• Probe cable length: 10 = 1.0 m (39 in)

How Does This Housing Compare with Other Options?

The 21000 series uses an aluminum body with a 304 stainless steel sleeve. The related 24701 series uses a stainless steel housing. Both are certified as CSA Type 4 enclosures and comply with API 670 for externally mounted proximity probe housings. This unit is rated explosion proof for hazardous areas when ordered with CSA approvals.

Unlike housings that include a standoff adapter, this configuration has standoff option 00 (no standoff adapter). The mounting thread option -02 (3/4-14 NPT) must be ordered when the standoff adapter length option is not -00.

Where Is This Probe Housing Used?

This assembly suits rotating machinery protection where a reverse mount proximity probe needs a protected, explosion-proof enclosure. Typical applications include pumps, motors, and compressors in hazardous areas. The 1.0 m cable and 4.1 in probe penetration support installation in tight spaces.

What Should Buyers Verify Before Ordering?

Confirm the probe option, cable length, standoff adapter, probe penetration, fitting, and mounting thread match your system. This unit ships with a 12-month factory warranty. Contact TenBN for Bently Nevada parts pricing and availability.
