Integration & Wiring
4–20 mA (2-wire): Best for long runs and noisy factories; 12–36 VDC loop power; check loop impedance.
0–10 V: Simple to panel meters/DAQ; ensure high-impedance input (>10 kΩ) and clean supply.
0.5–4.5 V / I²C (board-level): Stable 5 V supply, short leads, and good grounding practices.
- Add a snubber/restrictor for pulsating compressors.
- Use hydrophobic vents or drip loops to manage condensate.
- Shielded cables, grounded at one end, improve EMC.

Differential Pressure Sensor vs Transducer vs Transmitter
| Device | Izhod | Typical Use | Pros | Considerations |
|---|---|---|---|---|
| ΔP Sensor (board/compact) | Ratiometric / I²C / SPI | Embedded devices, instruments | Small, low-power, cost-effective | Requires host electronics and enclosure |
| ΔP Transducer | 0–10 V / 4–20 mA | PLC/DAQ measurement | Simple wiring, long cable runs | External display/relays not included |
| ΔP Transmitter | Conditioned + enclosure (often display/relays) | Field installation, panel mount | Rugged, installer-friendly | Largest size and highest cost |

Frequently Asked Questions (FAQ)
What ranges do you recommend for compressed air and pneumatics?
Typical FS ranges: 0–10 or 0–16 bar for pressure lines; −100…0 kPa for vacuum. For duct static, use low-range differential sensors in Pascals.
Which output should I pick for a PLC?
4–20 mA for long/noisy plant runs; 0–10 V for short panel/DAQ wiring; 0.5–4.5 V or I²C for embedded devices.
Can the sensor handle moisture and oil in compressed air?
Yes—select SS316L or ceramic diaphragms; add snubbers/filters and follow moisture management practices.
Can one device measure both slight vacuum and pressure?
Yes—choose a compound gauge range (e.g., −100…+100 kPa) if your cycle crosses zero.
What threads and connectors are available?
G1/4, 1/4-NPT, M14×1.5, etc.; connectors include M12, DIN, Deutsch/Packard, or cable pigtail.
Do you provide calibration documentation?
We include test reports and can supply calibration certificates with serialized labels upon request.
