    Why use Hoffmann + Krippner Sensofoil membrane potentiometers? They enable your product’s full potential with precision accuracy and nearly endless customizability.

    Cost advantages

    In general, a membrane potentiometer up to 700 mm in length presents a cost-effective option in place of traditional potentiometers: relatively inexpensive to manufacture, even with custom designs, they can be conveniently integrated in new and existing applications.

    Perfect fit for almost any application

    With Sensofoil®, Hoffmann + Krippner offers a fully customizable position sensor with almost limitless dimensions in length and radius, thanks to the flat and layered composition. In fact, almost any customer requirement can be fulfilled. Our industry-leading Sensofoil® team will guide you through the customization and implementation process.

    Durability and long service life

    Flat, durable, and sealed, Sensofoil® membrane potentiometers enjoy a service life between 1 million to 20 million operations. Depending on the model selected, they can even work in dirty, unstable, and/or hot environments. Integration in control units allows for fully sealed surfaces according to IP65. As an analogue sensor, the position signal is readily available even after a power outage. This eliminates the need for an otherwise potentially critical reset feature.

  • Updated web presence for load cells and force sensors

    Hoffmann + Krippner, Inc. proudly announces that some of the most reliable load cells and force sensorsmanufactured by Inelta are now part of their US product portfolio! Force sensors from Hoffmann + Krippner partner Inelta can measure loads with unparalleled accuracy, reliability and flexibility. They have specifically been developed for measuring static and dynamic forces in all industrial sectors, including mechanical engineering, automation engineering and laboratory and medical technology. The strain gage is protected by a steel or aluminum housing and is thus suited for use in rough and demanding environments.

    Easily accessible product information for each product category allows the customer to spend less time searching and get right into implementing the perfect load cell and force sensor solutions into their applications.

    Datasheets, list of specifications, product news, blog posts showcasing various types of applications as well as our engineering team are all important tools available to our customers.

    Feel free to browse through the following product categories:

    • Button load cells: measuring pressure either from one or two directions
    • In-line load cells: measuring without direct contact by attaching to an intermediate object
    • Pancake load cells: measuring push / pull or compression / tension connecting at multiple locations with rods going through the center or other points
    • S-beam load cells: appropriate for heavy-duty loads such as industrial cranes, containers, trains, etc.

    Please contact us if you need assistance in selecting the perfect load cell solution for your application.

  • What is Sensofoil®?

    In our last blog post, we answered the question, “What is a membrane potentiometer?” Today, we’re going to talk about Sensofoil®, the Hoffmann + Krippner brand of membrane potentiometers, and how it differs from others.

    The name gives you the first clue of how Sensofoil® membrane potentiometers stand out. In addition to using them as normal potentiometers (i.e., as set-point generators in input devices like hand-held controls), they can also be used flexibly as highly accurate and reliable linear and rotary position sensors. The ultra-thin design means they fit seamlessly into restricted installation conditions.

    Sensofoil® refers to a family of membrane potentiometers. The flagship PET-PET model uses conductive ink printed onto flexible PET foils (hence the “foil” part of the name), including a resistive track on the bottom foil and a top foil that works as a tap. This construction offers an excellent life span. This foil-on-foil design can also be fully enclosed with an IP rating up to IP65.

    In addition, the Sensofoil® family also includes alternative designs to work within a wide variety of applications and conditions.

    For example, one version can be printed directly onto FR4, if the customer has an application where they’d attach the membrane potentiometer to the enclosure with screws rather than an adhesive backing. For applications at particularly high temperatures – as in automotive, aerospace, and industrial settings – the Sensofoil® family also includes a PET-Hybrid formulation that can operate at more extreme temperatures of up to +85°C. Altogether, the Sensofoil® family includes the following lines:

    Sensofoil® PET-PET A durable, ultra-thin design that works within a wide temperature range
    Sensofoil® PET Hybrid Particularly resistant design that works with high temperatures
    Sensofoil® PET Magnet Contactless design with an especially long-life span
    Sensofoil® FR4-PET Flat design with various connection options
    Sensofoil® FR4 Hybrid Particularly resistant design that works at the greatest temperature range
    Sensofoil® FR4 Magnet Contactless design that works especially well with electronic equipment

    Operation is identical with all forms of the Sensofoil® membrane potentiometer. With a finger or wiper, pressure is applied to the collector membrane, causing contact between the metal strip and base membrane. The resultant voltage is proportional to the distance, angle, or position being measured.

    Sensofoil® potentiometers can be easily customized to required length, angles, and resistance values, so that they can be adapted to fit perfectly into existing applications.
