Simplicity 65UV5 Flame Scanner

Mô tả :

The Fireye 65UV5 flame scanner is a microprocessor based flame scanner utilizing an ultraviolet tube-type sensor and an electro-mechanical self-checking shutter mechanism. The Fireye 65UV5 flame scanner incorporates an internal flame relay with a fixed ON/OFF threshold thereby eliminat- ing the need for an external flame amplifier.

The 65UV5 scanner is available with a one-second or four second flame failure response time (FFRT) depending on the model selected. The “E” versions are one second FFRT, the non-”E”ver- sions are four seconds FFRT. The Fireye 65UV5-1004QD, -1004EQD flame scanner provides an analog 4 to 20 mA output referenced to flame signal strength.

The Fireye 65UV5 flame scanner is powered from a 24 Vdc power source provided externally and includes an integral 8 pin quick disconnect connector. A color-coded internal LED indicates flame status and alarm condition. This can be viewed through a viewing port on the rear cover.

Ứng dụng :

65UV5 Fireye self-checking scanners are used to detect ultraviolet emissions from fossil fuel flames such as natural gas, coke oven gas, propane, methane, butane, kerosene, light petroleum distillates and diesel fuels.

Nguyên lý hoạt động :

65UV5 Fireye scanners use a UV-eye detector. This detector is a sealed, gas filled, UV-sensitive tube containing two electrodes connected to a source of DC voltage. When UV radiation of sufficient energy falls upon the electrodes, electrons are released and the inter-electrode gas becomes conduc- tive, resulting in an electric current flow from one electrode to the other. The current flow starts and ends abruptly and is known as an “avalanche.”

A very intense source of UV radiation will produce several hundred avalanches or pulses per second. With less radiation there will be fewer pulses per second. Upon total disappearance of flame, the detector output ceases. Thus, the presence or absence of pulses is an indication of the presence or absence of flame; the frequency of the pulses is a measure of flame intensity. When the pulses reach a sufficient level, the internal flame relay is energized.
