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).
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.
*NIST traceable calibration performed in our accredited lab (NVLAP Lab Code 200487-0).

Benefits
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.
Torque Transmitter Construction
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.
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.

Shaft End and Flanged Models
Shaft end transmitters are the choice for most
applications. They cost less than flanged models and, they
can either be floated or foot mounted. Flanged
transmitters are much shorter than the shaft end types.
Therefore, flanged models are often used when axial space
is insufficient to accommodate a longer, shaft end model.
General Specifications
Flanged models also handle large* axial or thrust loads
without special mounting considerations or hardware. As
a result, they are frequently used in marine or vehicular
drives, to support the weight and thrust of a mixers'
impeller, and in other similar circumstances. A flanged
transmitter must be installed as a floating shaft.
* generally a thrust in pounds equal to the transmitters' full scale rating in pound-inches.

Not available in 25 lbf-in range.
Bandwidth upper limit is determined by the transmitter filter(s). The self
resonant frequency of its mechanical element is greater than 1 kHz.
CW torque causes the transmitter shaft to turn CW when viewed from its
driven end. CCW torque causes the opposite rotation.
"F.S." denotes "full scale". "rdg." denotes "reading". "deg. F." denotes
"degree Fahrenheit".
Speed ratings are for continuous, bidirectional operation.
These transmitters will operate in a condensing atmosphere, and if wetted
with non-corrosive fluids and mud. When used under contaminated
conditions, clean regularly or cover to deflect contaminants. These devices
are not submersible.
Transmitters operated in hazardous locations must be purged with air or
another inert gas. Provision is made for porting purge air via the standard
conduit fitting. When measuring speed in a hazardous atmosphere, specify
an explosion proof speed pick-up (Code P).
Construction materials are: Flanged models use stainless steel shaft &
flanges, Shaft models use nickel plated alloy steel shafts and stainless steel
end bells. Bodies are low copper aluminum. Electronic housings are cast
iron painted with epoxy polyester. Bolts are 316 stainless steel or black
oxide alloy steel.
Electrical connections are screw terminals for loop connections via ½"
internally threaded conduit fitting. Optional zero velocity pick-up uses an
MS connector. Optional explosion proof speed pick-up has wire leads and
a ½" internally threaded fitting.
Specifications and dimensions are subject to change without notice.

Installation
When it's installed between a driver and its load, a transmitter measures shaft torque. A shaft end transmitter may be
floated or, foot mounted as shown in the upper sketch.
Both shaft end and flanged end types may be operated as
floating shafts; see the lower illustration. A floating transmitter handles the greatest axial loads, a foot mounted
transmitter operates at the highest speeds.
Just connect loop power as shown. A voltage between 10
and 28 volts dc is required. Switches select the desired
operating mode, i.e., CW or CCW, unidirectional or
bidirectional. A switch also selects a 1 or 200 hertz frequency response. The 1 hertz cutoff is useful for eliminating
vibratory signals, if present. The 200 hertz response may be
used to drive a fast controller or for wideband data acquisition. Internal, NIST traceable, calibration circuitry verifies
transmitter operation and simplifies scaling of the customers' recording/control system.

Available Options: Available options are listed. Consult the factory should you have special requirements.
Enhanced Performance - Code C, or N if Standard
Zero Velocity Speed Pick-up - Code Z, or N if None
This option reduces measurement errors by a factor of two or more. See
specifications for full details.
Outputs 60 voltage pulses/revolution, not 4-20 mA. Its amplitude is
constant with speed. It requires 5 to 15V dc power. Output pulse amplitude
is approximately the input supply voltage less 0.5 volts.
Foot Mount - Code F, or N if None
Foot mounts provide a rigid stator mounting. They are only available on
shaft end transmitters. Refer to outline drawing for dimensions.
Order No.
Explosion-Proof Speed Pick-up - Code P, or N if None
Outputs 60 voltage pulses/revolution, not 4-20 mA. Its amplitude is proportional to speed. Use Code Z pick-ups for speeds below 500 rpm.
