The P44000 is a high-isolation temperature transmitter designed for monitoring Pt100 sensors in high-voltage hydrogen applications. With continuous insulation up to 6.6 kV AC/DC, it ensures safe and accurate temperature measurement in electrolyzers and fuel cells, where isolation integrity is critical. Available in multiple ranges and compact housing options, it delivers reliable 4...20 mA output signals even under extreme environmental conditions.

Designed for safety and performance, the P44000 supports 2-, 3-, and 4-wire Pt100 inputs and offers selectable ranges (0–150 °C, 0–200 °C, or 0–300 °C). Its fast 100 ms response time make it ideal for real-time temperature monitoring of stacks, strings, and cell grouping. The device can also take a wide range of power supplies (22–230 V AC/DC) ensuring stable operation in demanding installations.
