Pressostats
Pressure switches are controls used to monitor pressure and switch electrical contacts when a set pressure is reached, supporting monitoring, alarm, regulation, and protection functions. This product group covers both electronic and electromechanical pressure-switch solutions for refrigeration, air conditioning, industrial, marine, steam, boiler, compressor, and water-booster applications.
Features and benefits
- Greater accuracy, excellent long-term stability, simpler operation, and a high number of switching cycles are highlighted for electronic pressure switches.
- Advanced electronic pressure switches are positioned to improve safety, extend equipment lifecycles, and reduce maintenance costs.
- Excellent shock and vibration robustness is highlighted in key product families.
- Wide pressure ranges and a broad choice of pressure and electrical connections are available in the wider Danfoss pressure-switch portfolio.
- High reliability and long service life are emphasized for core refrigeration-oriented families such as KP.
- Snap-action contact systems are highlighted in the broader industrial pressure-switch program and in KP-based refrigeration solutions.
- Fully welded or stainless-steel-based designs are highlighted in selected product families.
- The category covers both standard refrigeration applications and more demanding industrial or marine environments.
Product types shown: 7
BCP
The BCP type is a series of dedicated pressure switches for safety and pressure monitoring of steam and hot water boilers. The BCP incorporates a single-pole changeover microswitch where the contact position depends on the pressure in the connection port and the range set value. For installations, in which operation is particularly critical for safety reason, the use of fail-safe control is recommended.
CAS
The CAS series consists of a series of pressure controlled switches and temperature controlled switches. In this series, special attention has been given to meeting demands for a high level of enclosure, robust and compact construction and resistance to shock and vibration.
The series is suitable for use in alarm and regulation systems in factories, diesel plants, compressors, power stations and on board ships.
CS
Les pressostats de la gamme CS disposent d'un contact manométrique tripolaire intégré. La position du contact dépend de la pression dans le connecteur, du réglage de la plage et du différentiel réglable. Les pressostats disposent d’un interrupteur manuel pour bloquer le système de contact en position ouverte indépendamment de la pression dans le système. Les pressostats équipés de soupape de décharge servent dans les systèmes d'air comprimé où une décharge de la pression sur le piston du compresseur est nécessaire avant le démarrage. Le pressostat CS est conçu pour le démarrage et l'arrêt automatique de compresseurs à air et de pompes à eau pressurisée.
KP / KPI
Les pressostats et thermostats KP et KPI sont utilisés dans les systèmes de contrôle, de surveillance et d'alarme d'une grande variété d'applications industrielles.
Les pressostats KP sont principalement utilisés pour les fluides gazeux, tandis que les pressostats KPI conviennent davantage aux fluides liquides et gazeux. Ces produits sont disponibles en boîtier IP30 et IP55.
La gamme de pressostats KP comprend des pressostats et des limiteurs spécialement conçus pour les chaudières à vapeur et autres applications de chauffage.
Pour la commande et la protection de la pompe à eau (marche à sec), le pressostat double KP44 est adapté et assure une durée de vie prolongée de la pompe.
KPS
The KPS series consists of a series of pressure and temperature controlled switches. In this series, special attention has been given to meeting demands for a high level of enclosure, robust and compact construction, and resistance to shock and vibration.
For KPS pressure switches the position of the contacts depends on the pressure in the inlet connection and the set scale value.
The series covers most outdoor as well as indoor application requirements and is suitable for use in monitoring alarm and control systems in factories, diesel plants, compressors, power stations and on board ships.
MBC 5000 / MBC 5100
Les pressostats MBC sont utilisés dans les applications industrielles et marines où l'espace et la fiabilité sont les caractéristiques les plus importantes.
Les MBC sont des pressostats compacts, conçus selon notre conception modulaire pour résister aux conditions difficiles des salles des machines à bord des navires.
Les contrôleurs de pression de masse (MBC) présentent une haute résistance aux vibrations et le MBC 5100 bénéficie de toutes les homologations marines courantes. Le différentiel fixe, mais faible, garantit une surveillance précise des pressions critiques.
Les vannes de test MBV peuvent être livrées en option standard pour MBC.
RT
RT pressure switches incorporate a pressure controlled, single-pole change over switch where the contact position depends on the pressure in the connection port and the set value. The RT series consists of pressure switches, differential pressure switches and pressure switches for neutral zone regulation, all for general use within the industrial and marine segments. The series also covers safety pressure switches dedicated for steam boiler plants. For installations in which operation is particularly critical from safety and economic points of view, the use of fail-safe pressure switches is recommended. The use of gold-plated contacts is also recommended in such installations, provided operation involves only a few switching cycles or signal currents and voltages.
