Input Signal (Process Sensor Range)
Lower and Upper Range Limits:
Maximum Allowable Operating Limits:
Output Signal
Proportional‐Only, Proportional‐Plus‐Reset, or
Proportional‐Plus‐Reset‐Plus‐Rate Range:
0.2 to 1.0
bar or 0.4 to 2.0 bar (3 to 15 psig or 6 to 30 psig)
Differential Gap Range:
0 and 1.4 bar (0 and 20 psig)
or 0 and 2.4 bar (0 and 35 psig)
Action:
Field‐reversible between direct (increasing
sensed process pressure increases output pressure)
or reverse (increasing sensed process pressure
decreases output pressure).
Process Scale
Standard scale is matched to the range of the sensing
element, with the exception of receiver controllers.
Optional
scales are available.
Process Connections
Standard:
1/4 NPT, internal, stainless steel
(all input ranges)
Optional:
Supply and Output Connections
1/4 NPT, internal
Supply Pressure Requirements
Supply Pressure Medium
Air or Natural Gas
Supply medium must be clean, dry, and noncorrosive
Per ISA Standard 7.0.01
A maximum 40 micrometer particle size in the air
system is acceptable. Further filtration down to 5
micrometer particle size is recommended. Lubricant
content is not to exceed 1 ppm weight (w/w) or
volume (v/v) basis. Condensation in the air supply
should be minimized.
Per ISO 8573-1
Maximum particle density size:
Class 7
Oil content:
Class 3
Pressure Dew Point:
Class 3 or at least 10
