    Compression Force Sensors for Tight Spaces

    Thinner than a credit card, these force sensors fit into narrow spaces to measure the applied load between two surfaces. While they’re less accurate than larger alternatives such as load cells and handheld force gauges, these will fit almost anywhere. Place them within an industrial press to make sure it’s operating in a safe range, or form them to the contour of a forklift seat to test the concept of adding a smart switch that detects when an operator is sitting and ready to operate the forklift. Sensors should be calibrated before first use. Also known as force sensing resistors.

    2-Pin Sensor Connection and 3-Pin Sensor Connection—To connect 3-pin and 2-pin sensors into hubs with USB connections, adapters (sold separately) are required
    USB-A—Kits with USB-A connection include a hub that plugs into your computer’s USB port.
    Wi-Fi—Kits with Wi-Fi connection use a hub that wirelessly connects to a computer or tablet within a sensing distance of 210 feet. The hub’s transmitter is certified 802.11b radio – 802.11b/g/n to meet IEEE standards for compatibility with other devices.

    Expand your connection kit with additional sensors. Using more than one sensor allows you to monitor pressure at multiple points across a machine. Each sensor requires its own hub. Track changes in resistance by adding a multimeter, or use the data recording software included in our kits (sold separately).
    Additional sensors and hubs expand the connections kits.
