Integration & Installation
4–20 mA (2-leder): Best for long noisy runs to PLC/BMS. Use 12–36 VDC loop power and keep loop impedance within spec.
0–10 V: Simple to panel meters/DAQ; ensure high-impedance input (>10 kΩ) and clean supply.
Mekanisk: Mount away from check/solenoid valves to reduce hammer; add a snubber; orient process port upward when possible to avoid air pockets.
- Confirm overload/burst vs. transient spikes.
- Select seal materials for temperature and chemistry.
- For ΔP tubing, use equal length and add drip loops/air traps.

Differenstryksensor vs transducer vs transmitter
| Enhed | Produktion | Typisk brug | Fordele | Overvejelser |
|---|---|---|---|---|
| ΔP-sensor (kort/kompakt) | Ratiometrisk / I²C / SPI | Indlejrede enheder, instrumenter | Lille, lavt strømforbrug, omkostningseffektiv | Kræver værtselektronik og kabinet |
| ΔP Transducer | 0–10 V / 4–20 mA | PLC/DAQ måling | Enkel ledningsføring, lange kabelføringer | Eksternt display/relæer medfølger ikke |
| ΔP sender | Konditioneret + kabinet (ofte display/relæer) | Feltinstallation, panelmontering | Robust, installatørvenlig | Største størrelse og højeste pris |

Ofte stillede spørgsmål (FAQ)
What range should I choose for water systems?
0–6 bar for RO/UF, 0–10 bar for building water and HVAC loops, 0–16 bar for boosters/sprinklers, and up to 25 bar for boilers. Use compound ranges if slight vacuum occurs.
Which diaphragm and seals are best?
SS316L suits most water; ceramic improves tolerance to pulsation/solids. Choose EPDM for potable water, FKM for hot water, and PTFE for chemical compatibility.
How to mitigate water hammer?
Install a snubber/restrictor, place the sensor away from fast valves, and consider accumulators; verify overload and burst ratings.
Can I monitor filter fouling?
Yes. Use a differential pressure transducer across the filter housing to trend ΔP and plan cartridge changeouts.
Do you offer sanitary or flush-diaphragm builds?
Yes. We can customize tri-clamp and flush-mount process connections for food/pharma water with CIP/SIP.
What documentation can I get?
Standard test reports are included; calibration certificates and serialized labels are available per your QA program.
