Description - Proximity Transducer

330880-28-15-027-00-02

This self-contained proximity probe system integrates a 3300 XL 8 mm probe with a built-in Proximitor sensor inside a rugged, IP66-rated PPS housing. Part number 330880-28-15-027-00-02 is specifically configured for multi-approval (hazardous area) applications, includes a 1.5-inch standoff adapter, and provides 2.7 inches of probe penetration without additional fittings or mounting threads. It eliminates the need for extension cables and separate Proximitor housings, making it ideal for severe environments such as turbines, compressors, and large rotating machinery with shorter casing wall thickness.

FAQ - Proximity Transducer

330880-28-15-027-00-02

Q: What approvals does the “28” option include?
A: Multiple Approvals including cNRTLus (Class I, Zone 0/2; Div 2), ATEX (Ex ia IIC T4/T5 Ga), and IECEx. Suitable for global hazardous area installations.

Q: What is the difference between this model (027) and the 048 model?
A: The "C" dimension (probe penetration) is 2.7 inches vs 4.8 inches. This model is for shallower casing walls or applications where less probe stick-out is required.

Q: Do I need an external Proximitor or extension cable?
A: No. The Proximitor sensor is integrated inside the housing cover.

Q: Can I adjust the gap after installation?
A: Yes. The threaded sleeve allows ±12.7 mm (0.5 in) adjustment from the mid-setting.

Q: Is this suitable for steam or hot water exposure?
A: Brief exposure (≤1 week) to 95°C water/steam is acceptable. Longer exposure may reduce housing strength.
