100mm Dial Stainless Steel 10 bar Precision Pressure Gauge for Hazardous Environments
Description
The helical Bourdon tube has several turns winded into a helix. The number of coils can vary from two or three to as many as twenty. They can be equipped with or without a transmission mechanism. The pressure gauge is a traditional bourdon tube type unit, but designed specially for hazardous environments such as mining and quarrying.
Applications
For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive environments
Precision measurement in laboratories
High-accuracy pressure measurement, testing of industrial type pressure gauges
Increased safety requirements for personal protection
With liquid-filled case for applications with high dynamic pressure loads or vibrations
Special features
Safety pressure gauge with solid baffle wall designed in compliance with the requirements and test conditions of EN 837-1
Completely from stainless steel
Knife edge pointer for optimal accuracy of reading
Wear-resistant precision movement from stainless steel
Scale ranges from 0 … 0.6 to 0 … 1,600 bar [0 ... 10 psi to 0 ... 20,000 psi]
