In response to your inquiry I would like to inform you that in January 2016 Udmurtneft purchased four ТСМв-1388-02-1500С-50М-В4-С10 ТУ 4211-036-39375199-11 resistance temperature detectors manufactured by NPO Vakuummash for pilot operation.

These RTDs were installed on process pumps of the сentral oil system. The ambient temperature at the working places is -40…+40 degrees, the temperature of the measured parts of the equipment is up to +100 degrees.

During the pilot operation from January 2016 to the current moment, the RTDs have shown their reliability (no failures were recorded), stable performance and stable measuring characteristics.

Based on the above, we believe that the products of NPO Vakummash can be used in control systems at similar facilities in the oil industry.
