The SIGMA 90 is equipped with: 5 pressure gauges 0-15 bar, to check the output pressure of the units under test and the adjustable pressure 1 pressure gauge 0-20 bar to check the input pressure 4 pressure gauges 0-20 bar to check the tank's pressure 2 pressure gauges 0-200 bar to check pneumo-hydraulic unit's pressure The body is built with materials which make it particulary strong; on the work-table there is a swivelling vice for the fastening of the different braking units under test. It is composed by: a console board forelectrical controls high pressure fast coupling, made of stainless steel, which may be easily used vacuum circuit to check the servobrakes pneumatic control board Inside the machine bed we can find a two-stages moto-compressor with the following technical featurings; max operating pressure : 18 bar; air suction: 275 lts/min; motor power: 2,2 Kw at 2840 rpm; a cock on the compressor's suction unit for vacuum; 3 tanks capacity of 15 Lts; 1 tank capacity of 20 Lts; distributors control unit.

The test bench enables to check :

	Regulating groups
	Distributors
	Couplings
	Protection valves
	Brake cylinders
	Servo-distributors
	Vacuum servobrakes

Size : 1100 x 750 x 1660 mm
Net weight : about 350 kg
Portable case for testing the compressed air braking systems.

Simple and pratical to use, it allows to carry out in a few minutes an accurate test to identify the anomalies of the whole braking pneumatic system.
