FUNCTION
The TR-NC/8 transmitter makes the following measurements:
-
VB: Vibration (relative) of a rotor respect to its support
-
AX: Displacement (axial) of a surface with respect to a fixed point, differential
displacement between two points.
- PH: Phase reference
The measurement is made by the correct positioning of a no contact sensor in the
vicinity of the point to be measured (made of ferrous material); the transmitter
supplies an output signal suitable for an acquisition system based on the two-wire
technique (current loop 4 to 20 mA).
The transmitter is certified for applications in areas classified as:
- Ex II 1 G Ex ia IIC T5
- Ex II 1 G Ex ia IIC T6
