> LLB250

A tiny powerhouse with high frequency response

LLB250 is a Miniature Load Button in a class of its own. Capable of measuring compression forces up to 250lb with a footprint of just 0.5in (12.7mm) diameter and 0.15in (3.9mm) in height, it is an extraordinarily powerful and precise miniature sensor. It features a custom strain element for robust integration with the sensor case, as well as internally embedded zero balance and thermal compensation, allowing for outstanding sensor reliability, accuracy, and performance. The single-gauge design completely eliminates inter-gauge wiring, leading to enhanced calibration performance.

The diverse and durable LLB250 sensor is designed for press or inline compression applications, such as measuring loads on a turbine shaft or gauging forces on a CNC workpiece. The sensor has a highly flexible 34 AWG, 4-conductor, 5-foot (1.5 m) long braided shielded cable. This model can also be modified to suit OEM applications. FUTEK offers application and engineering resources during DFM/DFX stage upon request.

  • Diameter: 12.7mm
  • Height: 3.9mm
  • Capacity: 100 to 250lb

Range and flexibility

LLB250 series offers load buttons in two capacity options that measure compressive loads from 100 to 250lb (45.35 to 113.4kg). Its highly flexible mounting options include securement from the outer lip, retention with screws, or mounting inside a counterbore hold.

Made to be accurate

The LLB250 delivers a highly accurate performance with a deflection of 0.0005in nom and nonlinearity starting at 0.5%. The spherical radius of the load button has been designed to maintain the highest possible level of accuracy. By minimizing contact with the loading provisions, the button’s spherical shape transfers the load evenly over the sensing area, compensating for potential misalignments.

LCM300

High natural frequency

The LLB250 delivers a remarkably high natural frequency (starting at 33.0kHz and going up to 41.7kHz) which provides a fast response time that benefits accuracy and cycle time reduction in dynamic applications. The precision of the sensor is also augmented by its high stiffness, which leads to a very low deflection of 0.0005in (0.013mm). In addition, special design and manufacturing touches further enhance the sensor’s performance, such as a highly customized strain element.

LCM300

Robust construction

The aerospace-grade stainless steel body provides outstanding strength and corrosion resistance and provides enhanced protection against physical damage in addition to withstanding other harsh environmental conditions. A special heat treatment process has been applied to the flexure to improve durability, extending the life-cycle of the sensor.

Integrated temp compensation

The sensor is fully internally temperature compensated, and no external conditioning circuitry is required, which increases accuracy without increasing the cost. It also offers flexibility for cable routing and customization of the cable length.

Best-in-class material

The exceptional quality of this sensor makes it highly durable and reliable. Its body is made of aerospace-grade 17-4 precipitation hardened stainless steel, which provides high strength, high hardness, and corrosion resistance over a wide temperature range.

Flexible cable

The sensor cable is a highly flexible 34 AWG, 4-conductor, 5-foot (1.5m) long braided shielded cable that bends easily within a very tight radius. A braided shield physically covers the signal wires while significantly reducing interference from stray magnetic and static electric fields. Although extremely flexible, the cable is not intended for high flex cycles.

Reducing error

A highly customized strain element has been designed to allow more strain measurement around the active sensor element, which reduces reproducibility errors from off-axis loads. It also makes the sensor less sensitive to installation mishaps.

Moisture resistant

With an IP64 rating, the product is dustproof and can withstand splashing water from any direction. This opens up more options for applications in humid conditions.

Calibration included

The LLB250 has been tested by FUTEK’s world-class calibration department and is NIST traceable. We can also reduce hidden costs and setup time by calibrating your sensor with FUTEK electronics of your choice. In addition, we offer calibration to ANSI Z540-1 and ISO 17025 standards upon request.

Made in California

Designed and manufactured in-house, using US-sourced materials. Our multidisciplinary engineering teams, high precision machining center, state-of-the-art quality assurance systems, and R&D and manufacturing facilities are all under one roof, allowing us to continuously reinvent and refine our products and processes.
