Frequently Asked Questions

What is the communication protocol and interface of this methane sensor?

The sensor uses an RS485 serial interface and communicates via the standard Modbus-RTU protocol. Both the Modbus device address and the baud rate are user-configurable, supporting long-distance network integration of up to 2000 meters.

What power supply is required for the RS-CH4-N01-2 sensor?

It operates on a wide-range 10-30V DC power supply, making it compatible with various industrial DC power sources. The device has a low power consumption of 0.9W, simplifying power system design.

In what environments can this sensor be safely installed?

It is designed for harsh and hazardous environments. The sensing element is explosion-proof (ExdIMb rated), and the unit is housed in a wall-mounted, waterproof enclosure. It operates reliably in temperatures from -40°C to +80°C and humidity up to 95% RH (non-condensing).

Can the measurement range of this sensor be customized?

Yes. While the standard range is 0-100% Lower Explosive Limit (LEL) for methane, the sensor can be factory-calibrated to other specific concentration ranges to meet unique application requirements.

Does the sensor include a local display?

The base unit does not include a display. However, an optional high-quality OLED display module is available, which allows for clear on-site viewing of methane concentration values, including in low-light conditions.
