Arcteq AQ-02 - Arc Flash Point & Pressure Point Sensor.

Arcteq AQ-02 is an arc light point sensor with a light-sensitive photodiode element activated by arc light and a pressure point sensor.

The AQ-02 sensors should be mounted in the switchgear cubicles in such a way that the light-sensitive part covers the protected area as completely as possible.

Only one sensor should be used per one closed metal-clad compartment.
In open spaces (such as a busbar section) the sensors should be mounted no more than two meters apart.

The default light intensity threshold for an AQ-02 sensor is 8,000 lux.
Depending on the demand of the application, the default threshold can also be set to 25,000 lux or 50,000 lux.

An arc light sensor does not require further settings by the user. Its detection radius is 180 degrees.

Features:

• Light intensity threshold: 8,000 lux (25,000 & 50,000 lux can be delivered as an alternative).
• Pressure threshold: 0.2 bar above ambient pressure.
• Pressure measuring accuracy: ±1.8 % (of full scale)
• Pick-up time: <1 ms.
• Detection radius: 180 degrees.
• Mechanical protection: IP 20.
• Wiring arrangement: standard shielded twisted pair 0.75 mm² (AWG:18).
• Maximum sensor cable length (per channel): 200 meters.
• Operating temperature: –20...+85 °C.
• A maximum of three sensors connected in series.
