Setpoint. Depending on the switch and the vendor, the switching
pressure setpoint may be fixed or adjustable
- Q series single pressure controls can be not only used in
fluorinated refrigerant, but also in the air and liquid(allowed
liquid temp. -20 to 120°C)
- Adjustable range and differential settings
- Renovated SPDT micro-switch ensures the reliable switch function
- Flexible mounting bracket suits various kids of application
- Upper lid is optional (IP44)
- Various connections are available on request
- Automatic and manual reset version
- The material of bellows is copper and pressure interface is brass
- Several models available in drip-proof enclosure for marine
applications or in explosion-proof enclosure for special
applications
- CE approval
