GESTRA LRR 1-52 / LRR 1-53 / URB 50

Description

As an option, controllers from the LRR 1-52 and LRR 1-53 series can operate in conjunction with a simple conductivity electrode and separate temperature sensor, or a conductivity transmitter from the SPECTORcompact line. They are operated using the separate URB 50 touch panel. Here, trend values, error messages and limit values are displayed in addition to set points and actual values.

The controllers have been optimised for operation with BAE continuous blowdown valves. All units feature an actual-value current output as standard, and offer a blowdown timer and standby input.

Tecnical description

The functional unit consisting of the operating & display unit URB 50 / conductivity controller LRR 1-52, LRR 1-53 in conjunction with conductivity electrodes LRG 1.-.. and conductivity transmitter LRGT 1.-.. is used as conductivity controller and limiter, for instance in steam boilers, (pressurized) hot-water installations as well as condensate and feedwater tanks. The conductivity controller indicates when the preset MAX or MIN conductivity is reached, opens or closes a continuous blowdown valve and may also control an intermittent blowdown valve.
The conductivity controller can be used together with conductivity electrodes and transmitters in the following equipment combinations: Conductivity controller LRR 1-52 together with conductivity electrodes LRG 12-2, LRG 16-4, LRG 16-9, LRG 17-1 and LRG 19-1; Conductivity controller LRR 1-53 together with conductivity transmitters LRGT 16-1, LRGT 16-2 and LRGT 17-1.
