IKV-1-3-1 vibration measuring channel cryogenic version

IKV-1-3-1 vibration measuring channel cryogenic version

The indicator is designed to measure vibration displacement span, rotational speed, axial shift and detecting marks in vibration monitoring systems of rotary machines at low temperatures;

It consists of a DS-1 eddy-current transducer and AV131-V converter (in the connecting box).

Output signal type – 4...20 mA, 0...10 V, digital Modbus RTU;

These vibration transducers are tuned to a specific temperature and a specific metal according to customer requirements.
The operating temperature range of the vibration transducer relative to the setting temperature is ± 30 ° C, within the range of -100 ... -200 ° C.

Example 1. To control the pump for pumping liquid nitrogen, the sensor is tuned to a temperature of -196 ° C and provides the claimed accuracy of the characteristics in the temperature range -166 to -200 ° C.

Example 2. To control the pump for transferring liquefied gas at a temperature of -154 ° C, the sensor is set to a temperature of -154 ° C and provides the claimed accuracy of the characteristics in the temperature range -124 to -184 ° C.
