Troubled by selecting the PT500-50M-10V-0.5-M20-3m-503 pressure transmitter? As a professional manufacturer of diffused silicon liquid and gas pressure sensors, Xi'an Shenghongchuang analyzes the 5 core parameters of range, accuracy, output signal, port size, and cable length for you, helping industrial users precisely match application requirements.

I. Range Selection: The Key to Matching the Pressure Range of the Medium

The range parameter of the PT500 series pressure transmitter (for example, 50M indicates 50MPa) directly determines its applicable scenarios. Industrial users need to conduct a comprehensive evaluation based on the following dimensions:

1.1 Analysis of Medium Pressure Characteristics

For the pressure fluctuation characteristics of liquid/gas media, it is recommended to reserve a 20% safety margin. For example, in petrochemical industry applications, the DG1300-BZ-A-2-210/CJ/GZ pressure transmitter is usually selected with a range specification 1.5 times higher than the maximum working pressure.

1.2 Industry Standard Comparison

II. Accuracy Class: How 0.5%FS Affects Measurement Reliability

The nominal 0.5% accuracy indicator (such as 0.5 in PT500-50M-10V-0.5) is a core parameter for evaluating transmitter performance:

• Temperature Effect: The temperature drift of the diffused silicon sensor within the range of -20~80℃ must be ≤0.1%/10℃
• Long-term Stability: High-quality models such as EDYLBSQ-43 should have an annual drift of <0.2%FS
• Calibration Cycle: It is recommended to formulate a maintenance plan with reference to the ASTM E74 standard

III. Output Signal Type: Adaptation Solution for 10V Voltage Output

The 10V output signal in PT500-50M-10V-0.5-M20-3m-503 needs to match the control system:

3.1 Signal Type Comparison

3.2 Signal Conversion Solution

When connection to a PLC system is required on site, a signal isolator paired with the MYR-22 pressure transmitter can be used to achieve 10V to 4-20mA conversion.

IV. Mechanical Interface: Installation Specifications for M20×1.5 Thread

The selection of the M20 threaded interface requires attention to:

• Sealing Method: Metal sealing is suitable for high-temperature hydraulic pressure, and O-rings are suitable for corrosive media
• Installation Torque: A preload of 40-60N·m is recommended
• Adapter Connector: The ZY800-V1-B1-C1-J1P1 series provides G1/2" to M20 adapter connectors

V. Cable Configuration: Engineering Practice for 3-meter Cable Length

Cable length selection needs to consider:

• Electromagnetic Interference Protection: It is recommended to use double-shielded cables (such as the standard JX-004 cable)
• Extension SolutionExtension Solution: The YM-YM300 series supports customized cables up to 20 meters
• Protection Rating: Models with IP67 and above can be directly buried for installation
