Description
DIFFERENTIAL pressure transducers Nominal pressures from 100 mbar to 15 bar AMPLIFIED outputs: ±10Volt Linearity and hysteresis 0,10%
DIFFERENTIAL pressure transmitters of these series distinguish themselves for high reliability and long-term stability of mechanical and electrical features.
The sensitive part, in contact with pressure, is entirely made of 316 corrosion-proof stainless steel.
High vacuum thermal treatments which stainless steel is subjected to, ensure the correct functioning even when dynamic stresses are involved.
Pressure is internally detected by two bridges, that guarantee the maintenance of performances even when dynamic stresses are involved.
Electronic section, realised via SMD technology, consists of a high precision instrumental amplifier and a stable supplier, protected against short circuits and polarity inversion.
Every pressure transmitter is entirely LASER welded to ensure high degree of hermetic tight.
During production cycle, pressure transmitters are thermally compensated, tested and individually calibrated with the use of completely automated stations that analyse data.
These features make their use ideal in several industrial fields, as: pneumatic, hydraulic, food process control and, generally, whenever checking the difference between two exerted pressures is necessary.

Functioning example
| Port | Pressure | 4-20 mA* | ±5 V | ±10 V |
|---|---|---|---|---|
| A + | 0 | 4 mA | 0 | 0 |
| B – | 0 | 4 mA | 0 | 0 |
| A + | FS | 20 mA | +5 V | +10 V |
| B – | FS | 20 mA | +5 V | +10 V |
| A + | 0 | max 0.8 mA | -5 V | -10 V |
| B – | FS | max 0.8 mA | -5 V | -10 V |
| A + | FS | 4 mA | 0 | 0 |
*In the version with mA output, when pressure increases in the port B-, the signal decreases down to 0.8mA then stops even if pressure continues to increase
