Level Relay RU-305

RU-305 is intended to control the liquid level in the open tanks and closed tanks under pressure. RU-305 switches the electric circuits when the liquid level reaches the pre-set value.

The relay is equipped with explosion protection, having the explosion safety "Explosion-proof casing".

Controlled environment parameters:

• Density - from 650 to 3000 kg/m³;

• Pressure - up to 20 kgs/cm²;
• Temperature - from -50 to +100°C;
• No hard inclusions;

Performance:

• The operation error in normal operation conditions is max ±5.0 mm;
• Output signal - open/close dry contacts;
• Load - active, inductive.
• Voltage - 220 (+10/-15) V.
• Current - max 1.0 A.
• Weight - max 5.5 kg.
