Knick Indicators
Whoever wants to monitor and control processes, must detect different process variables. The measurements are usually carried out in a wide variety of environments with significant fluctuations in temperature and humidity, in aggressive, explosive atmospheres, or with strong vibrations.
The high-precision universal digital indicators from Knick require no external power source and are perfectly suited for use under difficult conditions – e.g. in hazardous areas.
Loop-Powered Digital Indicators in Panel-Mount Housing
Loop-powered digital indicators, character height 16 to 23 mm, for 0(4)…20 mA loops.
Loop-Powered Digital Indicators in Panel-Mount Housing
Digital loop-powered 830 series indicators are universally usable in current measurement circuits; switching (either 0 … 20 mA or 4 … 20 mA) is simply performed via the terminals. The measured value is displayed for a current as low as 0.3 mA. Thanks to the low voltage drop of just 0.5 V, the use in current loops with a low load voltage is also possible.
- Digital indicator without power supply or power cables
- No signal interference from power supply coupling
- Indicator not affected by grid outage
- No parasitic voltages
- Universal range adjustment
- Selectable unit symbols
- Freely configurable, floating min/max switched outputs, optional
