cảm biến áp suất Pressure Sensor 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)
