The Ratiometric pressure sensor uses a voltage signal to represent the pressure.

✔ 0.5–4.5V Ratiometric Output: Stable analog signal for accurate pressure measurement
✔ Wide Pressure Range: Options up to 200 Bar
✔ Ideal for Embedded Systems: Compatible with Arduino, PIC, STM32, ESP32, Raspberry Pi & PLCs
✔ Direct ADC Connection: No external signal conditioning required
✔ Low-Voltage Operation: Runs from 3.3–5Vdc
✔ Multiple Mounting Options: M12 or IP65 cable outlet with G1/4 or NPT 1/8 ports
✔ Industrial-Grade Design: Suitable for automation, hydraulics and process control
✔ Secure Payments: Safe checkout with trusted providers
✔ Quick Delivery: Fast dispatch to keep projects on track

This voltage signal is proportional to the supply voltage, therefore the output is a percentage of the supply voltage. 

This type of pressure sensor is ideal for Raspberry Pi , Arduino and Embedded systems.

Therefore integration is simplified by avoiding complex analogue circuitry.

Ratiometric Pressure sensor Output Example

for example a Ratiometric pressure sensor with a range of 0-10Bar and the supply

Ratiometric output if supply voltage is 5V

0Bar = 0.5V = 10%

10Bar=4.5V =90%

Ratiometric output if Supply voltage is 3V

0 Bar = 0.3V = 10%

10Bar = 2.7V=90%
