Blondelle ‘A Lame Acier’ Principle.

Pressure-sensitive element formed of a bellow and a hardened stabilised blade.

• Class 1 accuracy: 1% of the end of the scale.
• Admissible overload: 200% for pressure gauge
• Accidental pressure: 50% for vacuum gauge
   

• Each instrument is calibrated individually.
• Perfect impression of dials through tampography provides you with high reading sensitivity.
• Light alloy casing or very high resistance injection moulded composite
   

• Operation temperature: -40°C +70°C
• Your logo can appear on the dials
• Endless combinations of refrigerants

The “ A Lame Acier®” pressure gauge comprises a pressure-sensitive element formed of a metal bellow and a steel plate.
The steel plate A describes a generating line proportional to the pressure existing inside the bellow S (bellow stituated between the two arched ends of the steel plate).
One of the ends of the steel plate is fixed to bracket R which itself is fixed to the housing at a-b.
A fork F fixed to the other end drives the kinematics, thus rotating the needle.
The adjusting screw V - accessible from the outside - enables adjusting the position of the needle.
