Description

Scigiene’s Wireless Gen 2 AC Current Meters measure the RMS current of an alternating current (AC) system using a current transformer (CT) that wraps around the "hot" wire of a two wire (hot, common, ground (optional)) power system. The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and amp hours.  150 Amp available (see related products below).  Scigiene's wireless sensors are ideal for pharmaceutical, medical and other high tech applications where loss of data is unacceptable.  These also have an amazing range of over 1000 ft. with 10 year battery life and can be remotely upgraded via network connections. These are truly the most advanced wireless sensors available.

Features:

  • Wireless range of 1,200+ feet through 12+ walls *
  • Frequency-Hopping Spread Spectrum (FHSS)
  • Improved interference immunity - Improved power management for longer battery life **
  • Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
  • All Gen 2 sensors now have up to 3200 readings: 10-minute heartbeats = 22 days, 2-hour heartbeats = 266 days
  • Over-the-air updates (future proof)

* Actual range may vary depending on environment

** Battery life is determined by sensor reporting frequency and other variables

Operating altitude (non-pressurized environments)

-15.2 to 1,982 m (-50 to 6,500 ft)3

Storage altitude (non-pressurized environments)

-15.2 to 3,048 m (-50 to 10,000 ft)3

Operating humidity

5 to 85% RH (non-condensing)

Certifications

900 MHz sensors: FCC ID: ZTL-G2SC1 and IC: 9794A-G2SC1.

1. CTs are inherently less accurate at or below 10% of max range. For best calibration results calibrate at a current between 30% and 90% of max accurate range.

2. Because of a diode inherent to the hardware, the sensor is incapable of reading between 0 and the deadband value. This diode also creates an offset. To account for this, the firmware uses offset compensation. 3. Operating and storage altitude without DC power supply is -30.48 to 9144 m (-100 to 30000 ft).
