Wireless Load Cell Sensor, Full Bridge – Leap Sensors

Leap Sensors are specially designed to easily adapt to your specific needs. If this isn’t exactly what you need, please contact us.

See a demonstration of the Leap wireless load cell and strain sensor below.

Wireless Load Cell Sensor Specifications

• The Leap wireless sensor electronics can be integrated with a wide range of load cells:
  • Standard product integrates with a full bridge load cell and Open CAN.
  • 120 ohm, 350 ohm, and 1000 ohm.
  • Gage factor (2.0) standard.  Other gage factors also available.
• Most wireless load cells are tailored to specific needs.  Contact us to integrate an application-specific load cell with the Leap Sensors wireless system.
• Over-the-air wireless zeroing.

Leap Wireless Sensor Transceiver Node Specifications

• Transmission distance to gateway: typically 1500 feet in open air. Several hundred feet in an industrial environment.
• Battery
  • Field replaceable off-the-shelf Tadiran  TL-5930/F 3.6V battery with tethered connector – designed for high vibration industrial environments.
  • Typical battery life of at least 5 to 8 years. Replaceable in less than a minute.
• Bi-color LEDs integrated into the power switch blink to provide user feedback on sensor functions.
• Rugged sensor enclosure
  • IP68 enclosure rated to 120C (248F). Panel connectors and glands rated to IP68. Power switch with LEDs rated to IP66.
  • Rugged polycarbonate composite enclosure. UL 94 V0 rated, flame-resistant and self-extinguishing.
  • 4.4 x 3.2 x 3.4 in  (113 x 80 x 90 mm), not including optional mounting feet.
• Long-range antenna inside the enclosure: Keeps the total footprint small and prevents damage to the antenna.
• Mounting options
  • See all enclosure mounting options.
  • Optional mounting feet may be installed horizontally or vertically.
  • Enclosure may also be mounted with screws directly to surface.
  • Magnetic mount option.
• Cable connection options
  • Standard: Metal IP68 cable glands seal cables to the enclosure. Industrial spring terminal blocks connect the cable to sensor board.
  • Optional: M8 panel connector and cable: Molded M8 cable connects M8 panel connector to sensor.
    • Cable length may be shortened in the field if desired.
  • More information here.
• Industrial power switch: Latching push button. IP66 rated.
• 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 (device), set sensor sampling time interval, set wireless transmit time interval, over-the-air firmware updates.
  • Gateways send an acknowledgement to the device 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 sensor will store the time-stamped data on-board (up to 10,000 readings) 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 “handshake” acknowledgement of successful transmission and sensor data logging for extra reliability.
• Over-the-air protocol: Standard and established 6LoPan and Thread.
• Data security: “gold standard” internet security with AES encryption.
• FCC certified.

Leap Wireless Sensors Gateway (Receiver) and User Interface Software

• See the Leap Sensors gateway page and the Leap Sensors User Interface options page for more detailed information.
• Leap Sensors wirelessly transmit data to a gateway*.
  • Gateway can support over 250 sensors that are in range. (Additional gateways can extend sensor coverage.)
  • 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.
