FAQ

What level switch is the NRG 16-11 compatible with?

The NRG 16-11 is designed to work with GESTRA level switches, such as the NRS 1-40, NRS 1-41, and NRS 1-50 series. Always check the specific controller’s documentation for compatibility.

What is the minimum required conductivity of the fluid for this electrode to function correctly?

This electrode is designed for conductive liquids. The switching points are specified for conductivities of c = 0.3 cm-1 and c = 0.13 cm-1. It is suitable for typical boiler feedwater and condensate.

Can the probe length of 85 mm be shortened or extended for a specific application?

No, the probe length is factory-set and should not be modified. Altering the length can affect its performance and safety certifications. A different model with the correct length should be ordered if needed.
