Actuator; HART device type 7
Yes, available through HART Communication Foundation
ValVue 2 AMS SNAP-ON application available
Dry, oil-free, 5 micron filtered air (See ISA S7.3)
Direct
20 - 80 psi (1.4 - 5.52 bar) max.
Regulate 5 to 10 psi above actuator spring range.
Do not exceed actuator rating.
10.0 scfm (280 l/m) at 30 psi (2.1 bar) supply
16.6 scfm (470 l/m) at 60 psi (4.2 bar) supply
23.3 scfm (660 l/m) at 90 psi (6.3 bar) supply
0.2 scfm (5.7 sl/m) at 30 psi (2.1 bar) supply
0.26 scfm (7.4 sl/m) at 45 psi (3.1bar) supply
On supply failure the actuator output drops.
Some overshoot may occur when air pressure
returns after a period without air supply pressure.
Always set control set point to 0%, and put the
process control system in manual, for smooth
recovery from air supply failure.
Output drops to low pressure.
80 psi (5.52 bar) max
