There are many different tools that can be used for measurement, but the degree of accuracy is dependent upon the tool. For example, a ruler can measure distance with a good degree of accuracy, but for a more precise measurement a caliper should be used. The difference between a brass pressure sensor and a stainless steel pressure sensor is similar if we think about it in these terms:
WarrantyInstallation Instructions
- High-quality sealed sensor housings are virtually impervious to automotive fluids (360-degree welded wetted area)
- Brass sensors accurate to within 3% of full scale (pressure sensors)
- Analog data scaled across full 100 PSI
