Hydraulic Pressure Sensor HK1100C

The HK1100C Pressure Sensor is a versatile and industrial-grade analog pressure transducer designed for precise measurement of fluid or gas pressure in hydraulic systems, pneumatic equipment, oil/water/gas applications and automation environments. Housed in a stainless-steel package with a standard socket/quick-connect pressure interface (e.g., G1/4), it offers reliable performance and convenient installation.

Key Features & Benefits

• Designed for easy replacement and installation, with robust stainless-steel body and ¼″ or G1/4″ pressure port. isweek.com+1

• Supply voltage nominally 5 VDC; analog output linearly spans 0.5 V (zero pressure) to 4.5 V (full scale). mallimages.ofweek.com+1

• Typical pressure range: 0 to 1.2 MPa (≈0–12 bar) with proof/burst ratings ~2.4–3.0 MPa. isweek.com+1

• Fast response time (≤2 ms) and working current ≤10 mA ensure compatibility with microcontroller based data acquisition. en.ofweek.com

• Suitable for measurement of non-corrosive media: hydraulic oil, water, gas, etc. Operating temperature typically 0–85 °C (storage up to 100 °C). mallimages.ofweek.com+1

• Accuracy around ±1.5 %FSO, with full temperature range error about ±3.5 %FSO. isweek.com

Working Principle & Integration

The HK1100C utilises a thin-film or silicon piezoresistive sensing element that responds to applied pressure. As the pressure increases, the sensing element deforms, altering its resistance. This change is converted into a proportional analog voltage output (0.5-4.5 V) relative to the supply voltage. You can connect the sensor’s signal output to an analog input on microcontrollers such as Arduino or Raspberry Pi (via an ADC) or to a data-logger for continuous monitoring.

For integration, ensure the sensor is supplied with stable 5 V, properly grounded, and the media to be measured is compatible (non-corrosive for standard version). The output voltage must be mapped via calibration to actual pressure values — many users implement a simple formula:
