 Induistrial Process Gauges from 3D Instruments are called TLG's for "Tough Little Gauge". Small wonder, our Industrial Process Gauges are designed specifically for the toughest conditions in your process.
Typically a 3D TLG can last 4-10 times longer than a standard gauge has been liquid filled. The "Tough little Gauge" is available in diameters of: 21/2", 41/2", and 6".
The 'Dyna-Mount' 41/2" TLG is standard with a special swivel fitting and moveable flange. The gauge can be changed to front or back flange and bottom or back mount (except 30 psi) in the field with no more than a screwdriver.
Standard accuracies are 0.5% mid-scale.
Pressure ranges available are from vacuum to 20,000 psi.
