(linear, 4 shapes, direct
or reverse action)
21 ÷ 105 kPa (3 ÷ 15 psi / 4 ÷ 20 mA)
– working angle 0 ÷ 45°
21 ÷ 105 kPa (3 ÷ 15 psi / 4 ÷ 20 mA)
– working angle 0 ÷ 65°
21 ÷ 63 kPa (3 ÷ 9 psi / 4 ÷ 12 mA)
– working angle 0 ÷ 45°
63 ÷ 105 kPa (9 ÷ 15 psi / 12 ÷ 20 mA)

21 ÷ 63 kPa (3 ÷ 9 psi / 4 ÷ 12 mA)
– working angle 0 ÷ 65°
63 ÷ 105 kPa (9 ÷ 15 psi / 12 ÷ 20 mA)
– working angle 0 ÷ 65°
Zero suppression
0 ÷ 63 kPa (0 ÷ 9 psi)
Range adjustment 30% of the range
Air consumption
0,6 SCFM (1,04 Nm³/h) in balanced condition for standard model
with ¼” NPT F connections.
0,8 SCFM (1.3 Nm³/h) in balanced condition for special model
with ½” NPT F connections.
(with air supply at 420 kPa
– 60 psi)
Sensitivity 0,25% better than the considered signal range
Capacity (max. load)
15 SCFM (25
Nm³/h) with ¼” NPT F connections.
36 SCFM (60
Nm³/h) with ½” NPT F connections.
(with air supply at 590 kPa
– 85 psi)
Accuracy With linear cam ± 1%
Accessories
Electro-pneumatic version
– Pressure gauges – Change-over plate with
by-pass valve
– Stainless steel spool valve – Special construction for
corrosive environment (electronic or pneumatic)
– Integrated air-lock
Amplification
A signal or stroke deviation smaller than 2% generates the maximum
output pressure.
Weights
