Heat Detector HTD-8800/8811-FLP
The HTD-8800/8811-FLP Heat Detector is an innovative solution for detecting heat build-up in various industrial settings. Unlike conventional heat detectors, this device operates with a unique configuration. It features a Potential-Free NO (Normally Open) contact output, which remains open when the ambient temperature is below the set point and becomes short when the temperature exceeds the set point. The detector has a wide temperature range of 40°C to 90°C, with a factory preset option available. Designed for reliability, the detector offers fast response to overheat conditions and comes equipped with auto-reset functionality, resetting itself after the temperature cools down. With low power consumption (less than 3W), it ensures energy efficiency. The electrical specifications include a supply voltage range of 18 to 36 VDC and two relay contacts for primary and secondary alarms.
