Q1: What type of pressure does the 621‑6350 measure?

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

Q2: What is the pressure range of this model?

A2: The 621‑6350 measures pressures from 0 to 6350 PSI, suitable for very high‑pressure systems.

Q3: What output signal options are available?

A3: It offers selectable analog output: 4–20 mA current or 0–10 VDC voltage, depending on system requirements.

Q4: What is the accuracy of this sensor?

A4: Accuracy is ±0.5% of full scale, ensuring repeatable and stable pressure measurement.

Q5: What operating temperature range does it support?

A5: It operates reliably from –40°C to +125°C, suitable for extreme cold and heat.

Q6: What media can it measure?

A6: Compatible media include air, inert gases, and non‑corrosive hydraulic fluids.

Q7: What mechanical connection does it use?

A7: The sensor uses a 1/4″ NPT male threaded mechanical connection.

Q8: What environmental protection rating does it have?

A8: It has an IP67 rating, offering dust resistance and protection against temporary water immersion.

Q9: Is the sensor factory calibrated?

A9: Yes, the 621‑6350 is factory‑calibrated. Periodic verification may be recommended in critical applications.

Q10: In which industries is this sensor commonly used?

A10: It is widely used in industrial automation, hydraulic systems, mobile machinery, power generation, water/wastewater systems, and chemical/petrochemical processes.
