I. Why Customize a Pressure Sensor?
The pressure sensor is the core component of a pressure transmitter - it converts pressure signals into electrical or digital outputs, serving as the "heart" of the entire device.
For different application environments (such as high temperature, high pressure, corrosive media, or micro-pressure measurement), standard sensors often cannot fully meet system requirements.
In these cases, customized pressure sensors offer superior performance, dimensional compatibility, environmental adaptability, and optimized output interfaces - providing higher reliability and stronger competitiveness for your pressure transmitter.
II. Key Parameters to Confirm Before Customization
To help our engineering team design the right solution for you, please prepare the following core parameters before customization. These details directly affect the structural design, chip packaging, compensation method, and testing standards of the sensor.
1. Pressure Range
The pressure range determines the design of the sensing chip and diaphragm structure.
Required measurement range
Pressure type: Gauge, Absolute, or Differential
Accuracy requirements
2. Outer Diameter & Structure
The size and structure affect how the sensor integrates with your transmitter.
Sensor outer diameter, thickness, and installation space
Specific mounting interface requirements
3. Operating Temperature
Temperature conditions influence chip material selection, sealing materials, and temperature compensation design.
Medium and ambient temperature range
Any rapid temperature variations or thermal shocks
4. Measured Medium
The nature of the medium determines diaphragm and packaging material selection.
Type of medium (gas, liquid, oil, steam, etc.)
Whether the medium is corrosive, prone to scaling, contains particles, or is volatile
Material compatibility requirements
5. Output Signal
The output type must be compatible with your transmitter's circuit system.
Desired output: mV signal, UART digital signal, I²C, or others
Need for amplification, temperature compensation, or digital calibration
6. Wiring Method
Proper wiring ensures signal stability and reliable assembly.
Wire lead or Kovar pin connection
Cable length, shielding, and waterproofing requirements
7. Performance Parameters
These parameters define the sensor's quality and consistency.
Linearity, hysteresis, and repeatability requirements
Limits on temperature coefficients (TCO, TCS)
8. Supply Voltage
Supply voltage affects output amplitude and internal circuit design.
System voltage range (e.g., 5V DC, 10V DC)
Multi-voltage compatibility if needed
9. Temperature Compensation
Temperature compensation improves measurement stability, especially for precision transmitters.
Required accuracy over the full temperature range
Need for factory calibration and full-range temperature compensation
10. Quantity
Quantity information helps optimize tooling, production time, and cost.
Sample quantity and mass production requirements
Future plans for volume manufacturing
