    FAQs

    Q1: What is the primary function of the 21000-28-05-00-085-03-02?

    It is an external probe housing assembly that provides mechanical protection, precise alignment, and hazardous area certification for a 3300 XL 8 mm proximity probe. It enables external access to the probe and extension cable for gap adjustment or replacement without disassembling the machine.

    Q2: What does the "-085" suffix indicate in the part number?

    The -085 indicates a probe penetration depth of 8.5 inches (216 mm). This is the length of the probe sleeve that extends into the machine housing to reach the measurement location. The adjustment range is typically ±0.5 inches (13 mm).

    Q3: What is the difference between the 21000 and 24701 housing assemblies?

    The 21000 uses an aluminum body with a 304 stainless steel sleeve (weight: 1.1 kg typical). The 24701 uses a 303 stainless steel body with a 304 stainless steel sleeve (weight: 1.8 kg typical), making it more suitable for corrosive environments.

    Q4: What hazardous area certifications does this housing hold?

    The 21000 housing is CSA Type 4 certified and rated explosion-proof for Class I Divisions 1 and 2 Groups C and D, Class II Divisions 1 and 2 Groups E, F, and G, and Class III. It is also compliant with API 670 for externally mounted proximity probe housings.

    Q5: What is included in the fittings option "-03"?

    The -03 fittings option includes: one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and one cable seal grip with grommets for cable sizes of 1/8 to 3/16 inches, 1/4 to 5/16 inches, and 5/16 to 3/8 inches.
