OEM 耐壓防爆型壓電式傳送器 Series D Ei

With I2C interface for hazardous areas 


With the intrinsically safe D-line, KELLER introduces a unique combination consisting of an exceedingly robust industrial pressure transducer and the popular I2C microcontroller interface for applications in strongly hazardous areas of the gas group II (industry applications). 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 intrinsically safe 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
