Installation Notes

Mount probe using M10x1 thread. Apply recommended torque of 11.3 N·m (100 in·lb), not exceeding 33.9 N·m (300 in·lb). Set initial gap to 1.0 mm (40 mils). Use 3-conductor shielded triad cable for field wiring (16-24 AWG), max length 305 m. Maintain minimum shaft diameter of 30 mm (1.2 in) for X-Y configuration. Ensure temperature does not drop below -34°C (-30°F) to prevent pressure seal failure.

Engineering Advantages

NSv design enables measurement in tight installation spaces where standard 5mm and 8mm probes cannot fit. Enhanced side-view characteristics and small target capability support shafts as small as 30 mm. Higher chemical resistance than 3300 RAM probes allows use in process compressor applications. TipLoc and CableLoc technologies ensure reliable cable attachment. Direct replacement for 3300 RAM and 3000/7000-series 190 systems.
