ITEK HSS 2000 EX-1 Exproof Gas Alarm Device and Sensor Housing: Safety in Explosive Environments
The ITEK HSS 2000 EX-1 Exproof Gas Alarm Device is a high-security gas detection solution required for use in locations at risk of explosive atmospheres (ex-proof environments), such as industrial kitchens, boiler rooms, and central systems. The device detects explosive gases (natural gas/methane, LPG/butane/propane) in the environment, ensuring complete safety of life and property.
Gas Alarm Device Structure and Explosion-Proof Protection
ITEK HSS2000 EX-1 Gas Alarm Device consists of three basic components to meet the main functional and safety requirements:
Gas Alarm Panel: It is the main unit where control and alarm signals are processed, but this panel is not Ex-proof and cannot be placed in potentially explosive atmospheres.
Sensor Housing: This is the ex-proof section where the sensor that detects gas is located.
Cable: Ex-proof cable suitable for use in EX atmosphere must be used.
Gas Alarm Device Sensor Protection Details:
The sensor is placed in a sleeve and sealed with sinter .
Thanks to this housing, the sensor is not affected by liquid factors such as heat, water and oil.
Sensor Protection Degree: ATEX II 2G Ex d II BT6 / IP65 . This indicates that the device is explosion-proof and resistant to outdoor conditions (water and dust).
Gas Alarm Device Technical Specifications and Control Functions
Detected Gases: Natural Gas (Methane) and LPG (Butane, Propane).
Power Source: It operates with standard mains voltage of 220 VAC ± 10% (50-60 Hz) .
Gas Volume Ratio: Alarms at 10% LEL (Lower Explosive Limit) or 5,000 ppm .
Alarm Output: Red LED and 85 dB (minimum) audible buzzer are activated when hazardous gas is detected.
Relay Output: 250 VAC 5A (maximum) relay output can be connected to external devices such as solenoid valves in case of alarm. When connected to a solenoid valve, gas flow is cut off in case of danger.
Calibration Time: The device requires a calibration period of 60 seconds (45 seconds in some versions) when first energized or after a power outage.
Temperature Range: Can operate between -20°C and +50°C ambient temperatures.
Gas Alarm Device Usage Areas and Installation
Mandatory Areas of Use: Industrial kitchens, boiler rooms, central systems, LPG/gas stations and military.
Mounting: The sensor must be mounted on a fixed location within 1 meter of any area where explosive gases are used (such as a combi boiler, water heater, stove, or oven). If LPG is used, the sensor must be mounted close to the ground (at a maximum height of 10 cm).
