Product water

• Degree of protection: IP66/IP68, NEMA Type 4X/6P

Operating frequency

• Frequency: 80 GHz (for measurement purposes only)

Input

• Measured variables include:
  • Level: 0 to 30 m (0 to 98 ft) ±2 mm (0.08 in)
  • Ambient temperature: –20 to +60 °C (–4 to +140 °F) with an accuracy of ± 2 °C (4 °F)
  • Position: Angle of device to the horizontal (Range: 0 to 180°, measurable if sensor does not move)
  • GPS: ±20 m (66 ft) in free field conditions

Output

• Output signal: Cellular radio LTE-M, NB-IoT, GPRS, EDGE
  • Available options depending on order code (030 options A, B, C), supporting various frequency bands for different regions (EU, US, Global).
• Transmission interval: Configurable between 15 minutes and 24 hours. Battery life depends on this setting.
• Protocol: TCP/IP, TLS (v1.2), HTTPS

Power supply

• Type: Replaceable battery, standard size, lithium (D)
• Voltage: 3.6 V
• Capacity: 19 Ah (included in delivery)
• Designation: ER34615 (primary battery lithium thionyl chloride)
• Recommended batteries: Tadiran SL-2880 (Europe), Tadiran TL-4930 (outside Europe). Tadiran SL-2870 (Europe) or Tadiran TL-5930 (outside Europe) are also usable but may affect indicated battery lives.
• Battery Status Indication: Full, medium, low, or critical. LED flashes red every 10 seconds if charge is low or critical.
• Battery Life: Varies significantly based on transmission interval, measuring interval, and GPS usage. Can exceed 8-10 years under specific conditions, or approximately 140-500 days with shorter transmission intervals. GPS operation halves battery life.
• Safety Notice: Do not charge, open, expose to fire or heat above 100 °C (212 °F). Only use ER34615 battery. Dispose of used batteries properly.
