PCB-123B22
Rocket motor ICP® pressure sensor 3000 psi 1mV/psi Helium bleed water-cooled (replaceable tubes)
This new sensor replaces Model 123A22. Model 123B22 features water cooling tubes that may be replaced on site without returning the entire sensor back to PCB for service.- Measurement Range: 3000 psi (20685 kPa)
- Sensitivity: (±15%)1.0 mV/psi (0.145 mV/kPa)
- Low Frequency Response: (-5%)0.001 Hz
- Resonant Frequency: >=25 kHz (>=25 kHz)
- Electrical Connector: Integral Cable
- Weight: 4.59 oz (130 gm)
Specification Notes
[1] Zero-based, least-squares, straight line method.
[2] Typical.
[3] With helium flow.
[4] Applies to internal amplifer, not to external housing.
