| Keterangan: | 330525 Velomitor® XA Piezo-Velocity Sensor
Brand : Bently Nevada
Piezo-Velocity Transducers System
This is an environmentally hardened version of our 330500 Velomitor® piezoelectric transducer, and is designed to meet NEMA 4X and IP65 ratings without the use of a housing. The piezoelectric sensor' s mounting stud uses pipe threads and does not require the transducer base to be flush with the machine case. This eliminates special mounting surface preparation required with other velocity transducers, resulting in lower installation costs.
