I.Overview
For your convenience and to ensure that you can fully grasp the functions and features of this instrument, please read the instruction manual carefully. Please keep it in a convenient location for future reference after reading.
This instrument is designed and manufactured by the national standard GB/T 8017 "Vapor Pressure Measurement Method for Petroleum Products (Reid Method)" and the American Society for Testing and Materials Standard ASTM D323-82 "Vapor Pressure Measurement Method for Petroleum Products (Reid Method)" to measure vapor pressure of gasoline, volatile crude oil and volatile petroleum products.
The Reid vapor bombs equipped on the instrument are made of stainless steel and have good sealing performance. The diameter of the pressure gauge is 150MM, and the range is 0~100Ka and 0~200Ka. The water bath tub is made of stainless steel and has excellent corrosion resistance. Electric heater is used for heating, with digital display and automatic temperature control. Its basic structure and technical conditions in line with the requirements of GB / T 8017 and ASTM d323 standards, and it is easy to use, reliable and highly precise

Description |
Initial value |
| RE |
Proportional control reset |
-99(99.9)~100(100.0)ºC |
The proportional control is reset, and when I=0, it can adjust the static difference of the proportional control instrument. |

| rt |
Process value deviation |
-99(99.9) ~100(100.0)ºC |
Used to correct measurement errors caused by sensors or thermocouple wires |

| Df |
Insensitive area |
0.4~100.0ºC |
Located in the insensitive area of the control, when P, D=0, it adjusts the dead zone of the position control instrument |
0.4 |
| AL |
Alarm point setting |
-100.0~200.0ºC |
Alarm point setting, when AL>0, it is the upper limit alarm, and when AL<0, it is the lower limit alarm. |

| P |
Proportional band(heating side) |
0~300ºC |
Proportional action adjustment, the larger P is, the smaller the proportional effect is, the system gain is at least low, only on the heating side, and P=0 is the position control. |

| I |
Integration time
(re-adjust time) |
0~3600 second |
Integral action time constant, the larger I is, the weaker the integral action, the PD control when I=0 |
240 |
| D |
Differential time
(pre-adjustment time) |
0~3600 second |
The larger the differential action time constant D is, the stronger the differential action is, and the overshoot can be overcome, and the PI control at D=0 |
