Keller OEM Series 9LX Low Total Error Band O.E.M. Pressure Transmitters
DESCRIPTION
Whether embedded in an OEM product or simply packaged as a high-end pressure transmitter, the Series 9LX 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 9LX features a flush-welded diaphragm and highly stable piezoresistive sensing element. Combined with Keller!ˉs advanced signal-conditioning circuitry, the 9LX 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
Programmable analog outputs enables infinite range options
Standard dual (analog & RS485) outputs simplify interface to controls, data collection, and telemetry systems 16-bit internal digital correction for cost-effective low ±0.1% Total Error Band (TEB) accuracy over
-10...80°C Factory calibrated for guaranteed
“out-of-the-box” performance. 316L SS flush-diaphragm sensor
standard - Optional titanium or hastelloy - C276 for severe applications.
RS485 modified-MODBUS compatible allows up to 128 transmitters on a single bus.
Separate output for temperature via RS485 interface.
