Unit Tube Pressure

SKU:U130

Description

Unit Tube Pressure is a positive and negative pressure gauge that supports a wide measurement range of -100 ~ 200Kpa. When in use, it is connected via a tube, with the other end connected to the gas measurement environment. The sensor maps the range -100 ~ 200Kpa to output a voltage of 0.1 ~ 3.1V. It comes with a fully enclosed protective shell, effectively ensuring the stability of the sensor, making it very suitable for applications such as gas pressure detection in industrial equipment.

Features

• Internally integrated and compensated pressure sensor

Voltage Output to Pressure Value Conversion

• P: Actual measured pressure value, unit (Kpa)
• Vout: Sensor voltage output value
  = K, B: Coefficient value and offset value corresponding to sensor model MCP-H10-B200KPPN (K = 100, B = -110)
• Calculation formula: P = K × Vout + B

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