Measure principle

Optical measure by luminescence

Measure ranges

Limit of quantification

2.2%

Repeatability (100% Sat)

0.2%

Linearity

>0.99

Response time

0 -> 100%; T90 < 40s / 100 -> 0%; T90 < 65s

0°C to 50°C

Temperature accuracy

+/- 0,5°C

Signal interface

Modbus RS-485 or SDI-12 — 1,2: The sensor responds in Modbus / SDI12 including during Standby; 3: The use and connexion of SDI12 bus may increase the standby power consumption* up to 100uA depending the level of the line (high or low). The consumption is not increased if the SDI12 line is disconnected or released to 0V (Modbus RTU only)

Sensor power-supply (RS485 and SDI12)

5V to 12V DC (warm-up time 100 ms) — 1: Absolute minimum 4.5V with 1m of cable, boot and precision not guaranteed under 5V; 2: Minimum voltage subjected to cable length-related losses; 3: 13V Absolute maximum with a more than 2mA continuous over consumption; 4: Small overconsumption between 12V and 12.5V

Consumption

Standby: 25 µA / Average RS485 (1 meas/s): 3.2 mA / Average SDI12 (1 meas/s): 6 mA / Current pulse: 85 mA (3 mS) — For more details, refer to the user manual
