The GESTRA LRS 1-5 (commonly documented as LRS 1-5b) is a conductivity limit switch used for monitoring the electrical conductivity of liquids. Together with a compatible GESTRA conductivity electrode, it detects when a preset conductivity limit is exceeded and operates a relay contact for alarm or control purposes.
Features
- Adjustable conductivity limit monitoring
- Two selectable conductivity measuring ranges
- 1% switching hysteresis
- Manual temperature compensation
- Volt-free relay output for alarm/control circuits
- LED indication of conductivity status
- Compatible with GESTRA conductivity electrodes
- Compact DIN-rail mounting
- Suitable for continuous industrial monitoring
- Useful for detecting contamination in condensate return systems
- Designed for boiler-water and water-quality monitoring applications.
Typical Applications
- Steam boiler TDS monitoring
- Marine boiler salinity/conductivity monitoring
- Boiler-water quality control
- Condensate contamination detection
- Feedwater monitoring
- Water-treatment plants
- District heating systems
- Industrial process-water monitoring
- Paper and woodworking industries
- Dye-bath conductivity monitoring
- Boiler plants operating with limited supervision
