Key Features & Benefits

• Integrated DC-DC converter

Provides galvanic isolation between the sensor current loop and the 12 V supply voltage

• Precision, zero-drift programmable gain amplifier (PGA)

Selectable gain values:
0.125, 0.172, 0.25, 0.344, 0.5, 0.688, 1, 1.375, 2, 2.75, 4, 5.5, 8, 11, 16, 22, 32, 44, 64, 88, 128, 176 V/V

• 16-bit DS analog-to-digital converter (ADC)

Input current cancellation

• Bandgap reference with:

Very high accuracy

Low thermal drift (max. 10 ppm/°C)

• 1K-bit EEPROM

For storing calibration and adjustment data

• 3 switchable LEDs

Colors: Blue, Orange, Red

Serve as optical indicators for different hydrogen levels

For operation of PGA-ADC 3.4, an additional "Switchable Bipolar Power Source" SBPS-LDO 3.12 (together with an included 12V plug-in power supply) and a package of 1-wire-bus stick, two 6p6c-RJ12 cables, USB memory stick with all librariers and the software) is required. The evaluation kit is operated through a 1-wire bus connector with a personal computer, an installed LabVIEW® runtime and the SensorControl software.
