Overview & Working Principle
A pressure transducer converts fluid pressure into an electrical signal. Winsen integrates a stable sensing element (piezoresistive, capacitive, or piezoelectric), temperature compensation, and signal conditioning to deliver linear, low-noise outputs that are easy to read in PLCs, microcontrollers, or data acquisition systems.
Izberite merilnik for pressure relative to ambient, absolutno for pressure relative to vacuum, and diferencialno for the difference between two ports. For long cable runs and industrial noise environments, 4–20 mA is preferred; for low-power or MCU designs, ratiometric or digital outputs are ideal.

Integration & Wiring
Za 4–20 mA (2-wire) loops, power with 12–36 VDC and maintain loop impedance within transmitter compliance. For 0–10 V outputs, a 12–36 VDC supply and high-impedance input (>10 kΩ) are recommended. Ratiometric 0.5–4.5 V devices should use low-noise 5 V and short sensor leads. I²C/SPI variants share digital ground with the host and need proper pull-ups and cable shielding.
Example: 4–20 mA loop +24V ───── PLC 24V │ ├─────( + ) Pressure Transducer ( – )───── PLC AI (4–20 mA ) │ GND ───┴───────────────────────────────────────── PLC GND
Exact pinout varies by connector family (M12, DIN 43650, Packard, etc.). Refer to the product datasheet.

Pressure Transducer vs. Transmitter vs. Switch
| Naprava | Primary Output | Primer uporabe | Pros | Premisleki |
|---|---|---|---|---|
| Pressure Transducer | Analog (mA/V) or digital (I²C/SPI) | Closed-loop control, measurement, logging | Continuous signal, high resolution | Requires analog/digital input; proper wiring |
| Pressure Transmitter | Conditioned output, industrial housing | Field installation, long cable runs | Ruggedized, standardized connectors | Larger form factor; cost vs. bare transducer |
| Pressure Switch | On/Off (relay or transistor) | Alarms, interlocks, simple control | Simple, no analog input needed | No continuous measurement |
If you’re migrating from switches to transducers for better control, our team can help tune ranges and filters to stabilize your PID loops.
Pogosto zastavljena vprašanja (FAQ)
How do I choose gauge vs. absolute vs. differential?
Pick merilnik for line pressure relative to ambient (compressors, hydraulics). Use absolutno for vacuum or barometric-sensitive measurements. Choose diferencialno for measuring across filters, orifices, or rooms.
Can you match my connector and pinout exactly?
Yes. We support M12, DIN 43650, Packard, Deutsch, JST, and custom harnesses with pinouts to your standard, including color coding and labels.
What environmental protection levels are available?
Typical builds achieve IP65–IP67 depending on connector and cable sealing. We advise IP67 for wash-down and outdoor use.
Ali nudite potrdila o kalibraciji?
We offer factory test reports for each unit and can provide calibration certificates referenced to traceable standards as part of your PPAP or documentation pack.
Can you help me replace an obsolete model from another brand?
Yes. Share the part number, electrical output, thread, and range. We will propose a compatible form-fit-function replacement or adapter kit.
