OEM pressure sensors for refrigeration technology Model P3308
Standard output: 4...20 mA;
2-wire system or 0...10 VDC;
3-wire system
or 0,5...4,5 VDC; 3-wire system
Description
Robustness and
long-term
stability
during
operation are the strengths of this compact pressure sensor for refrigeration technology. The technical specifications and attractive price level of these sensors make them ideal for OEM applications.
High chemical resistance against usual refrigerants as well as condensation tightness under hardest operating conditions characterises this compact pressure sensors. Welded connections between pressure cell and process connection require no sealing elements and make the measuring system particularly resistant to mechanical shock and vibration. The compact design makes these sensors interesting for space critical applications. With a wide variety of electrical and mechanical process connections the pressure sensor provides the optimal solution to different applications in the refrigeration technology.
A protection rate IP69K can be achieved with moulded cable connection.
The pressure sensor complies with electromagnetic compatibility requirements (EMC) as per EN 61326.
