Beidou Instrument Petroleum Condensation Point Online Testing System

Purpose:

Online analysis of liquid pour point, cloud point, freezing point, and freezing point.

?Measurement principle:

This instrument is based on the principle of cold mirror measurement. The probe consists of a cold pump and a mirror surface located on its cold side, and the temperature sensor is embedded in the mirror surface; The heat generated by the third and fourth stage cold pumps is dissipated through heat pipes and fans. The optical reflection system composed of a light-emitting tube and a receiving tube detects the condensation state. By detecting the light signal, the refrigeration current is closed-loop controlled to maintain the condensation state and achieve continuous detection. The temperature sensor directly measures the condensation point temperature. Analysis standards: ASTM D 5949, SH/T 0771-2005 Chinese National Standard.

?Product features:

lMeasuring the condensation point is more direct and accurate than other principles, and can avoid errors caused by inertia and hysteresis

lThe system is very stable and does not require recalibration for long-term use

lMeasure balance indicator. Capable of self judging the measurement process and indicating whether the measurement is balanced
