  • MCRT® 39000X devices from S. Himmelstein accurately measure torque for control and verification of loads on oil rig support legs. They enable load monitoring during jacking operations and help maintain stability on uneven and shifting sea beds and strong currents.

    Mounted between the electric motors and pinion drive gearboxes on each leg’s truss, the system transmits data via a two-wire 4-20 mA loop to the Control Room. Because the MCRT® 39000X torque instrument measures the source load distribution directly it enables a significantly faster response time than other systems. No need to guess the location of stress on the rig’s structure. This advance warning of any change or movement of weight helps prevent damage to decks and jacking equipment.

    Because of its extremely high immunity to noise interference, high safety margins, and maintenance-free design, the MCRT® 39000X has been certified by both ABS and DNV  to become a standard for oil field use.

    MCRT® 39000X torque transmitters measure bidirectional static (stall) and dynamic shaft torque and speed (an option).A one piece stainless shaft carries bonded, foil strain gages. They measure torque, and in combination with element design, cancel bending and thrust loads. Their rotary transmitters don't wear or generate noise. They are immune to ambient noise, vibration, lubricants and other hostile environments.

    There are no slip rings, brushes, radio transmitters and other noisy, limited-life elements. Unlike ferrite transformers, S. Himmelstein ferrite-free MCRT® 39000X units aren’t susceptible to cracking and impact damage. Moreover, the robust, non-ferrite design suits these transmitters for hostile environments.

  • Hoffman Estates, IL, February 28, 2019 - S. Himmelstein and Company announces the upgrade of their Signal Conditioners. The Model 700+ Series Signal Conditioning Instruments are powerful, yet flexible, one or two channel signal conditioners/displays. They feature fast, rock-solid readings, user settable digital filters, real-time cross channel calculations, built-in data acquisition and control functions, serial communications interface, user assignable logic I/O and auto-scaled +5 and/or +10 volt analog outputs.

    Newly enhanced features include:

    • 6 active display digits.
    • 0.001% display resolution.
    • Internal data sampling rate of 7,800/sec.
    • Math channel calculation rate at 7,800/sec.
    • Limit checking performed at 3,900/sec.
    • Serial interface baud rate from 1.2 to 230.4 kBaud.
    • Dual, user selectable analog outputs from 0 to ±10 Vdc or 0 to 20 mA.

    Selecting from 7 available input cards, these instruments can be configured to interface with torque transducers (rotary transformer and slip ring), load cells, pulse output speed pickups and flow meters, voltage output transducers, current output devices, LVDT's, rotary and linear encoders, etc.

    S. Himmelstein and Company has been offering innovative torque measurement solutions since 1960, manufacturing a full line of shaft, spline, flange, pulley, wheel and reaction torquemeters, and other torque measuring instruments.  For more information, call 1-800-632-7873 or visit www.himmelstein.com .


  • Ultra-Precise Digital Torque Sensors
    MCRT® 48800V & 49800V Ultra Precise Shaft torquemeters have analog and digital outputs and the highest accuracy of any similar torque sensor....

  • The ultra-precise MCRT® 48800V and 49800V series digital torque sensors from S. Himmelstein and Company are well-suited for a broad range of applications including both performance and endurance testing of engines, transmissions, drive systems, pumps, motors, servo motors, gearboxes, actuators, etc.

    Each offers extreme measurement accuracy with fast installed response, plus high mechanical overloads and electrical overrange.  Output signals for torque, speed and horsepower are provided as analog (±5 or ±10 Vdc) and digital over RS232 serial port.  Available capacities are from 2.8 to 42,000 Nm.

    They are available in two accuracy grades: ±0.04% and ±0.02% of full scale combined non-linearity and hysteresis, and have world class temperature performance.  Mechanical overloads of 200% or 400% offers a safety margin in the presence of high startup torques or large torsional oscillations such as produced by Diesel engines.  Electrical overrange of 150% avoids clipping of real world torque peaks and driveline torsionals reducing potential for errors in the average torque measurement.  Output bandwidth is 1 kHz with 13 user selectable low pass filters.  

    Null, scaling and units of measure are stored in non-volatile memory. There are no noisy pots or switches. Thirty three units of measure are supported without requiring recalibration. Eleven user selectable Bessel filters avoid delay distortion and overshoot errors. These models incorporate technology hardening them to EMI generated by IGBT based adjustable speed drives. All are calibrated CW and CCW to rated load in our ISO 17025, NVLAP accredited laboratory (NVLAP lab code 200487-0).

  • Ultra-Precise Torque Transfer Standard
    The RTM 2300DV Torque Transfer Standard is ideally suited for accurate field calibration of production torque transducers...

  • Series 2300DV Torque Transfer Standards’ extreme accuracy and simple installation make them ideally suited for nonrotating calibration of production torquemeters. Unlike mV/V output Transfer Standards, use of a mV/V Calibrator isn’t required, thus, its errors are avoided. Multiple bridges and elegant design provide high immunity to clamping and other extraneous loads High Overrange avoids errors from clipped torque peaks. Furthermore, High Overload reduces the likelihood of damage from operator mistakes.

    There are no pots, switches or other parts subject to misadjustment by unauthorized personnel or, from vibration. Bi-directional remote cal verifies operation of the entire data chain in CW and CCW modes. Calibration is invoked via I/O line or from your computer. Hardening against electromag-netic interference generated by Variable Frequency Drives, ISM transmitters and other industrial noise sources further enhances performance. These devices have very high stiffness, low deflection and provide exceptional static and dynamic system response. They are installed without an additional coupling which preserves driveline stiffness, and yields a low overhung moment and a short overall length.

    Included software interfaces with your Windows-based PC. That software displays Real-time, Maximum/Minimum and Spread Torque, can do Torque versus Time plots and store test results. You can select from 11 Bessel Response Filters and 10 Units of Measure without re-calibrating. Password protection may be invoked. Three performance grades are available.
