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;
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.
