973
- High Pressure
- Low Output Impedance, Wide Frequency Response
- Electrically Isolated
- Corrosion-Resistant
- Compact Size
The Model 973 High Intensity Pressure Transducer is designed for the measurement of dynamic pressure events, such as explosive blasts and highlevel pressure pulses in the frequency range of 2 Hz to 18KHz. This unit is designed for use in the most corrosive environments.
The unit is housed in a rugged stainless steel housing and incorporates a hastelloy diaphragm. The stainless steel MIL-style connector combined with the all-welded construction provides a true hermetic seal. The sensor's integral electronic buffer provides a low impedance output when used with constant current sources of 2 to 10mADC. Consult the factory for customized versions of this sensor.
Notes:
Unit must be powered with 2 to 10 mA DC Current Source having a compliance voltage of 18 to 30 VDC. Unit is Hermetically Sealed.
