SIEMENS датчиков давления

Pressure Sensors

for neutral and slightly aggressive liquids and gases

• High-precision measuring
• Measuring range 0 to 60 bar relative
• Supply voltage AC 24 V / DC 12...33 V or DC 7…33 V
• DC 0 ...10 V or DC 4…20 mA output signal
• Measurement unaffected by changes in temperature
• High temperature stability
• Connection: external thread G ½", inside thread M5
• Maintenance free thanks to outstanding long-term stability
• High overload resistance
• Robust and compact construction

Use

The pressure sensors are suitable for the measurement of relative pressure in HVAC plant, particularly in hydraulic and pneumatic systems using liquid or gaseous media(steam applications).
