Digital Indicators
Digital indicators for showing measuring values. The indicators are
designed for panel (IP 22) or local mounting (IP 67). The instruments
come with a pre-printed sheet with the common engineering units.
Features, common
- 4-20 mA loop supplied by measuring signal.
- 3½-digit easily readable LCD display.
- Internal adjustment of zero and range with optional placement of the decimal point.
- For display of measured values of e.g. flow, level, pH and O2.
- Can be used as lid for sensor connection boxes.
- Designated window showing the SI unit used.
- Pre-printed sheet with common SI engineering units supplied.
Features, Local Indicator type 531
- 4-20 mA loop supplied by measuring signal.
- Local mounting in IP 67 housing or separate display insertion for level transmitter junction box.
Features, Panel Indicator type 532
- Panel dimension 48 x 96 mm, panel cutout (1/8 DIN) 43 x 93 mm.
- Display can be back-lit from a separate power source.
