PCB-137B32
Quartz, free-field, ICP® blast pressure pencil probe, front sensor is 250 psi, 20 mV/psi, rear sensor is a placebo, 4-pin connector
This 2-channel pencil probe features our highest resolution sensing element in the front location and a placebo gage in the rear location; perfect for close in measurements and detecting error sources at the same measurement point.- Measurement Range: 250 psi (1724 kPa)
- Sensitivity: (±15%)20 mV/psi (2.90 mV/kPa)
- Resonant Frequency: >=400 kHz
- Electrical Connector: 4-Pin
- Weight: 16.1 oz (456 gm)
