1 Application
The pressure switch monitors extremely low pres-
sure differentials and triggers switch-on, switch-off
or switch-over operations if a set switching point is
reached.
The switching point can be adjusted using a hand
wheel.
The pressure switch monitors positive and negative gas
pressures on various industrial gas and air appliances,
such as boiler fan monitoring and differential pressure
monitoring in firing, ventilation and air-conditioning
systems.
C60 97 · Edition 01.193
Pressure switch C6097A switches in the event of decreasing pressure, C6097B switches in the event of
increasing pressure.
Pressure switches with manual reset lock off after
switching.
Pressure switches with an 0.2 mm (0.008") nozzle are
supplied with an integrated vent limiter, see page 8
(Vent limiter).

The air flow generated by the fan may be monitored as
follows:
The static pressure is monitored by the pressure switch
(PZL) as long as it can be demonstrated that the display consequently shows an adequate and secured flow
of air, or the pressure switch (PDS) checks the flow of air
via the differential pressure on the orifice.
If there is no air pressure supplied or if there is no differential pressure on the orifice, the system will be blocked.

Min./Max.
If the pressure is either too low or too high,
the min./max. pressure switch (PZL/PZH) switches in
order to avoid start-up or to initiate a safety shut-down.
Pressure switch C6097A switches with falling pressure,
C6097B switches with rising pressure.
Once the set switching point is reached, a micro switch
is activated in the pressure switch which is designed as
a change-over contact.
The switching pressure is adjusted using a hand wheel.

Measurement point
3.1 Vent limiter
The flow on FM approved and UL listed pressure
switches is limited by the nozzle. In the event of a
diaphragm tear, the escape of gas is limited to less
than 1.0 CFH of natural gas, see max. inlet pressure,
page 23 (UL, FM certified pressure switches), Adjusting range, switching hysteresis.

3.2 Positive pressure measurement
Positive pressure measurement is designed, for ex-
ample, for checking the fan function or measuring the
min./max. gas pressure.

Gas, air, flue gas, biogas
The positive pressure is measured in the lower dia-
phragm chamber, port 1 (or 2). The upper diaphragm
chamber is ventilated via port 4 (or 3).
3.3 Negative pressure measurement
Negative pressure measurement is designed, for exam-
ple, for monitoring a suction pressure blower.

Differential pressure measurement is designed for
safeguarding an air flow rate or for monitoring filters
and fans, for example.
