Unit Tube Pressure

SKU:U130

Description

Tube pressure is a wide range air pressure sensor that supports -100 ~ 200Kpa. You can connect one end of the tube to the gas inlet. This sensor transmitted onto mapping value -100 ~ 200Kpa and 0.1 ~ 3.1V voltage output. Also having a protective housing for long term stability. It’s an accessory that your industrial use cannot live without.

Features

• Includes Integrated piezo-resistive pressure sensor with wide temperature compensation
• Linear output, easy to use
• Measurement range: -100 ~ 200Kpa
• Output: 0.1 ~ 3.1V
• Precision: 1.5Kpa
• 2x LEGO compatible holes

Include

• 1x Tube Pressure Unit
• 1x HY2.0-4P cable

Applications

• Air pressure measurement

Specifications

Output voltage and pressure value conversion

• P: 実際の測定圧力値、単位（Kpa）
• Vout: センサー電圧出力値
• K, B: センサーモデル MCP-H10-B200KPPN に対応する係数値とオフセット値（K = 100、B = -110）
• 計算式: P = K × Vout + B

float K = 100.0;
float B = 110.0;
float P = analogVolts * K - B;

    float K = 100.0;
    float B = 110.0;
    float P = analogVolts / 1000.0 * K - B;
    Serial.printf("Pressure: %f.2 Kpa \n", P);
    delay(100);  // delay in between reads for clear read from serial
