Low Cost Stainless Steel Pressure Sensor
WA19 series are based on piezoresistive silicon pressure sensors packaged in a 316L stainless steel housing. The sensing package utilizes silicon oil to transfer pressure from the 316L diaphragm to the sensing element.
It is designed for o-ring mounting for the applications where compatibility with corrosive media is required. Each sensor was strictly temperature compensated for both zero and span.
There are two options of excitation power -- current and voltage
Features - Pressure Sensor:
1. High stability and high accuracy
2. Low cost OEM
3. Suited for pressure range: 0-40Kpa-7Mpa
4. Wide temperature compensation range: total error <1%
5. Measurable of corrosive media ( media compatible with 316L)
6. Standard mounting size
7. Typical output:0-100mV
