Description
The Spirax-Sarco P6700111000010S152 High Limit HL100+ is an industrial safety and control component designed for monitoring and limiting process conditions in thermal and pressure-based systems. It is used as a high-limit controller that triggers a protective response when measured process values exceed preset safety thresholds, helping prevent equipment damage or operating conditions. This unit is applied where precise limit supervision is required for operational protection in HVAC systems. It continuously monitors input signals from connected sensors and activates control outputs when limits are exceeded. It supports equipment protection, process stability, and controlled shutdown or alarm operations.
