Description：

The 3300 NSv probe comes in varying probecase configurations, including armored andunarmored 1/4-28, 3/8-24, M8x1 and M10x1probe threads. The reverse mount 3300 NSvprobe comes standard with either 3/8-24 orMl0xl threads. All components of thetransducer system have gold-plated brass ClickLoc connectors. ClickLoc connectors lockinto place and prevent the connection fromloosening. The patented TipLoc moldingmethod provides a robust bond between theprobe tip and the probe body. Bently Nevada's patented Cableloc design provides 220 N (50Ib) of pull strength and securely attaches theprobe cable to the probe tip. Connectorprotectors are recom mended for use on theprobe-to-extension cable connection, as wellas on the cable-to-Proximitor Sensorconnection. Connector protectors prevent mostliquids from entering into the ClickLocconnectors and adversely affecting theelectrical signal(2).

Notes:

(1) Proximitor Sensors are supplied by defaultfrom the factory calibrated to AlsI 4140 steel.Calibration to other target materials is available upon request.

(2) Silicone tape is also provided with each3300 NSv extension cable and can be usedinstead of connector protectors. Silicone tape isnot recommended in applications where theprobe-to-extension cable connection will be exposed to turbine oil.
