SIEMENS LFS1.21A2 Flame protection device

The detector UV unit is located behind the rotary louver at the front of the detector tube, and the louver flange is connected to the shell. Quartz glass windows can protect pipes and louvers from dust. The wear-resistant housing can accommodate the stepper motor and electronic equipment driving the shutter to control the shutter.

The burner electric eye Siemens SIEMENS flame detectors LFS1.21A2 and LFS1.11A2 can replace LFE10 and LAE10. Take DF1191 single-band infrared flame detector as an example, DF1191 single-band infrared flame detector (Siemens), microprocessor-controlled signal evaluation.

Fuzzy algorithm and Zui new harmonic analysis function and targeted application algorithmIt has strong anti-false alarm ability. Siemens flame detector is suitable for detecting the fire caused by combustible liquid and gas as well as the smoky open fire caused by carbon-containing substances, such as wood, plastic, gas, petroleum products, etc. Installation of Siemens flame detector. Mount the Siemens infrared flame detector on a firm and shockproof plane. For indoor application, use the mounting bracket MV1, which can keep the detector accurate inclination; When the detector needs to be aligned with the monitoring site, use the ball hinge MWV1. For outdoor applications, use the rain cover DFZ1190. It has strong resistance to electromagnetic interference, sunlight and thermal radiation, humidity and corrosion. The DF1191 flame detector is only equipped with one sensor, with high performance ratio. Angle of view (Zui is less than 90 °). Built-in short-circuit isolator. It is applicable to detect the fire caused by flammable liquid and gas and the smoky open fire caused by carbon-containing substances, such as wood, plastic, gas, petroleum products, etc. DF1191 can only be used indoors. Install the infrared flame detector DF119X on a firm and shockproof plane. For indoor applications, use.
