Ex amplifier for level controllers in zone 1

Gettorf - SF3 amplifiers for EGE level controllers are suitable for explosive gas atmospheres: they provide protection according to II (1) 2 G EEx em [ia/ib] IIC T6 and can be installed in zone 1.

Gettorf – SF3 amplifiers for EGE level controllers are suitable for explosive gas atmospheres: they provide protection according to II (1) 2 G EEx em [ia/ib] IIC T6 and can be installed in zone 1. Therefore, they allow for deployment close to sensors, e.g. in immediate proximity to fuel tanks. For monitoring fill levels in such applications, EGE provides the Ex level controller series URFS and thermal sensors featuring a 160 Ω resistance. The amplifier units are designed for temperatures between -20 and +60 °C and are IP 54 protected. A relay serves as a switching output, e.g. to switch  a solenoid valve. The lines can be installed with "increased safety" or "intrinsic safety" type protection.
