Limit Controllers

Industrial limit controllers operate as independent safety sentinels designed to protect personnel, machinery, and valuable products from catastrophic thermal runaway. Functioning alongside primary temperature regulators, these high-limit and low-limit safety switches constantly monitor process inputs via dedicated sensors. If a critical temperature threshold is breached, the controller instantly latches a lockout relay to cut power to heating or cooling elements, remaining securely tripped until a manual operator reset is performed in accordance with factory safety compliance protocols.

Branom Instrument Co. supplies a robust selection of FM-approved limit controllers engineered for high-risk industrial environments. Our inventory features compact panel-mount units and rugged DIN-rail modules that integrate seamlessly into existing control panels to provide reliable, failsafe emergency shutdown functionality. Our technical team is ready to assist you in selecting models with the appropriate safety ratings, latching configurations, and alarm outputs to ensure your thermal systems fully meet rigorous factory safety standards.
