Integrated temperature probe calibration principle

Integrated temperature sensor calibration principle is to use thermocouple millivolt signal generator generates an analog values corresponding to different temperatures millivolt signal as an input signal transducer; use precision resistance box to generate corresponding to different values of the resistance temperature signal as the input signal of the sensor by adjusting potentiometer response, manual fuel transfer pump , in order to achieve the zero and span adjustments and accuracy of sensor calibration.

Integrated temperature sensor calibration considerations, should pay attention to the wiring polarity, and energized warmed up for 15 minutes after the start tuning. Adjust to the slow speed of the input signal, in order to ensure no overshoot. Do not use excessive force when adjusting potentiometer prevent bad twist. Before adjustment, gas station management software to be ready to check record list, and check the temperature of each thermocouple data checkpoin/ millivolt table or RTD temperature / resistance table, you will need to identify and fill in the already prepared data records in the table.

Integrated Temperature Probe Calibration Notes

Integrated temperature sensor become increasingly customer favorite, mainly because of its easy installation, accurate measurement, integrated temperature sensor can generally be divided into three types: one is the DC signal Vi is converted into a linear 4 ~ 20mA DC current or 1 ~ 5V DC voltage DC millivolt output temperature sensor, storage tank calibration methods and the other two are respectively fitted with a thermocouple and thermoelectric rent, and the temperature signal t into a uniform linear 4 ~ 20mA DC current signal I.

And 1 ~ 5V DC voltage signal V. The output of thermocouple temperature sensors and RTD temperature sensors. No matter what kind integrated temperature sensor in the factory when all must be calibrated, portable fuel transfer pump ，calibration requires specific attention to those matters it?

Can ordinary centrifugal transfer gas ?

Centrifugal impeller is rotated and the water use of centrifugal movement to occur work. Before starting the pump,gas transfer pump must be filled with water suction pump casing and the inner tube, and then start the motor, so that the shaft drives the impeller and water to make high-speed rotation, centrifugal movement of water occurs, thrown to the outer edge of the impeller,hydraulic piston pump the volute casing pump flow Road inflow pump pressure water line.

The basic structure of the centrifugal pump is composed of six parts,respectively impellers, pump, pump shaft, bearings, seal rings, stuffing box. So ordinary centrifugal pump can transport gas it? The answer is no. This is because as ordinary centrifugal blade is thick airfoil does not apply to transport gas.

The direction of rotation is not right,submersible fuel pump tightness worse, can not for the transmission of gas. Leaves transporting gas is generally thin and narrow, curved and twisted airfoil.

HTF large pump noise Cause Analysis

Conducting oil mechanical pump, heat pump noisy mainly due to bearing damage or thermal oil circulation pump cavitation phenomena due to high temperatures and thermal oil pump vibration generated support causes of instability caused due to long-term contact HTF pump operation, users use during the course of the oil bearing chamber is not changed frequently, resulting in long-term high-speed bearing long-term operation in the case of poor lubrication conditions caused by thermal oil pump bearing failure, which is conducting oil pump noise. HTF pump should be maintained on a regular basis in daily production, cleaning, the timely replacement of the bearing housing to the bearing lubrication oil. Once the bearing is damaged bearings should be replaced to avoid damage to the pump to produce other components. in addition, the newly installed clients in the use of thermal oil pumps are often used for the first temperature rise too fast or oil rise too high. This will cause HTF produce gas in the pipeline, will instantly explode when these gases in the process of conducting oil pump delivery cycle by conducting oil pump, so when conducting oil pump noise. HTF pump should be used for the first time, the oil should rise slowly and start conducting oil pump, gradually open the inner pipe vent pipe cleaner exhaust gas after the official use thermal diesel hand pump. Yet another is conducting oil pump is installed and export pipeline is not marked anchor or anchor cause instability when using thermal oil pump generates a huge pipe resonance, it will generate noise. it should be a solid pipeline of timely support. I have many years of conducting oil pump production history, production specifications, product safety, long service life can be for the majority of thermal oil pumps provide customers with strong technical guidance free of charge. welcome customers to buy our products conducting oil pump.
