Keller's ultra-compact pressure sensor for OEM with I2C output, 4LD to 9LD.
Ultra-small pressure sensor for OEM from φ11 with I2C interface.
The LD series pressure sensors utilize proprietary chip-in-oil technology. They are all-in-one sensors that house the measurement cell, digital temperature compensation circuit, and signal processing circuit in a compact housing made of stainless steel or Hastelloy. With excellent environmental resistance, they output highly accurate measurement results as digital signals (pressure and temperature information). Featuring an I2C interface and a low supply voltage specification of 1.8 to 3.6V, they are easy to integrate into microcontroller-based systems. The LD series, with its very low power consumption and digital output, is ideal for battery-operated devices and IoT solutions. **Features** • Ultra-low power consumption, perfect for battery-operated applications • Sealed and protected sensor electronics - extremely resistant to environmental influences • Ultra-compact and robust housing made of SUS (Hastelloy C-276 available as an option) • No external electronics needed for compensation or signal processing • High precision, excellent long-term stability, no hysteresis • Easy integration into microcontroller-based systems • High flexibility in use due to the pressure sensor part and signal processing electronics being handled by two chips
