4. 설정 및 설치
Proper installation is crucial for the accurate and reliable operation of the MBS 3000 pressure transmitter.
4.1. Mechanical Installation (Pressure Connection)
The MBS 3000 features a G 1/4" pressure connection.
- Ensure the pressure port and mating connection are clean and free from debris.
- Apply appropriate thread sealant if necessary, according to system requirements.
- Carefully screw the transmitter into the pressure port. Do not overtighten. Refer to the system's torque specifications.
- Ensure the transmitter is securely mounted to prevent vibration-induced damage.

Figure 3: Detail of the G 1/4" pressure connection.
4.2. Electrical Installation (DIN Plug)
The electrical connection is made via a standard DIN plug.
- Disconnect power to the circuit before making any electrical connections.
- Wire the DIN plug according to the wiring diagram provided with your specific model or system documentation. The standard output signal is 4-20 mA.
- Ensure correct polarity for power supply and signal lines.
- Securely attach the DIN plug to the transmitter's electrical connector.
- Verify all connections are tight and properly insulated to maintain the IP65 enclosure rating.

5. 사용 설명서
Once properly installed and powered, the MBS 3000 pressure transmitter will begin to measure pressure and output a corresponding signal.
- 전원 켜기: The transmitter has a power-up time of less than 50 ms.
- 신호 출력 : The standard output is 4-20 mA, linearly proportional to the measured pressure range (e.g., 4 mA for 0 bar, 20 mA for 16 bar). Other output signals (0-5 V, 1-5 V, 1-6 V, 0-10 V, 1-10 V) may be configured depending on the specific model.
- 모니터링: Connect the output signal to a compatible control system, PLC, or display unit to monitor the pressure readings.
- 응답 시간: The device has a fast response time of less than 4 ms, ensuring quick and accurate pressure updates.
6. 유지관리
The Danfoss MBS 3000 is designed for minimal maintenance. However, periodic checks can help ensure long-term reliability.
- 시각적 검사: Regularly inspect the transmitter for any signs of physical damage, corrosion, or loose connections.
- 연결 무결성: Ensure the electrical and pressure connections remain tight and free from leaks.
- 청소: If necessary, clean the exterior of the transmitter with a soft, damp 천. 연마성 세척제나 용매를 사용하지 마십시오.
- 재보정: While the MBS 3000 is factory calibrated, periodic recalibration may be required depending on application demands and regulatory requirements. Consult a qualified technician for recalibration services.
