SC2L-95UVS2-1CEX 带有内部火焰继电器的 一体化火焰检测器

InSight探头检测目标火焰产生的调制振幅（及火焰的闪烁特性）。在探头的设定程序中，将会选择调制频率，这个数值会直接影响到最佳的火焰识别能力（ON/OFF值）。并可手动设定（S1型）或越过手动设定进行自动设定（S2型）来选择合适的调制频率和探头增益。选定了合适的闪烁频率后，输入火焰继电器的ON/OFF 门槛值。（此项选择在S2型号中可自动设置）。在4-20mA的信号强度输出中，小值（4mA）代表信号强度为“0”，最大值（20mA）代表信号强度为“100”。
火焰继电器 当信号强度达到或超过已设定的火焰“ON”的门槛值时被激励得电（常开触点闭合）。当信号强度达到并低于已设定的火焰“OFF”门槛值时，继电器失电（闭合触点打开）。当供电中断或检测到内部故障时，闭合触点也会打开。（参见下文）
故障继电器 当探头正常供电（24 Vdc）并且探头内部通过自检无误时被激励得电。当供电中断或内部检测到故障时失电。一个常开触点信号（来自故障继电器）被串联到火焰继电器的回路中，一个常闭触点信号用于报警显示。

95UVS2-1

The FIREYE InSight series 95IR, 95UV, and 95DS flame detectors are microprocessor-based flame probes that use solid-state infrared sensors (IR), ultraviolet sensors (UV), or dual sensors (IR and UV). This series of fire detectors are equipped with internal flame relays and adjustable ON/OFF thresholds, so no remote amplifier is required. [The nSight series of detectors is a perfect replacement for the FIREYE 45FS1 and 45UVFS1 series probes, as well as the 45RM4 series probes, which can detect the presence or absence of a target flame under single burner or multi-burner conditions. The Insight probe detects the modulation amplitude (i.e. the flicker characteristics of the flame) produced by the target flame. In the probe setting procedure, the modulation frequency is selected, which directly affects the optimal flame recognition (ON/OFF value). The appropriate modulation frequency and head gain can be selected manually (type S1) or automatically (type S2) beyond the manual setting. The InSight 95IR, 95UV and 95DS probes are each divided into two models for different functions.
Standard S1, with three flame flicker frequency options, adjustable sensor gain, adjustable flame relay ON/OFF threshold, 4-20mA analog signal strength output, fault relay output, 2 optional programming files to store setpoints (for two different fuels or fuel ratios).
The extended S2. Adds automatic programming (automatic setting) with manual bypass, 21 flame flicker frequencies to choose from, a total of 4 selectable programming files to store set values, and adds remote communication through Fireye’s Windows95/98/ Nt-based user application.
All FIREYE InSight probes require a 24 Vdc power supply, have an electronic self-test function (no mechanical shutter required), feature an 8-digit alphanumeric LED display and 4 push-button keypad allowing users to view operating parameters and select Settings. The “CG” model probe includes a 10-foot (3 m) cable and cable seal. The cable for non-CG models is a 12-pin quick-release connector connection. There are also models that can connect optical fibers. Refer to the installation instructions in the CU-101 manual.

The InSight probe detects the modulated amplitude generated by the target flame (and the flicker characteristics of the flame). In the probe setup program, the modulation frequency is selected, and this value directly affects the best flame recognition capability (ON/OFF value). The appropriate modulation frequency and probe gain can be selected by manually setting (type S1) or automatically setting (type S2) beyond the manual setting. After selecting the appropriate flicker frequency, enter the ON/OFF threshold value of the flame relay. (This option can be set automatically in the S2 model). In the signal strength output of 4-20mA, the small value (4mA) represents the signal strength of “0”, and the maximum value (20mA) represents the signal strength of “100”.
The flame relay is energized when the signal strength reaches or exceeds the threshold value of the flame “ON” that has been set (normally open contact closure). When the signal strength reaches and falls below the set flame “OFF” threshold value, the relay loses power (closed contact opens). The closing contact also opens when the power supply is interrupted or when an internal fault is detected. (See below)
The fault relay is energized when the probe is powered properly (24 Vdc) and the probe interior is correct through self-testing. Loss of power when the power supply is interrupted or an internal fault is detected. A normally open contact signal (from the fault relay) is connected in series to the circuit of the flame relay, and a normally closed contact signal is used for alarm display.

The Type 95IR infrared flame sensor responds to infrared wavelengths from 700 to 1700 nm. Applicable to the fuel is coal and oil conditions.
The Type 95UV UV flame sensor has a wavelength response range of 295 to 320 nm to ultraviolet light. Suitable for the fuel is gas condition.
The Type 95DS features both the infrared and ultraviolet sensors described above. It is suitable for mixed burning of various fuels. The standard S1 is suitable for a wide range of conditions that do not require the demanding or extended remote communication capabilities of the S2. (such as single-burner boilers and industrial furnaces, flue burners, etc.)
The extended S2 is suitable for applications that require the highest detection requirements and the greatest flexibility (increased modulation frequency choice, time-saving automatic setting function) and remote communication capabilities (such as large multi-burner boilers and industrial furnaces).
