Wiring Diagram
Q1: Can a digital pressure transmitter measure high-pressure applications?
A1: Yes. The digital pressure transmitter supports optional measuring ranges from 0 to 60 MPa, making it suitable for many high-pressure industrial applications. With an overload pressure rating of 2 times the rated pressure, it provides reliable pressure monitoring for compatible gas and liquid media.
Q2: How does a digital pressure transmitter work?
A2: A digital pressure transmitter detects pressure through a sensing element, such as a diffused silicon sensor, and converts the resulting signal into a usable electrical output. The output can be transmitted to compatible monitoring equipment or control systems for pressure display, data recording, and process control.
Q3: What output signals does the digital pressure transmitter support?
A3: The digital pressure transmitter supports 4–20 mA analog output and RS485 digital output. The 4–20 mA interface is widely used in industrial control systems, while RS485 supports digital communication with compatible equipment. Verify the specific communication protocol and interface requirements before integration.
Tips: What causes unstable readings from a digital pressure transmitter?
Unstable readings can result from actual pressure fluctuations, electrical interference, an unsuitable power supply, loose wiring, vibration, temperature changes, or incorrect configuration. Check the process conditions and electrical connections first, then compare the transmitter output with a calibrated reference instrument to help identify the source of the problem.
