When introducing domestic pressure measurement film specifications, we usually highlight four commonly used models: LW, LLW, LLLW, and LLLLW, also referred to as 1L, 2L, 3L, and 4L. Below is a detailed overview of their respective pressure measurement ranges.
- Model: LW (Low Pressure)
Type: Double-layer
Pressure Measurement Range: 2.5 MPa – 10 MPa
Product Size: 270mm × 10m
- Model: LLW (Ultra-Low Pressure)
Type: Double-layer
Pressure Measurement Range: 0.5 MPa – 2.5 MPa
Product Size: 270mm × 6m
- Model: LLLW (Extra-Ultra-Low Pressure / 3LW)
Type: Double-layer
Pressure Measurement Range: 0.2 MPa – 0.6 MPa
Product Size: 270mm × 5m
- Model: LLLLW (Micro Pressure / 4LW)
Type: Double-layer
Pressure Measurement Range: 0.05 MPa – 0.2 MPa
Product Size: 320mm × 3m
These four models represent the commonly used pressure measurement film specifications, along with their corresponding pressure ranges.
In practical applications, besides selecting the appropriate pressure range, it is also important to consider actual process conditions. As modern products demand higher stability, understanding the operating temperature during processing is crucial for accurate pressure measurement results.
