Safety pressure sensor DAIL
1Pages

With analog signal and switch output Safety pressure sensor DAIL The DAIL fulfils the requirements of EN 1114-1 for overpressure protection of extrusion lines and offers maximum comfort of operation. The auto-zero function enables calibration directly on the device or from the observation point/controller. On the output side, the melt pressure transmitter provides a switch output in addition to the analog signal which enables switching off the machine in case of overpressure according to EN 13849-1, PL=c. • witch output for overpressure protection S • witch-off pressure freely selectable S • nalog output mA or V A Technical specifications • erformance Level c according to EN13849-1 P • ÜV certified T Pressure range • G-coating to counteract adhesive materials Accuracy incl. linearity, hysterisis, • ompatible with common OEM sensors C and reproducibility in % to full scale • Longlife design Reproducibility in % to full scale Membrane coating Max. pressure overload without influence on operating value 1,5 x pressure range over 1000 bar (14,500 psi) Bridge resistance Supply voltage Output signal Transmission medium Process connection Calibration point Insulation resistance Max. temperature at terminal head during Product variations (examples) Auto-zero Function As an option available with optical auto-zero release in the sensor head operation Zero point deviation against diaphragm temperature changes at the diaphragm % / ° C ( % / 1,8 ° F ) Zero point deviation against temperature chan- Special diaphragm coating Special coating options available ges at terminal head in % / ° C ( % / 1,8 ° F ) Ingress protection housing Ingress protection connector * With standard diaphragm, transmission medium NTX and 1/2”20 UNF.
