Application
C6097 with CE approval.
Hand wheel with mbar scale.
M16 cable gland for electrical connection.
1 Application
The pressure switch monitors extremely low pressure 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.
C6097 with UL listing and FM approval. Hand wheel with "WC and mbar scale. 1/2" NPT conduit for electrical connection.
C6097 can be supplied with lock-off function.
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.

Function
3 Function
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.

Pressure switches which lock off after switching can only be unlocked with a manual reset, see page 16 (Resetting pressure switches with manual reset).
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.

Function
3..2 Positive pressure measurement
Positive pressure measurement is designed, for example, for checking the fan function or measuring the min./max. gas pressure.
3..4 Differential pressure measurement
Differential pressure measurement is designed for safeguarding an air flow rate or for monitoring filters and fans, for example.
