2-Wire, 4-20 mA Loop Powered Torque Transmitters-39000X

• Enhanced Performance (code C )
• Foot mount (code F)
• Magnetic Speed Pickup (code Z)
• Explosion-Proof Speed Pickup (Code P)

When installed between a driver and its load, MCRT® 39000X torque transmitters measure bidirectional static (stall) and dynamic shaft torque and speed (an option). These devices use proprietary Himmelstein technology field-proven in four decades of use. A one piece stainless shaft carries bonded, foil strain gages. They measure torque, and in combination with element design, cancel bending and thrust loads. Rotary transformers connect the rotating gages to stationary, 4-20 mA transmitter circuitry. The transformers provide high quality non-contact signal coupling to the rotating gages. Rotary transformers don't wear or generate noise. They are immune to ambient noise, vibration, lubricants and other hostile environments.

MCRT devices provide the fastest, easiest, most ® dependable way to measure torque. The use of actual rather than inferred torque, mechanical power and energy makes possible otherwise unusable processes and machine control strategies. Control and verification of machine performance, efficiency, load, load sharing and detection of dangerous and wasteful conditions are valuable benefits. Examples are process and machine degradation, overload, load loss, and destructive torsionals.

MCRT 39000X’s incorporate new technology that ® harden them to the intense EMI generated by IGBTbased, adjustable speed drives. These devices have ten times the immunity of earlier 4-20 mA, loop powered torque transmitters. Transmitter Description When installed between a driver and its load, MCRT® 39000X torque transmitters measure bidirectional static (stall) and dynamic shaft torque and speed (an option).

The transformers provide high quality non-contact signal coupling to the rotating gages. Rotary transformers don't wear or generate noise. They are immune to ambient noise, vibration, lubricants and other hostile environments. RFI shielding and the current output, provide high noise immunity. NIST traceable field adjustments are free of cable effects. There are no slip rings, brushes, radio transmitters and other noisy, limited-life elements. Unlike ferrite transformers, Himmelstein ferrite-free units aren’t susceptible to cracking and impact damage. Moreover, the robust, non-ferrite design suits these transmitters for diesel and other hostile environments.
