1 EPI 887 Industrial Pressure Transmitter Swiss based Trafag is a leading international supplier of high quality sensors and monitoring instruments for measurement of pressure and temperature. The industrial pressure transmitter EPI 887 features the extremely robust and stable thin-film-on-steel sensor element from its well-proven predecessor EPI 897. In combination with the new inhouse developed ASIC TX it offers a wide temperature range up to C and triple overpressure safety which makes it the perfect solution for a wide range of demanding applications. Applications Machine tools Hydraulics Industrial applications Features Excellent long-term stability High resistance to over pressure Completely welded steel sensor system without additional seals Compact design Different accuracy classes Data sheet H77h 08/07 Technical Data Measuring principle Thin film on steel C typ. ± 0. % FS typ. ± 0. % FS typ.
