The differential pressure sensors USD50 with piezo resistive sensor and welded metal membrane are used in process and environmental industries. They measure level, volume and mass in liquids as well as differential pressure in e.g. filters and pumps as well as in flow applications (volume and mass flow).
Silicon differential pressure sensor, uncompensated bridge output signal with cable connection.
Measuring range 10mbar to 40bar
Bridge output signal (mV/V)
Highest accuracy, reproducibility and long term stability
High overload resistance of 160/420*bar (one side) 240/630bar* (both sides)
For measuring ranges from 100mbar a higher overload range is optional:
420bar (one side), 630bar (both sides) optional
Output signal and energy supply:
Recommended: Constant current feed, <1mA
Bridge resistance: 4.3…5.6kΩ (25°C)
Output signal: 22…55mV/V (span)
Ø 55 mm x 40 mm
Ambient/process temperature: -40 to +85°C
Storage temperature: -40 to +85°C
The differential pressure sensors are the base for the design and construction of high quality differential pressure transmitters. The sensors are uncompensated and can be compensated and calibrated at customer site.
