Chicago-based S. Himmelstein’s MCRT 39000X devices accurately measure torque for control and verification of loads on oil rig support legs, the company says.
The MCRT 39000X enables load monitoring during jacking operations and helps maintain stability on uneven or 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. 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.
The MCRT 39000X has high immunity to noise interference, high safety margins, and maintenance-free design. It has been ceritified 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.
