The Future is Digital

Series 4 LD…9 LD

With I2C interface and Embedded Signal Conditioning


With the D-line, Keller introduces a unique combination consisting of an exceedingly robust industrial pressure transducer and the popular I2C microcontroller interface. Pressure transmitters with this interface are commonly available only in consumer market housings made of plastic or ceramic, where merely the parameters for compensation are stored in an integrated memory. The D-line OEM transmitters however have an unprecedented embedded digital signal processing (DSP) core for the compensation and normalization of the output values.


Performance features:
• Ultra low power consumption, optimised for battery powered applications
• Hermetically protected sensor electronics – extremely resistant to environmental influences
• Ultra-compact, robust housing made from stainless steel (optional Hastelloy C-276)
• No external electronics for compensation or signal processing
• Extremely accurate, outstanding long-term stability, no hysteresis
• Pressure ranges of 1 bar to 1000 bar
• Easy to integrate into microcontroller based systems
• Internal two-chip solution with pressure sensor and signal processing separation provides a high degree of flexibility
