FAQ
FAQ
Q1: What is the Bently Nevada CA21128‑00‑00‑02‑02 used for?
A1: It is an explosion‑proof velocity transducer housing assembly designed to house and protect a velocity sensor used for vibration monitoring on industrial rotating machinery in hazardous areas.
Q2: What does the CA21128 series indicate?
A2: The CA21128 series denotes an explosion‑proof version of the 21128 velocity transducer housing, certified for hazardous area use (Class I, II, III Division 1).
Q3: What type of sensors can be installed in this housing?
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?
A8: While it can be used in non‑hazardous environments, its primary design is for explosion‑proof applications; general housings without the “CA” prefix may be more cost‑effective where explosion proofing is not required.
