Crystals

A crystal heat detector is one of the most reliable and proven methods for the detection of fire and other excessive temperatures. The 402F320XXCJT, from General Monitors, is a versatile and reliable industrial grade thermal alarm system capable of providing life-saving and fire prevention alerts. It utilizes advanced technologies, such as crystals, to detect rapid increases in temperature. This article will explore the application field and working principle of this device.

Application Field

The 402F320XXCJT is used in a variety of industrial and commercial settings, such as oil and gas refineries, chemical plants, and warehouses, where excessive temperatures can create hazardous conditions. It is also used in residential settings where smoke and fire alarms are installed. The device is suitable for installation in hazardous locations, as it is certified for the presence of potentially flammable or explosive atmospheres outlined in UL-67 and NFPA-72.

Working Principle

The 402F320XXCJT utilizes advanced technologies, such as crystals, to detect excessive temperatures. This type of sensor works by detecting the temperature of a material as its crystals expand and contract due to thermal energy. The crystals are made from special semiconductor materials which have a high sensitivity to temperature changes. When the temperature exceeds a certain set limit, the crystal reacts and produces a voltage change, which then triggers an alarm.

One of the major benefits of the 402F320XXCJT, besides its design and small size, is its accuracy. The device has a tolerance level of 0.5°C and an operational range of -20°C to +150°C, making it suitable for a variety of applications. In addition, the device can be recalibrated for accurate temperature measurements over long periods of time.

The 402F320XXCJT is a reliable, easy-to-install, and cost-effective solution for detecting excessive temperatures. It utilizes crystals to detect and alert to increases in temperature, making it an effective solution for providing fire prevention alerts. Its low power consumption, small size, and advanced features make it an attractive option for applications where reliability and accuracy are paramount.
