- Original Factory Genuine, Tenfold Compensation for Counterfeits
- Full Machine Warranty, Lifetime Maintenance
- In Stock, Shipped on the Same Day
The BG type is a plain-bar thermowell with a simple structure and low cost, recommended for non-pressurised applications; not recommended for pressurised applications and strictly prohibited for hazardous media. Two base types are available: integral (01) and steel-tube (03), with four mounting options: without fixing device, ferrule thread, ferrule flange, and loose flange, suitable for various thermocouples, resistance temperature detectors and bimetallic thermometers. The thermowell total length must meet the minimum length requirement according to the mounting method.
