Accurate Gauge Borehole Deep Well Differential Pressure Sensor

Accurate Gauge Borehole Deep Well Differential Pressure Sensor1. 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 3to 4hours total and each 5to 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 degreasingProcess room and housing clean before machining.Process room and housing cleanafter machining.Above two steps clean are use the same degreasing solvent and alcohol.
3. After assembling HPT708 DP Transmitters,clean thecompletedproductsBefore clean thecompletedtransmitters, we will use gas for calibrate the transmitters.Then we will clean dust use water and then dry transmitters.Aftercalibrated well transmitters and we will put transmittersimmersedegreasing solvent2-3 hours for third time degreasing oil.And repeat the clean steps.After above clean and degreasing, the transmitters will be very clean and nice.

Thenwe dotemperaturecompensationfor lower and higher temperatureenvironments.
After 48 hours temperaturecompensation, the next step is inspection before packing.
If inspection data is correct and accuracy, then we will usenitrogen blow the surfaceand process holes.Thenwe will cover the red color blind plug and use clean plastic bag for seal transmitters.
