Specification of

PNEUMATIC CONTROLLER FISHER TYPE C1

Input Signal
Pressure
Type: Gauge pressure, vacuum, compound
pressure, or differential pressure of a liquid or gas
Limits: See table 2 or 3
Output Signal
Proportional or Proportional-Plus-Reset Controllers
and Transmitters: 0.2 to 1.0 bar ( 3 to 15 psig) or
0.4 to 2.0 bar ( 6 to 30 psig) pneumatic pressure
signal
Differential Gap Controllers: 0 and 1.4 bar
( 0 and 20 psig) or 0 and 2.4 bar ( 0 and 35 psig)
pneumatic pressure signal
Action: Control action is field reversible between
direct ( increasing sensed pressure produces
increasing output signal) and reverse ( increasing
sensed pressure produces decreasing output signal) .
