OC-F08 Fixed LPG Gas Detector 0-100% LEL Catalytic Combustion, Exd IIC T6 Gb IP66

Description：

The OC-F08 is a fixed, wall-mounted LPG gas detector built around a catalytic combustion sensor and calibrated for 0-100% LEL. It is designed for continuous monitoring of liquefied petroleum gas at storage areas, filling plants and burner fronts, where a leak has to be caught long before the atmosphere reaches the lower explosive limit.

• Catalytic combustion sensing for LPG

The sensor reads LPG across the full 0-100% LEL range with 1% LEL resolution and a T90 response time of 30 seconds or faster. Precision is ±3% F.S., repeatability ±2%, and zero drift is held to ±1% F.S. per year. Readings can be displayed in ppm, %LEL, %vol or mg/m3, and the LCD shows the gas concentration, gas type, unit and instrument status at the same time. The sensor carries a 2-3 year service life.

• Built for Zone 1 and Zone 2 areas

The enclosure is die-cast aluminium with a hard alumina air chamber, rated Exd IIC T6 Gb for combustible gas service and sealed to IP66. The detector runs from -40 to 70 °C at 10-95% RH(non-condensing) and 86-106 kPa; above 90% RH a filter can be added. Power is 24 V DC nominal, accepted across 10-30 V DC, drawing under 2.5 W. Electrical entries are 3/4" NPT and 1/2" NPT female; mounting is wall or pipe type on an M40×1.5 thread. The complete unit measures 185 × 137.2 × 90.7 mm and weighs about 1.6 kg.

• Outputs for PLC, DCS and alarm panels

Standard output is a three-wire 4-20 mA analogue signal, suitable for direct connection to a PLC, DCS or controller. Optional outputs are a four-wire RS485 digital signal, a 200-1000 Hz frequency signal, and a two-level relay output (220 VAC 0.5 A / 5 VDC 0.5 A, plus two sets of passive relays rated 24 VDC 2 A). Signal transmission reaches 2000 m without a repeater; beyond that a repeater can be added. Audible-visual alarm and relay alarm are both supported.

• Maintenance without opening the housing in a hazardous area

The detector uses an intelligent sensor in a modular design with an independent air chamber: the sensor is identified automatically with its key parameters, and replacing it does not require recalibrating the detector. Settings are changed with an infrared remote control, so the cover stays closed in a hazardous area. Acquisition runs on a 16-bit ADC with a four-layer circuit boardfor high anti-interference in electrically noisy plants.

Features：

• 4-20mA standard analog signal and RS485 digital signal output, 200~ 1000HZsignal output, relay output (optional);

• Intelligent sensor, modular design, easy maintenance

• Display the gas concentration in ppm, %LEL, %vol and mg/m3 is selectable;

• LCD screen displaying the gas concentration, gas type, unit, instrument status etc.

• Independent  air  chamber,  the  sensor  is  not  required  to  replace  the  sensor  calibration, automatic identification of key parameters of the sensor;

• Infrared remote control operation, avoid cover opening operation in dangerous situations.

• With the  16bit ADC  acquisition  chip,  designed  with four-layer  circuit  board,  so with  high anti-interference ability;

• With the Ex-proof certificate, the Ex-proof grade is Exd II CT6.
