AT/ATR-FD series features include:
- 4-20mA analogue signal proportional to AC current
- available in both average responding and True RMS models
- simple and reliable 2-wire loop powered connection
- choice of 0-200, 300 or 400A
- factory calibrated with 5-year warranty
- DIN rail or panel mount
The AT/ATR-FD series is ideal for applications such as:
- monitoring large machines: detect over/under-current conditions before breakdowns occur
- water delivery/treatment: detect open discharge lines, locate clogged filters and blocked intake to pumps, and measure increased current to show failing bearings or pump impeller cavitation
- generators: shed noncritical loads when demand reaches set level
