Keller OEM Series 30X high accuracy analog digital output pressure transmitter
DESCRIPTION
Whether embedded in an OEM product or simply packaged as a high-end pressure transmitter, the Series 30X enables the OEM to offer superior performance without the need for huge R&D or capital expenditures, and with minimum amount of on
hand inventory. Designed to be easily integrated into a wide variety of applications, the 30X features a flush-welded dia-
phragm and highly stable piezoresistive sensing element.
Combined with Keller!ˉs advanced signal-conditioning circuitry, the 30X features dual (analog & digital) outputs, re-rangeability and mathematical error correction. The result is outstanding Total Error Band (TEB) accuracy over a wide compensated temperature range.
FEATURES
