PIEZORESISTIVE ABSOLUTE PRESSURE SENSOR Model 8530С
Model Endevco 8530С is a miniature, high sensitivity piezoresistive pressure transducer for measuring absolute pressure. The volume behind the diaphragm is evacuated and glass sealed to provide an absolute pressure reference. Full scale output is 225 mV with high overload capability and high frequency response. It is available in ranges from 15 psia to 100 psia.
- Measurement Range: 15, 50 and 100 psia ranges
- Mounting thread: 10-32 UNF-2A threaded
- Temperature: -65˚F to +250˚F (-54˚C to +121˚C)
- Weight: 2.3 grams (cable weighs 9 grams/meter)
