Relative pressure transducer SMART SN

4-20 mA2-wire3-wire

Smart SN Microprocessor supported pressure transducers are robust, microprocessor supported electronic pressure transducers in the Smart SN series from Honeywell FEMA measure relative pressures in ranges from -1 …+1 bar and 0-40 bar. They are particularly suitable for use as pressure sensors in the fields of mechanical engineering, supply engineering, environmental technology and HVAC. The equipment can be installed directly in the pressure line using the G1/2" external thread. Entering switching points is easy with the generously proportioned keyboard and graphic display. 2- and 3-wire versions are available, as are versions for use with alternating current. Note: Cycle time: 100msec Pressure surges shorter than the cycle time of 100 msec are not written in the peak values. Remedy for pressure surges can afford a front mounted pressure surge reducer DMW. Features & Benefits: Restore function Warning function for sensor fault, overload and overheating Manual zero adjustment · 4-digit code enables locking Smart SN display functions Current pressure display · Current analog output display (voltage or power) WARNING - Display with visible error codes · Rotation of graphics display in 90° steps, possible by means of software Certifications: All 2-wire versions are SIL2 approved according IEC 61508
