A3: Typically, Bently Nevada velocity sensors such as Velomitor or similar 1/2‑20 UNF thread velocity transducers are mounted inside this housing.

Q4: What does the “02” suffix in the model number signify?
A4: The “02” at the end of the part number indicates the cable exit fitting option is an explosion‑proof fitting, suitable for hazardous installations.

Q5: What environmental conditions is this housing designed for?
A5: It is built to protect sensors from harsh industrial conditions, corrosion, moisture, and explosive atmospheres typical in process plants, with a wide operating temperature range.

Q6: Does this housing include the velocity sensor?
A6: Depending on the specific suffix codes in the part number, this housing may be shipped with or without a velocity transducer; the version listed with no transducer options requires a separate sensor.

Q7: What mounting thread is used for installing the velocity sensor inside the housing?
A7: It typically uses a 1/2‑20 UNF internal thread to secure the velocity transducer.

Q8: Is this product suitable for non‑hazardous environments?
