ARCUS-EDS 91110020 Measuring probes for SK08-WAQ

The ARCUS-EDS 91110020 product is a measurement sensor specifically designed for the SK08-WAQ system, used for measuring and controlling the chemical and physical parameters of water.

Key Features

This sensor is equipped with a single-stylus measuring cell for measuring pH and oxidation-reduction potential (ORP).

Measurement Range

• pH: 0.1.3
• GOLD: 0.. 1200 mV
• Water temperature: -20.. 100°C

Operating and Storage Temperature

• Transducer operating temperature: -20.. +55°C
• Transducer storage temperature: -20.. +85°C

System Functionality

The sensor includes a high impedance isolated measurement amplifier (> 500 GΩ) with BNC connectors. The inputs for the signal are between -600.. 600 mV for pH and 0.. 1200 mV for ORP.

Control and Alarms

• Two-position controller with 1-bit switched and pulsed output for pH and ORP
• PI controller with 8-bit static or 1-bit modulated pulse width output for pH and ORP
• Periodic display of measured values or when the value changes
• Periodic parameterized sending of control variables
• Parameterisable release and lock function
• Threshold alarms for higher and lower values

Calibration and Accessory Functions

• Sensor calibration (1 point and 2 points)
• Restoring factory settings
• Operating time counter with threshold and reset
• Additional inputs for a temperature sensor and two dry contacts

Protection and Construction

The transducer case is protected with an IP54/65 degree of protection, ensuring robustness and durability even in severe environments.
