S. Himmelstein and Company has been focused on designing, making and servicing precision torque sensors and signal conditioners since 1960.  We offer the most accurate products with the highest torque overload and electrical overrange and reliability available.  Furthermore, these sensors and state of the art signal conditioners provide Himmelstein users with the fastest, most accurate dynamic response with the highest safety margins.  Reaction and rotating sensors are offered in many styles including bearingless, shaft, flanged, splined, wheel, pulley, C-Face and hollow types.  Performance is proven and documented in our accredited ISO/IEC 17025:2017 Calibration Laboratory.

Himmelstein offers the largest selection of torque ranges, output signals, overload ratings, accuracy grades and mechanical styles, so you’re sure to find the ideal non-contact torque sensors, torque measurement transducers and signal conditioning instruments to suit your needs. All Himmelstein torque sensors and systems are calibrated CW and CCW to their full-scale capacity in our ISO/IEC 17025:2017 accredited laboratory (NVLAP Lab Code 200487-0). With Himmelstein sensors for torque, you enjoy the benefits of our long experience along with the most stringent quality control standards.

How Does a Torque Transducer Work?

All our contactless torque sensors utilize highly accurate, proven and reliable strain gages as the basis for the measurement. The latest, most accurate Himmelstein torquemeters — both rotating and non-rotating (reaction) types — are digitally based. The signal from rotating types is digitized on the rotor and transmitted as digital data to the stator, where analog and frequency (model dependent) signals are created and produced along with digital data. Each torque transducer employs true bi-directional rotor shunt calibration. All signal processing is microprocessor-based; most devices boasting five microprocessors. 

In-line rotating torquemeters with non-contact transfer of signal and excitation voltages, have become the method of choice for most torque and mechanical power measurement applications. Alloy steel sensing elements and built-in high immunity to noise and magnetic fields results in the most accurate and reliable sensors in the industry.

We offer several types of torque transducers to meet your measurement and application needs. For static torque measurement, choose a reaction torque sensor. For dynamic torque, select a rotary sensor. Our inventory offers a broad range of measurement capacities, overload ratings, accuracy classes and more.

Signal Conditioners

Himmelstein Model 700 Series instruments are powerful, yet flexible one- or two-channel signal conditioners/displays. Our transducer instrumentation can be configured to interface with torque transducers, load cells, pulse output speed pickups and flow meters, voltage and current output transducers and more. High quality signal conditioning is a critical component in any sensor based measurement system for processing sensor output signals and providing clean, noise-free test data. Based on our decades of experience with strain gage based sensors, we have optimized our signal conditioning for operation with all types of torque meters and other strain gage transducers.
