48200V TORQUEMETERS measure and output
shaft torque and speed; speed is an option. Manual adjust-
ments and noisy pots are eliminated.
Null, scaling and
unit of measure are stored in non-volatile memory. Ten
common units of torque are supported. Bessel response
signal filters avoid delay distortion and overshoot and
assure optimal measurement response. You may choose
from eleven (11) filter cutoff frequencies; 0.1 to 200 Hertz
in 1-2-5 steps. Input power is a single, unregulated dc
supply. The torquemeter has reverse polarity protection.
If you re-calibrate, previous calibration values are
archived. Pin strapping and serial commands enable
traceable* torque calibrations, and remote zeroing. Pass-
word protection may be invoked if needed.
* NIST traceable calibration performed in our accredited Cal Lab
(NVLAP LAB Code 200487-0). For details visit www.himmelstein.com or
www.nist.gov.
Torque is sensed by one or more metal foil strain gage
bridges. The rotating bridges are excited, amplified and
converted by proprietary circuitry which produces coded
data unaffected by amplitude variations. That data is then
transmitted to the stator as infrared (IR) energy where it
is detected and output in industry standard analog and
digital formats.
The IR transmission is inherently tolerant of electrical
and magnetic noise. Because MCRT
®
48200Vs are fully
enclosed, they are immune to sunlight and virtually all
airborne contaminants. Power is transferred to the rotor
inductively, without contact. Elimination of slip rings,
brushes, radio transmitters and other limited-life, noise-
generating and noise susceptible elements provides long
life and high data reliability.
