Conductivity Controller

GESTRA LRR 1-60 Conductivity Controller

The LRR 1-60 conductivity controller can be used in conjunc- tion with LRG 16-60, LRG 16-61 and LRG 17-60 conductivity electrodes as a conductivity controller in pressurised steam and hot-water plants and in condensate and feedwater tanks.

The equipment is configured and operated and information is viewed via the URB 60 visual display and operating unit.

The LRR 1-60 conductivity controller is a 3-position step- ping controller. It cyclically evaluates the data telegrams from a conductivity electrode (e.g. LRG 16-60, LRG 16-61 or LRG 17-60).

The data are transferred to an ISO 11898 CAN bus via the CANopen protocol.

Function tests and failure diagnosis are performed using the URB 60 visual display and operating unit.

Possible combinations of functions and equipment

Conductivity controller LRR 1-60

Function
Evaluation of CAN bus data telegrams from connected LRG 16-60, LRG 16-61 or

LRG 17-60 conductivity electrodes.

 

3-position stepping controller with propor- tional plus integral control (PI controller) and actuation of an electrically operated continuous blowdown valve.  

MAX alarm when the conductivity limit is exceeded.  

MIN alarm when conductivity drops below the minimum limit.

Alternatively
