The Columbia Series 957 Integrated Dynamic Pressure Gage is designed for the measurement of dynamic pressure events, such as explosive blasts and high level pressure pulses, in the frequency range of 1 Hz to 15KHz. The pressure sensing area will sustain continuous operating temperatures up to +500 degrees F. Sufficient cooling must be provided such that the connector area will not exceed +280 degrees F.
The sensors are machined from Series 300 Stainless Steel, utilize a stainless steel hermetic connector, and are of all-welded construction. The integral electronic buffer provides a low impedance output when used with constant current sources of 2 to 20 mADC. Consult the factory for customized versions of this sensor.
Unit must be powered with 2 To 10 mADC current source having a compliance voltage of 18 to 30 VDC
