Load Cells | Force Sensors | Torque Sensors
Load cells, force sensors and torque transducers can be found in industrial applications around the world, including aerospace, oil & gas, automotive, automation, medical and more. Our load cells provide high-performance and high-reliability, and come in fully welded stainless steel enclosures that measure ranges with high precision from a few grams to 2,000,000 pounds of tension or compression. Using proprietary electronics, these sensors provide low-level (mV/V) and amplified (analog and digital) outputs.
Pancake load cells include high-accuracy, fatigue-rated, precision and coiled tubing injector solution configurations designed for tension and compression force applications. Regularly used in materials test and measurement applications, these load cells include high resistance to shock and vibration inputs.
Canister load cells are designed specifically for high-capacity and high-accuracy test and measurement applications, requiring long fatigue life, combined with high resistance to the effects of extraneous bending and off-axis loading.
Miniature load cells offer a compact size for many tension and compression load applications. These sensors are rugged units, constructed of durable stainless steel, providing reliable performance in demanding conditions while maintaining a small and lightweight appearance.
Subminiature load cells are designed for applications requiring units that are very small and lightweight and fit into the tightest spaces. These sensors are rugged units, constructed of durable all-welded stainless steel, providing reliable performance in demanding conditions.
Rod end load cells are constructed of high strength tool steel. These force sensors are compact in size and provide reliable performance for demanding application conditions. A variety of end connection options are available including tongue, shackle and male and female threaded interfaces.
Thru hole load cells are designed to meet the rigorous performance standards required in harsh environments like oilfield production and feature a center hole for applications requiring a load structure to pass through the load cell. Depending on the force loading arrangement, these force transducers can be used to measure tension or compression.
Beam load cells are high accuracy, low-profile force sensors for both tension and compression applications. These sensors are constructed of stainless steel and provide reliable performance in demanding applications. Additional features include shock and vibration protection.
Clevis pin load cells are ideal for real-time force monitoring of loads and can measure the hanging weight of coiled tubing injectors or tethered ROVs. These sensors are constructed of all-welded stainless steel and hermetically sealed for reliable performance in demanding applications.

Custom Load Cells and Force Sensors
Very few applications offer standard solutions for load cells. Our team of sales and product engineers is available to work with you to find or develop the right force or torque sensor to meet your application requirements, including torque transducers. Provide us a few details and one of our representatives will be in touch.
Selecting the Right Load Cell
Finding the right load cell or torque transducer for your application requires understanding the specific needs and the requirements for the environment in which the sensor will be used. While standard options will normally work well, some applications require custom sensor solutions. These 5 considerations are designed to be at top-of-mind as you search for the right load cell or force sensor for your application.
When looking for a load cell or force sensor to fit your application, it’s important to know the level of performance you need the unit to reach. Does the job require specific conditions or does it need to measure certain weight or load limits?
Here are a few of the questions regarding performance considerations you should be aware of:
- What is the maximum load, weight or force you intend to measure?
- What are the loading conditions of the application - is it tension, compression, both, or multi-axis?
- What type of engineering units do you require? (pound-force, tons, grams, newtons, etc.)
- Are you looking for static accuracy, thermal accuracy or total accuracy (static + thermal)?
- What kind of loading conditions will the sensor encounter?
- Overloading (exceeding maximum load) and by how much?
- Static overload capacity - what safety factors should you take into account?
- Dynamic loading - will it encounter these types, which can exceed anticipated static loads?
- Fatigue loading (high cycle rates)?
- Off-axis loading (side loads)?
- What are the physical requirements?
- Size constraints
- Location access
- What are the configuration specifications - does the application require a certain style?
- What are the mechanical interface requirements?
- Clevis pin
- Tongue shackle
- Load button
- Special configuration
- What is the electrical output from the sensor?
- Is it analog?
- Is it digital?
- Is it a combination of the two?
- What type of electrical termination does it use - does it need additional equipment?
- Connector, integral cable, flying leads
- Mating connectors and cable assemblies
- Connector/cable orientation
- Wiring codes and pin-outs
- What are the external zero and span potentiometers?
- Does your application require DIN rail mount or in-line signal conditioning?
- What is the operating temperature range?
- What is the compensated temperature range?
- What are the EMI/RFI conditions?
- Is an IP or NEMA rating required?
- Will it be housed in a hazardous environment?
- Is it intrinsically safe?
- Is it explosion-proof?
- Will it be used indoors or outdoors? How will it respond to:
- Exposure to the elements
- Dust and dirt
- Extreme temperature
- Animals, critters, rodents, etc.
- Is the sensor submersible?
- Fresh or salt water
- Case pressure
- Does it have any specific calibration requirements?
- Do you need special approvals or certifications?
- What are the requirements regarding testing or cleaning?
- Are there any special labeling requirements?
- What are the frequency response requirements?
- Is it shock- and vibration-resistant?
- What is its serviceability?
- How accessible must the unit be?
- How often will it be serviced?
Keeping all of these considerations under advisement as you begin your product search will ultimately make for a more worthwhile purchase.
