N21, Panel Meter with OLED Graphic Display for Temperature and Standard Signals
N21, Panel Meter with OLED Graphic Display for Temperature and Standard SignalsThe panel mounted N21 meter from LUMEL is a programmable panel mieter for measuring DC voltage and current standard signals or temperature using type K or type J thermocouple sensors or a resistive Pt100 temperature sensor.
The bargraph and numerical display is performed via an OLED display with 32 x 128 pixels.
The N21 is available in two versions for vertical or horizontal mounting (please select when ordering!).
The free eCon software is used to configure the meter. For this it needs to be connected to a computer via the mini USB interface.
- The following parameters can be programmed:
- Decimal point
- Working mode of the relay output
- Threshold of triggering the relay output
- Delay in triggering the relay output
- Individual characteristic
- Automatic or manual cold junction compensation for thermocouples
- Averaging time
- Custom display unit
- Choice of message language
- Configuration of the bar graph
The output signals are galvanically isolated from the input signals and the supply voltage.
