PORE PRESSURE TRANSDUCER
It is a good reliability electronic device used to measure pore
pressure. It requires a de-airing block. Every transducer must be
connected to the automatic data acquisition system mod. S334
(see p. 559) or mod. S301-05 ( see p. 544).
- Input voltage: 10 volts dc, Sensitivity range: 2 - 4 mV/V
- Accuracy: 0.15 fs
- Pressure connection: 0.25 BSP
- Protected against corrosive pore water pressure
- 2 metres cable and 5 pin plug included

2 CHANNELS UNIT FOR PORE
PRESSURE MEASUREMENT
Based on a high resolution graphic display this instrument allows
continuous control and monitoring of pore pressure measurements
coming from pressure transducers.
Models like S336-50 or S336-51 supplied along with proper connection
cable can be plugged into this new S356N readout so that
manual triaxial tests can be performed without need of automatic
data acquisition units or outdated mercury manometers.
S356N unit allows real time visualization of the pore pressure
measurements and subsequent peak data recording through its
dedicated peak function.

ACCESSORIES for S356N
NEW
- Pressure transducers, available models see p. 549
- De-airing block
- Extension cables for transducers
Note: It is recommended to use not more than 10m of
extension cable to avoid noise problems that
might occur.
