MPa

Description
Liquid medium sealed type pressure gauge with the pressure receiving
part to be installed into a part of pipeline.
Pipeline

Application
Ideal for the pressure measurement of pipeline in the food,
pharmaceutical, cosmetics, semiconductor and biotechnology-relatedindustries.

Features
1. No dead space
The pressure receiving part is a part of pipeline, providing no obstacles
to the liquid flow and residue in the line.
2. Hygienic inside
The pressure receiving part is hygienic since the surface is finished byClass 1-buffing on SUS316.

3. Easy to clean
To clean the inside of pipeline, it is possible to clean completely without
removing the product.

For flange installation type, enter the nominal
flange size and the lead length for capillary type.

4. Harmless medium liquid
Medium liquids are safe and harmless to health even if used as foodadditives.

Example:Installation type: Flange
Installation: Capillary type, lead length: 1m
Pressure range: 0〜1MPa
Flange JIS10kgf/cm2
In the case of 1inch
Therefore:
871-BVx1MPa, lead length: 1m
Flange JIS10K1B

5. Absorption of pulsation pressure
In the case of measurement condition with pulsation, the damper isinstalled inside to stabilize the pointer movement.
6. Wide operating temperature range
Can be used in a wide temperature range from -10°
C to +100°C.
