Wiring Diagram

Represents shielded cable. All marked grounding points must be effectively grounded. It is recommended to use shielded dual-core signal cables. To avoid ground loops, the shielding layer should adopt single-ended grounding. At the pressure transmitter end, the shielding layer should be left floating, and grounded at the control cabinet end.

Application

Application for research and development, measurement, control and control technology, vehicle technology, energy and environmental technology, mechanical engineering.

Tips: Are there any special considerations for using the amplifier?

For optimal performance, it is recommended to use shielded cables to minimize electromagnetic interference. Grounding the shielding layer at one end (single-ended grounding) can further reduce potential ground loops, which may affect signal quality. Additionally, proper installation within the specified environmental conditions ensures long-term reliability and accuracy.
