Frequently Asked Questions (FAQ)
Q
What is the operating voltage range of the remote transmitter?
The remote transmitter operates within a wide voltage range of 10 to 30 VDC, making it compatible with most industrial power supply systems and ensuring stable performance across varying power conditions.
Q
What communication protocol does the transmitter support?
The transmitter uses RS485 as its communication interface and supports the Modbus RTU protocol at a baud rate of 9600 bps. This ensures reliable integration with SCADA systems, PLCs, and other industrial automation equipment.
Q
What is the measurement accuracy for pressure and dew point?
The transmitter provides high-accuracy measurements: Temperature accuracy: ±1℃, Pressure accuracy: ±0.5% FS (±1.0% FS at 20℃), and Dew point accuracy: ±3℃. These specifications ensure reliable and precise monitoring in demanding environments.
Q
Is the transmitter suitable for harsh outdoor environments?
Yes. The transmitter carries an IP65 protection rating, making it dust-tight and protected against water jets. It also operates reliably across a wide ambient temperature range of -40℃ to +80℃ with relative humidity up to 95% RH, suitable for both indoor and outdoor industrial deployments.
Q
Can the pressure measuring range and process connection be customized?
Yes. The standard pressure measuring range is 0 ~ 1.4 MPa and the standard process connection is G1, both of which can be customized to meet specific application requirements. Please contact the manufacturer for custom configuration options.
Q
What EMC standards does the transmitter comply with?
The transmitter complies with multiple IEC 61000-4 EMC standards, including Level 4 for IEC61000-4-2, 4-4, and 4-5, Level 3 for IEC61000-4-3 and 4-6, and Level 5 for IEC61000-4-8, 4-9, and 4-10. This ensures excellent electromagnetic compatibility and reliable operation in electrically noisy industrial environments.
