Hydrobar-I

Precision pressure transmitter with HART protocol adjustment and full ATEX/IECEx compliance for hazardous environments.

The Hydrobar-I delivers 0.1% accuracy across a 0.04–10 bar range with integrated microprocessor intelligence and remote configurability via HART protocol over standard 4-20 mA signal lines. Engineered for intrinsic safety in classified zones (ATEX Ex-ia, IECEx Ex-ia, EAC Ex-ia), it combines corrosion-resistant AISI 316L construction with optional Hastelloy C, Tantalum, or gold-plated diaphragm materials for aggressive media. Wide process temperature tolerance (-10 to +70°C), multiple connection options, and full SIL2 functionality ensure reliable level and pressure monitoring across maritime, sanitary, and industrial applications.
