GESTRA LRG 16-9 Conductivity Electrode

The conductivity electrode LRG 16-9 together with the con- ductivity switch LRS 1-.. or conductivity controller LRR 1-.. is designed for measuring and monitoring electrical conductivity in conductive fluids.

If used as conductivity limiter or continuous blowdown con- troller in steam boilers, the conductivity electrode LRG 16-9 can be used with the following equipment:

Conductivity switch LRS 1-7, LRS 1-50,

Conductivity controller LRR 1-50, LRR 1-52

The conductivity electrode LRG 16-9 is used in combination with the following equipment as conductivity limiter and continuous blowdown controller in steam boilers: Conductivity switch LRS 1-7, LRS 1-50,

Conductivity controller LRR 1-50, LRR 1-52.

In addition the equipment can monitor conductivity in con- densate and feedwater systems and in cooling and cleaning water.

The conductivity electrode LRG 16-9 in conjunction with conductivity switch LRS 1-7 is also approved for feedwater monitoring on board of seagoing vessels.

The conductivity electrode works in conjunction with conduc- tivity switches or controllers and monitors the conductivity in conductive fluids.

To measure the fluid temperature a resistance thermometer Pt 100 is integrated in the electrode.

A short circuit or wire breakage in the conductivity electrode will trigger an error message in the conductivity switch or controller.
