NAGANO KEIKI BL Process Industrial Pressure Gauges
Made in Japan
Manufacturer: NAGANO KEIKI
Model: BL
The bourdon tube pressure gauge is offered and made by JIS B 7505-1. The gauge is easy to handle with its structured simplicity with an elastic measuring element (bourdon tube) into a deflection caused by applied pressure change transmitted to a rotary geared movement-carrying pointer. It applies to a variety of applications offering wide varieties of pressure ranges. Pointer, and is easy to handle because its construction is simple. Also, wide pressure range measurements are performed and it is used in a wide range of fields.
Features
- Can be used under rain, frost, etc. conditions by adoption of sealed case. (JIS C 09220 IP43 equivalent)
- Verification standard inspection mark (Type Approval) can be attached (Depending on size, precision and pressure range).
- Available in many standard pressure ranges and can accommodate demand for use with corrosive media.
- ＊To maximize performance, select full-scale pressure range as normal operating pressure range which comes to conditions below:
For constant pressure
The maximum operating pressure should not exceed three-quarters of the full-scale range.
For fluctuating pressure
The maximum operating pressure should not exceed two-thirds of the full-scale range.
Select proper wetted parts compatible with the process fluid (gas and liquid) to which the gauge will be subjected.
Please refer to JIS B 7505-1 for details.
＊Please select “Use no oil” to use the gauge on oxygen service.
