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

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:

Applications

• Hydraulic systems pressure monitoring

• Oil, water or gas pressure measurement in industrial settings

• Pneumatic control systems

• Automation and IoT applications requiring pressure feedback

• Microcontroller-based sensing and data-acquisition projects

• HVAC, refrigeration and compressor pressure monitoring

Precautions

• Do not exceed the specified burst or proof pressure ratings — this may permanently damage the sensor.

• Avoid exposure to corrosive fluids unless sensor variant designed for that medium is used.

• Ensure correct wiring and stable 5 V supply; voltage spikes may affect accuracy.

• For microcontroller usage, ensure the analog input can read up to ~5 V or scale accordingly.

• Avoid vibrations or mounting conditions that stress the pressure port.

• Calibration is recommended if high accuracy is needed.

Why Choose HK1100C?

With its rugged stainless-steel construction, fast response, high accuracy and analog output format, the HK1100C offers a cost-effective solution for engineers, hobbyists and automation designers alike. Whether you’re building a pressure monitoring system, integrating into IoT, or working with Arduino-based prototypes, this sensor offers both simplicity and precision.
