Wireless Strain Sensor, Industrial, +/- 2000 micro Strain – Leap Sensors

The Leap Strain Sensor can support all types of strain sensors.  The most common are full-bridge, 1000 ohm, foil strain gages with individual gage factors of 2.0.

Wireless strain sensors typically also include consulting services to assure the sensor is effective in the specific application.  

Most Leap Strain Sensors have some customization to a specific application.

Strain Wireless Sensor

Leap Sensors are specially designed to be customized.  If this isn’t exactly what you need, please contact us.

Application Specific Strain Configuration

This Leap strain sensor comes with the most common range of +/- 2000 u-Strain.  This is the typical range for a foil strain sensor in a long-life application.

Most Leap strain sensors need some customization to a specific application.  Please contact us with details of your application and one of our strain experts will consult with you to make sure the sensor meets the need.

Most strain sensor applications include expert consulting agreements to assure the sensor meets the need.

We recommend using this National Instruments strain sensors guide to designing the optimal strain sensing system.

Strain Sensor Specification

Leap Strain sensors support nearly all types of strain sensors.  The most common type of strain sensor used is a full-bridge foil strains sensor with individual strain sensor gage factors of around 2.0.  Higher resistance gages of 1000 ohms, or greater, are prefered (but not required) to extend battery life.

Balancing resistors can be added to also support half-bridge and quarter bridge configurations.

  • Strain Sensor Range:  typically +/- 2000 u-Strain for a total range of 4000 u-Strain.  The range can be custom configured for a specific application.
  • Strain Sensor Resolution:  <sensor range> / 4000
  • Sensor Typical Accuracy:  <sensor range> / 1000

The Leap wireless strain sensor has shielded cable with 4 wires that attach to a full-bridge strain sensor.  The amplification of the signal inside the electronics module can be adjusted to change the range of strain that the sensor can sense.

The wireless sensor requires that the strain sensor be balanced to zero at zero strain levels.

Leap Wireless Sensor Transmitter Specifications

  • Transmission Distance to a gateway – typically 1500 feet in open air.  Several hundred feet in an industrial environment.
  • Battery Life – 5 to 10 years in typical applications.
    • Different enclosures are available to balance battery size and battery life.
  • Rugged Sensor Enclosure
    • Sealed all-metal enclosure with mounting flanges.  2.44 x 1.33 x 4.73 inches
  • Sensor Mounting Options
    • Screw mount flanges standard.
    • Magnetic mount – optional.
  • High Operating Temperature – Standard sensor -40C to 85C (-40F to 185F).
    • High operating temperature option available: -40C to 125C* (-40F to 260F).  Unique to Leap Sensors.
  • 2-way Communication with the sensor through the user interface:
    • Name the sensor, set sensor sampling time interval, set wireless transmit time interval, over-the-air firmware updates.
    • Gateways send an acknowledgement to the sensor that the data was received for high reliability.
  • Sensor Data Logging – When sensors do not receive an acknowledgement from the gateway that the radio transmission was received, the Leap Sensor will store the time-stamped data on-board until the gateway connection is established.
  • Reliable Industrial Over the Air Radio Communication
    • Industry standard 802.15.4 with Direct Sequence Spread Spectrum (DSSS).
    • Gateway “hand-shake” acknowledgements of successful transmission and sensor data logging for extra reliability.
  • Over the Air Protocol – Standard and established 6LoPan and Thread.
  • Data Security – AES encryption.  Standard and established TLS security.
  • FCC certified.
  • One gateways support 250 sensors that are in-range.  Additional gateways can extend the sensor coverage.
  • Battery – user-replaceable 3.6V battery.

Leap Wireless Sensors Gateway (Receiver) and User Interface Software

See the Leap Sensors gateway products web page and the Leap Sensors User Interface options web page for more detailed information.

Leap Sensors wirelessly transmit their data to a gateway*.  This gateway can support over 250 sensors.  The gateway then passes the data to the Leap user interface software.  The user interface software may be hosted on the gateway (and connected to a PC with a USB cable), on the password-protected Leap Sensors Cloud web site, or an on-site server.

User interface supports: logging-in, set user rights, view sensor data, set email and text alerts (cloud version), graph sensor data, download data to excel, add or subtract sensors, update firmware, and other functions.

*Custom-ordered leap sensors are available with a direct-to-cellular option where no gateway is needed and the data is sent directly to a cloud server.  Contact us for more information.
