Wireless CT Unit monitoring up to 3 Current Transducer (CT) Sensors

 

The Wireless CT unit monitors up to 3 Current Transducer (CT) Sensors and wirelessly transmits data via EnOcean.

The Wireless CT unit is easy to install and can connect up to 3 standard Current Transducers (CT) input via RJ12 sockets which is supplied as a 63A version (200A available or customer can supply), because the unit is inductively powered, no maintenance is required.

Current transducers combine a current transformer with a signal conditioner into a single package for current monitoring or logging applications

Features, Benefits & Functions

  • Easy to install
  • Option for either EnOcean or Bluetooth protocol.
  • Compact design
  • Measures every 1 second
  • Frequency of transmissions can be adjusted to 1/5/20/30/60 Seconds

The Wireless CT unit is easy to install and can connect up to 3 standard Current Transducers (CT) input via RJ12 sockets using a 1 metre length sensor lead, which is supplied as a 63A version (200A available or customer can supply), because the unit is inductively powered, no maintenance is required. The current is measured every second and an average taken (with an accuracy of 2% full scale) which can then be transmitted every few seconds depending on requirements.

 

Range

The signal strength between the transmitter and the receiver decreases as the distance increases. Where there is a line of sight connection, the range is approximately 30 m in corridors and 100 m in large workshops or halls. The range can be increased with a MobiusFlow EnOcean connector.  

  • Masonry    20m, through 3 walls at most
  • Reinforced concrete  10m, through 1 wall / ceiling at most
  • Plasterboard / Wood  30m, through 5 walls at most

EnOcean

Self-powered Internet of Things. EnOcean stands for energy harvesting wireless technology, which enables maintenance-free sensor solutions delivering data for intelligent networks in buildings and the Internet of Things.  

Energy Harvesting 

wireless sensors harvest and manage the smallest amount of energy from their environment.  

Wireless 

EnOcean uses wireless standards optimised for solutions with ultra-low power consumption and energy harvesting.  

Ultra-low Power 

Energy management and highly efficient energy storage are key to wireless technology for battery-less wireless sensor solutions.

 

MAC address via NFC 

The Wireless Current Interface Unit has a NFC transmitter to enable MAC address identification via any NFC reader. Please note this is located on the middle bottom (opposite side to C.T sockets) and the range is typically near touch (5 15mm maximum between WCIU and reader).
