Limiter
Combination
Two pressure limiters with integrated pressure transmitter.
Via the analog signal of the pressure transmitter, the PLC
receives the current pressure in the gas inlet. Warning and
switch-off points for exceeding or falling below certain
pressures are stored in the PLC. When the shutdown
points are reached, the system will be switched off via the
PLC.
A message is displayed when the warning points are
reached.
