: 1. Check TT SPM Collar batteries: Were batteries replaced recently? Check if battery replacement is correct by reviewing section 6.1 BATTERY REPLACEMENT (validate sensor link reset). Did the collar operate for more than 1 year on the same batteries? Plan battery change.
