Intrinsically Safe Fixed Gas Detector SENKO SI-100 Series

Intrinsically Safe Fixed Gas Detector SENKO SI-100 is certified ATEX Zone 1 used in hazardous areas where the potentially flammable gas atmosphere may be present. Backed up with IECEx and KCS approval. The SENKO SI-100 is a fixed gas detector installed in the place where a potential gas hazard exists to measure oxygen, toxic gas, and combustible gas.

The SENKO SI-100 shows not only the concentration of gas but also the diagnostic result of the unit itself through the LCD display and can connect to the controller with a standard 4-20 mA analog output communication or RS-485 digital communication.

SENKO SI-100 fixed gas detector consists of top case assy, bottom case, and sensor part assy enclosure. Threaded and cemented joints were applied for the enclosure. The material of the enclosure is ADC12 AL.

Among the excellent features included such as electrical data of 9 V to 34 VDC (Max 130 mA at 12 V), ambient temperature range of -20 °C < Ta < +55 °C, Max 1.6 W power consumption, wall mount type, aluminum, stainless steel(STS304) material and IP65
