Thermowell Specification

  • Probe
    • PT100, 3 wire, Class A w[0.15 +0.002 |t|] °C
    • Sensing Range: -50 to 300°C, (-58 to 572°F)
    • Response Time: 7 seconds, 63% of a 25 to 77°C step change (ASTM E1137)
    • RTD element encased in alumina powder insulation provides excellent vibration dampening and heat transfer
    • Stainless steel probe
  • Connection Head
    • Cast aluminum NEMA 4X, IP66 screw cover head with captive gasket
    • One turn cover removal & installation eliminates cross threading and saves time
    • 3/4 NPT conduit opening with internal stop to prevent over- tightening and installation damage
    • Gripping ribs on cover edge
    • Stainless steel cover chain
  • Wiring
    • Ceramic terminal base
    • Brass terminals with stainless steel screws eliminate the need to wrap connections around screws
    • Elevated terminal block for easy wire termination

The Leap wireless sensor electronics can be integrated with a wide range of  PT100 3-wire thermowells.

Leap Wireless Sensor Transceiver Node Specifications

  • Transmission distance to gateway: typically 1500 feet in open air. Several hundred feet in an industrial environment.
  • Battery
  • Rugged sensor enclosure
    • IP68 enclosure rated to 120C. 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.
  • 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 or M5 panel connector and cable: Molded M8 or M5 cable connects 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.
    • Bi-color LEDs integrated into the power switch blink to provide user feedback on sensor functions.
  • Long-range antenna inside the enclosure: Keeps the total footprint small and prevents damage to the antenna.
  • 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 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.
