产品概述

FIREYE InSight 系列的95IR、 95UV和 95DS型火焰检测器是基于微处理器设计的火焰探头,使用固态的红外线传感器(IR)、紫外传感器(UV)或双传感器(IR和UV)。此系列火检探头均带有内部火焰继电器,ON/OFF门槛值可调,因此不需远程放大器。[nSight系列检测器可完美替换FIREYE 45FS1和 45UVFS1系列探头,以及45RM4系列探头,可以检测单燃烧器或多燃烧器工况下目标火焰的有或无。Insight探头检测目标火焰产生的调制振幅(即火焰的闪烁特性)。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头增益。InSight 95IR、 95UV和 95DS 探头,每种都因功能的不同而被分为两种型号。
标准型S1,有三种火焰闪烁频率可选择,传感器增益可调,火焰继电器ON/OFF门槛值可调,4-20mA模拟信号强度输出,故障继电器输出,2个可选编程文件来存储设定值(用于两种不同的燃料或燃料比率)。
扩展型S2.增加了带有手动旁通的自动编程(自动设定)功能,21个火焰闪烁频率可选,共4个可选择的编程文件来存储设定值,还增加了通过用Fireye基于Windows95/98/NT的用户应用软件的远程通讯功能。
所有 FIREYE InSight 探头均需要24 Vdc电源,有电子自检功能(不需机械快门),设有可显示8位字母数字LED屏和4个按钮式小键盘使用户可以查看运行参数和选择设定值。“CG” 型号的探头包括一根10英尺(3米)长的自带电缆和电缆密封件。非“CG”型号的探头的电缆则是12针快拆接头连接。也有可以连接光纤的型号。请参看CU-101手册中的安装说明。

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。

Type 95IR 红外火焰传感器,对红外线波长的响应范围是700到1700 nm。适用于燃料是煤和油的工况。
Type 95UV 紫外火焰传感器,对紫外线的波长响应范围是295到320 nm。适用于燃料是气体的工况。
Type 95DS 同时设有上述的红外和紫外传感器。适用于多种燃料混烧的工况。标准型 S1 适用于不需要很高要求或者不需要扩展型S2所具有的远程通讯功能的多种工况。(例如单燃烧器锅炉和工业炉,烟道补烧器等)
扩展型 S2 适用于需要最高检测要求和最大灵活性(增加调制频率的选择,省时自动设定功能)和远程通讯能力的工况(例如大型多燃烧器锅炉和工业炉)。

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).
