Torque Transducers in the Oil and Gas Industry

Helping to Ensure Accuracy in Oil and Gas Applications

S. Himmelstein and Company offers several inline rotating torque measurement products well suited for use in the oil and gas marketplace, including performance testing of mud pumps, optimization of electric motors, measurement of top drive torque, monitoring pinion gear torque on jack-up vessels and more.

A line of high-capacity square drive as well as hollow-flanged torque sensors is appropriate for the calibration of make-and-break machines. All sensors are provided with ISO 17025 accredited calibration certificates.

Jack-Up Rig Torque Transmitters Monitor Leg Loads

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 with 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.

Square Drive Reaction Torque Transducers

To verify the amount of rotational torque applied by heavy power tools, for example, these stationary (non-rotating) transducers permit accurate confirmation of static and dynamic torque. The RTM 2208 and 2209 transducers can be used while the device under test may be rotating, such as when calibrating torque wrenches used in make-up and breakout of drill strings in oilfield applications.

These transducers carry capacities from 25,000 to 325,000 lbf-ft and offer a compact mechanical package and cost-effective alternative to rotating torque transducers, which have a much higher cost and more complex installation.

In applications such as determining the torque required to open/close large valves, these Himmelstein square drive reaction torque transducers are characterized by high torsional stiffness, very high overload and high extraneous load capacity. Their low weight and compact size simplify installation and handling. All models are calibrated CW and CCW to rated load in our NVLAP-accredited laboratory, (NVLAP Lab Code 200487-0).
