No. 216-R detectors are pressure-sensitive ventilators designed to protect against the foraging destruction or potential fires in areas with high dust release. It is a special type of detector that works with a flammable dust explosion protection system, also known as a dust explosion suppression system.

The basic principle behind this device is that it monitors the pre-determined air pressure value within the area, and when that value deviates from the predetermined set value by more than a predetermined amount, an alarm is triggered.

To better understand the working principle of the No. 216-R, let\'s consider what the device is capable of. It is designed to detect the presence of flammable suspended dust in the working environment, and is usually used in conjunction with other devices such as fire suppression systems or spark arrestors. The device has two elements; a dust sensor and a pre-determined pressure switch. When the dust concentration in the air exceeds a predetermined amount, the dust sensor will detect the increase in dust particles and will set off an alarm. This alarm will alert personnel of the presence of the dangerous material. Meanwhile, the pressure switch will detect when the pressure drops below a predetermined level, and if the pressure is decreased further, it will trigger the fire suppression or spark arrestor system, thus suppressing the buildup of combustible dust.

Moreover, the NO.216-R device is also used to detect the presence of air contaminants in areas where dust is a common problem, such as industry plants. The device is equipped with a wide range of sensors, which can screen dust particles, flammable gases, vapors, and other air contaminants. The sensors are adjusted to the user\'s specifications, allowing for a maximum reaction time before the alarm is tripped.

The No. 216-R is also used in explosive-proof applications and dust-explosion-proof applications. In dust-explosion-proof applications, the device is able to detect flammable dust particles, and when these are detected, the alarm is triggered. In explosive-proof applications, the device is designed to sense the presence of combustible gases, vapors, and combustible liquids, and will trigger the alarm in the presence of any combustible material. This device can also detect the presence of radioactive materials in the environment.

In sum, the No. 216-R detector is a versatile device that can be used for a wide range of applications. This device is designed to detect the presence of hazardous materials in the workplace, and when a dangerous material is detected, an alarm is triggered, alerting personnel to the presence of such materials and allowing for the protection of personnel.
