8. Frequently Asked Questions (FAQ)

Q1: What type of pressure does the 621‑6575R measure?

A1: It measures gauge pressure, which is the pressure relative to atmospheric pressure.

Q2: What is the pressure range of this model?

A2: It measures pressures from 0 to 6575 PSI, suitable for extremely high‑pressure industrial systems.

Q3: What output signal options are available?

A3: The sensor offers selectable 4–20 mA current output or 0–10 VDC voltage output, allowing integration with PLCs and controllers.

Q4: What is its accuracy?

A4: The typical accuracy is ±0.5 % of full scale, which provides stable and reliable pressure readings.

Q5: What operating temperatures can it withstand?

A5: It operates reliably in temperatures from –40 °C to +125 °C, covering extreme environmental conditions.

Q6: What media is it compatible with?

A6: It is compatible with air, inert gases, and non‑corrosive hydraulic fluids. Confirm media compatibility for specific applications.

Q7: What type of mechanical connection does it use?

A7: The sensor uses a standard 1/4″ NPT male threaded mechanical connection widely used in industrial systems.

Q8: What environmental protection does it have?

A8: With an IP67 rating, it is protected from dust ingress and temporary water immersion.

Q9: Is the sensor factory calibrated?

A9: Yes, the 621‑6575R is factory calibrated and ready for installation. Periodic calibration verification is recommended in critical systems.

Q10: In which industries is this model commonly used?

A10: It is widely used in industrial automation, heavy machinery, hydraulic systems, energy production, water/wastewater management, and chemical processing where accurate high‑pressure measurement is essential.
