precision regulators

[admin]

Looking for a single analog voltage (0-5 VDC preferred) controlled regulator that will allow a span of 0.03 bar to 2 bar control. This is for a couple of leak test applcations, so high precision, linearity, and repeatability are essential

There are several names in proportional pressure controllers. They can also be called I/P (input to pressure) converters. Basically, all of them are 3 way valves. Here are the big names:Bellofram: voice coil designProportionAir: 2 valves design

(I to P) I think is current to pneumatic.As in 4 to 20 ma. to 3 to 15 psi or other ranges.Newton
