The 330750 and 330752 High Temperature Velomitor System sensor head and integral cable are designed for hightemperature environments. This enables you to mount thesensing head on surfaces with temperatures up to +400°c(+752°F)

To accomplish this, the transducer design segregates thesensing element from the signal conditioning electronics. Thetwo are permanently connected using an integrated cable.The integrated cable eliminates connectors which are asignificant source of transducer failures.

The cable enables you to position the signal conditioningelectronics in a cooler location. The internal electronicswithstands temperatures of 55°C to +121°C (-67°F to +250°F).The integrated design makes it possible to capturemachinery performance data comparable to other BentlyNevada Velomitor transducers, but at significantly highertemperatures.

Frequently Asked Questions

What is the primary function of the Bently Nevada 330752-25?

It measures casing and bearing housing absolute vibration on high-temperature machinery.

What does the "-25" signify in the part number?

It indicates the specific integral cable length, measuring exactly 2.5 meters (8.2 feet).

What is the maximum operating temperature for the sensor head?
