PIEZORESISTIVE ABSOLUTE PRESSURE SENSOR Model 8530B
Model Endevco 8530B 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 300 mV with high overload capability and high frequency response. It is available in ranges from 200 psia to 2000 psia.
- Measurement Range: 200, 500, 1000 and 2000 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)
