Technické údaje

Alarm: 1 x malfunctioning, 4 x user-configurable, max. 24 VDC/0.5 A, potential free contacts
Analogové výstupy: Active 4 - 20 mA max. 500 Ohm load, standard 1, max. 8 (option)
Certifikace: CE compliant / UL certified
Demineralised water: For rinsing
Digitální výstupy: Optional: Modbus (TCP/IP, RS485)
Doba cyklu : 40 minutes, including oxidation time of 30 minutes.
Remark: standard method for Cr destruction requires 120 minutes.
Earth connection: Dry and clean earth pole with low impedance (< 1 Ohm) using an earth cable of > 2.5 mm²
Hmotnost: 25 kg
Chladící voda: Flow rate approx. 5 L/h; temperature max. 30 °C; pressure max. 0.5 bar
Instrument air: Dry and oil free according to ISA-S7.0.01-1996 quality standard for instrument air
Interference : Chloride > 1 g/L, inorganic reducing agents such as nitrites, sulphides and iron(II) will increase the result, aromatic hydrocarbons and pyridine are not oxidized to any appreciable extent. Some very volatile organic substances may escape the oxidation by evaporation. Straight chain aliphatic compounds are effectively oxidised by the silver sulphate/sulphuric acid solution. Fats, oil, proteins, surfactants and tar.
