KFBH - 60 Chemical Plant Gas Sentinel
Introduction
Chemical Plant Gas Sentinel: KFBH - 60 plays a crucial role in chemical plant safety. It can be integrated with a gas controller for comprehensive gas monitoring. The detector features high precision with an error of <5% F.S. and excellent repeatability of ≤±1%. It supports different cable requirements for 4 - 20mA and Modbus connections. With explosion - proof protection, it’s reliable for use in chemical plants where gas hazards are common.
Product Features
1. High precision and repeatability for accurate monitoring.
2. Compatibility with gas controllers.
3. Specific cable requirements for different connections.
4. High - level explosion - proof protection.
