Isolated Stainless Steel OEM Customized Welcomed Accurate Differential Pressure Sensor
1. Product Description:
HPT708 DP Transmitters are consisting of differential pressure sensor, process pressure room, smart digital signal circuit board and stainless steel housing.
For Oxygen services application, transmitters need doing degreasing as following steps:
- Degreasing for DP sensor(filled Halocarbon oil inside)
After finished differential pressure sensor manufacture and testing for performance, stability and integrality. We will beginning the first time degreasing for this pressure sensors.
First, we will use nitrogen blow the surface of sensor, then use alcohol clean diaphragm and stainless steel body and dry it, then immerse sensor into degreasing solvent just keep top electronic wires outside solvent(because before manufacturing sensor, all spare parts passed degreasing). Sensors immerse to degreasing solvent about 3 to 4 hours total and each 5 to 10 minutes turn back and forth and left and right. Keep sensor surface completely degreasing.
The next step is centrifuge dripping sensor and use absorbent cotton clean, then nitrogen blow the surface of sensor again and alcohol clean diaphragm and stainless steel body again.
2. HPT708 Process pressure room and stainless steel housing degreasing
- Process room and housing clean before machining.
- Process room and housing clean after machining.
Above two steps clean are use the same degreasing solvent and alcohol.
3. After assembling HPT708 DP Transmitters, clean the completed products
- Before clean the completed transmitters, we will use gas for calibrate the transmitters.
Then we will clean dust use water and then dry transmitters.
- After calibrated well transmitters and we will put transmitters immerse degreasing solvent 2-3 hours for third time degreasing oil. And repeat the clean steps.
- After above clean and degreasing, the transmitters will be very clean and nice.
Then we do temperature compensation for lower and higher temperature environments.
After 48 hours temperature compensation, the next step is inspection before packing.
If inspection data is correct and accuracy, then we will use nitrogen blow the surface and process holes. Then we will cover the red color blind plug and use clean plastic bag for seal transmitters.
