84661-25 | Bently Nevada Velomitor Interconnect Cable

The standard 330500 Velomitor* Piezo-velocity Sensor has a limited temperature range it can be exposed to, due to its signal conditioning electronics being located in the same case as the sensing element. Temperature limitations of the electronics limit its maximum operating temperature to 121C (250F). The 330750 and 330752 High Temperature Velomitor System (HTVS) has a fundamentally different construction to solve this problem. Its design segregates the sensing element from the signal conditioning electronics, with the two permanently connected via a hardline cable. Current versions (see note below) of these sensors allow the sensing head to be mounted on surfaces with temperatures as high as 400C (752F). Due to the segregated design, thesignal conditioning electronics can be installed in a cooler location. Thisachieves overall transducer system performance comparable to other Velomitor transducers, but permits use at significantly higher temperatures. By eliminating connections between the sensing head and its associated signal conditioning electronics, a significant source of potential transducer failures (connector problems) is eliminated.
