Frequently Asked Questions (FAQ)

Q: Can 21000-00-00-60-028-02-02 be directly applied to the measurement points of a reverse-mount 8mm probe?
A: Yes, the internal space and interface design of this protective cover perfectly match the 3300 XL 8mm series reverse-mount probes.

Q: When using 21000-00-00-60-028-02-02, why is it unnecessary to add the original 37948-01 internal bearing housing support as with the long sleeve?
A: Because the 2.8-inch penetration length of this model is much shorter than the critical overhang length of 12 inches (approximately 304 mm), and the housing itself is rigid enough to resist machine vibration.

Q: What are the practical advantages of the "00-00" at the beginning of model number 21000-00-00-60-028-02-02, which indicates that a probe is not included?
A: Without a probe included, the "00-00" configuration allows the unit to be ordered as a pure protective housing, with later customization or replacement of internal 8mm, 11mm, or NSV probes.

Q: What is the core purpose and explosion-proof certification of model 21000-00-00-60-028-02-02?
A: This model is used to protect eddy current probes during external installation. It is made of stainless steel and has North American CSA gas and dust explosion-proof certification.

Q: In a petrochemical field, does the design of 21000-00-00-60-028-02-02 comply with the latest industry standards?
A: Yes, the design of this protective housing fully meets and complies with all the requirements of the American Petroleum Institute (API) 670 standard for externally mounted probe housings.
