Media Isolated OEM Pressure Transmitters
Product Announcement from Keller America, Inc.
The "…LY" transmitter line benefits from smaller sensor dimensions, crevice-free diaphragms and low Total Error Band performance. The innovative signal conditioning circuit 'learns' thermally-induced zero and span errors during calibration. Then during operation, bias corrections are applied directly to the analog output signal, with a resolution of 1.5°K, effectively making each correction temperature a calibration temperature.
The residual error is therefore determined primarily by the sensor nonlinearity. The "…LY" line also boasts excellent resistance to electromagnetic interference. The limits of the CE standard, for both conducted and radiated fields, are bettered by a factor of 10, enabling implementation in hostile EMI environments.
Applicability to a variety of applications is enhanced by a wide selection of pressure ranges, sensor types, and input/output configurations. Material compatibility is ensured by the optional Hastelloy C-276 construction in place of the standard 316L stainless steel, as well as several different o-ring materials.
