Frequently Asked Questions

Q: Which sensing technologies are used in this detector?

The D1 utilizes four main technologies: Electrochemical for toxic gases, Infrared for specific hydrocarbons, Photoionization (PID) for VOCs, and Semiconductor sensors for a wide range of combustible gases.

Q: Is this device suitable for hazardous explosive environments?

Yes, it is specifically designed for hazardous areas with a Flameproof type certification (Ex d IIC T6 Gb) and an IP66 protection grade against dust and water.

Q: How does the remote calibration function work?

The device features an infrared remote control interface, allowing technicians to adjust parameters and perform calibrations without opening the explosion-proof enclosure, significantly increasing safety and efficiency.

Q: Can the D1 be integrated into an existing SCADA system?

Absolutely. With its dual output support (4-20mA current loop and RS485 Modbus RTU), it is fully compatible with most industrial PLCs and SCADA monitoring platforms.

Q: What happens if the sensor fails or short-circuits?

The detector has built-in intelligence to automatically identify and display faults such as over-concentration, sensor short circuits, or open circuits, facilitating immediate troubleshooting.

Q: How often should the sensors be replaced?

Replacement intervals depend on the gas type and concentration. Thanks to the plug-in sensor process, replacing the sensing component is a simple, tool-free operation that minimizes downtime.
