VIBtransmitter VT1002DK/DS/DP - Modules for reciprocating compressors monitoring

The VT1002DK, VT1002DS and VT1002DP modules are specially modified versions of the VT1002D module, which are designed for condition monitoring of reciprocating compressors. Their design takes into account the specific nature of work of this type of equipment, and allows for better monitoring, then with the standard modules. Additionally, the parameters of the modules can be individually adjusted for a specific model of a compressor.

VIBtransmitter VT1002DK is equipped with specially designed analog circuit, which takes into account large pulses associated with the work of the compressor.

VIBtransmitter VT1002DS measures the vibration in intervals, which are fractions of the full work cycle of the compressor. This allows to distinguish the vibration coming from piston strokes, valves operation and other phenomena associated with the operation of a reciprocating compressor.

VIBtransmitter VT1002DP is a module dedicated to work with the proximity vibration sensors (eddy current). Additionally, the module has a feature to calculate average value of an estimate, synchronized with the phase maker.
