High-precision Displacement Measurement Inductive Pressure Transmitter For Harsh Environments

This is a displacement-to-electrical signal conversion technology based on the principle of electromagnetic induction, often used to convert the minute mechanical displacement caused by pressure into measurable electrical signals.

Main Features and Advantages

Robust structure and resistance to harsh environments: The sensing part (coil, core) has no semiconductor junctions, making it resistant to high temperatures, radiation, and strong electromagnetic interference (it is an electromagnetic component and requires shielding from external interference).
High resolution and sensitivity: Especially the differential transformer type, it can detect extremely small displacements (sub-micron level).
Long service life and high reliability: No contact wear (differential type), theoretically infinite service life.
Strong output signal: Usually has a large output signal amplitude and a good signal-to-noise ratio.
High response frequency: Suitable for measuring dynamic pressure changes.

Typical application scenarios

Aerospace :
- Engine oil pressure, hydraulic system pressure.
- Static and dynamic pressure measurement of aircraft (high reliability, wide temperature range requirements).
Industrial process control:
- Differential pressure measurement: combined with diaphragm or bellows, pressure is first converted into displacement, and then measured by LVDT. Commonly used in flow and liquid level calculation.
- Valve position feedback (utilizing its displacement measurement nature).
Laboratory and test bench:
- High-precision pressure calibration equipment, wind tunnel testing.
Energy and power:
- Oil pressure of turbine speed control system, pressure monitoring in specific nuclear power plant sections (radiation resistance).
Heavy machinery:
- Hydraulic system pressure monitoring of construction machinery and ships.

The inductive pressure transmitter is a classic technical approach that combines "high-reliability and high-precision displacement measurement" with "pressure measurement". It achieves stable measurement not through semiconductor characteristics but through precise mechanical structures and classical electromagnetic laws.
