Definition
At sea level nominal atmospheric pressure is 1013 mbar.
This value is used as reference for pressure measurements. This value varies according to the altitude.

Definition of atmospheric pressure :

In a given place, it is equivalent to the weight per area unit of the air column above this area. The official international unit is Pascal. The atmospheric pressure varies according to the location and the altitude where we are. On average, at the sea level, it is 1013 hPa.

  1 bar = 105 Pa = 1000 mbar = 750,25 mmHg = 14,23 Psi, 1 hPa = 1 mbar

Pressure is the ratio strength/area:
1 bar = 1 daN = 105 Pascal/cm²

Pressure Gauge :

    Sensor of pressure level. It sends out a signal when the preset threshold is reached. It can be used only with dry gas. Used on all pneumatic networks, mainly on compressors and pressure reductors.

SAPELEM pressure gauge is the only one of the market to offer additional functions such as:

• Drive two independent inlets
• Drive an outlet to regulate pressure level (compressor driving)
• Drive a temporized outlet
• Self-regulation stop and restarting automatically computed

Thus it can be used directly to drive a pressure regulation.

Handling pen :

    Handling of tiny parts without direct contact with hand. Light and handy to use.

Blow spray nozzle with directional air jet :

    Allows accurate impact and stronger blow thanks to the convergent conic air jet.
    Very efficient noise level reduction.


Inflatable finger :

    Light and hollow products’ handling. Temperature and abrasion resistant. Long lasting and cheap.

Pneumatic horn :

    Sonorous signal from a pneumatic supply.
