A complete solution for DEPU tubular steam trace heaters is provided by temperature control, limitation and power setpoint adjustment, all in one unit. DEPU is ATEX-certified and approved for use in potentially explosive areas.Structure
All functional units are integrated in a standard casing of aluminium. The connecting lines up to 6 mm? are contacted with cage tension spring clamps.Function
The controller is designed as a two point controller and measures the temperature by means of a Pt 100. The limiter works as an independent system and measures the temperature at the hot spot with ist own Pt 100. If the temperature exceeds the limit value the limiter interrupts the heater permanently and a fault signal is given. All fault alarms are indicated by a master fault contact. Resetting can be carried out directly on the unit or externally with a key. The power setpoint adjuster works as a fault-free full wave control by means of a semi-conductor relay. A 7-segment display guarantees good readability of the temperature values of controller and limiter through the viewing plate.Tehnilised andmed (väljavõte)
