Keller OEM Series 4LC / 9LC Piezoresistive OEM Pressure Transmitters (with embedded signal conditioning)

The Series 4 LC to 9 LC is characterized by having fully integrated compensation and signal standardization over the entire temperature range from -40  to 150
Technology
KELLER grew up in the 1970s with OEM pressure transducers. Now the company has not only outstanding know-how in design, connection and housing technology at it disposal. After many years of experience in digital signal processing, KELLER has integrated signal processing and compensation at chip level in a joint, hermetically sealed housing in a top class OEM transmitter in the Series 4 LC to 9 LC. First, the entire transmitter electronics in the transducer housing are hermetically embedded in oil and second, these highly-integrated OEM transmitters represent an ideal pressure transmitter module for integration in higher-order systems due to the selected analogue and digital output signals. Interfaces The ratiometric, analogue output signal makes connecting to an external analogue/digital converter extremely simple: the fact that both systems are in principle referenced to each other means that there is no need to set up an expensive, absolute measuring system.
The CIO pressure transmitters are designed for 5 V applications, and also provide constant protection against overvoltage and polarity reversal on all lines up to !à33 VDC. Faraday encasulation makes them extremely EMC resistant.Performance features.
