Low Range – Hermetically Sealed Differential Pressure Switch
Designed primarily for low pressure clean air and gas applications, the hermetically sealed low range differential pressure switch accurately reads very low pressures in hazardous areas requiring protection. The 107EL uses a diaphragm with a large sensing area and is the ideal choice for pressurized room (clean room) applications because it measures the difference between one room and another (air ducts) and lets you know if a air filter is clogged. External set point adjustment with visual indication is standard, allowing simplified switch calibration.
- Hermetically sealed pressure switches
- Varies from 0 to 40 in wcd
- Setpoint adjustment without declassifying the hazardous area
- SPDT or DPDT switching element

Pressostat V1
Le pressostat étanche SOR V1 à dead band réglable est une alternative économique à son homologue antidéflagrant. Il est idéal pour une utilisation dans des environnements non dangereux où une large dead band réglable entre les points de consigne est requise.
Ce pressostat intègre deux éléments de détection de pression statiques à joint torique, éprouvés dans l'industrie. La pression du fluide sur les surfaces des pistons contrebalance les forces des ressorts de piston réglables indépendamment, entraînant ainsi le déplacement des axes des pistons pour actionner l'ensemble du levier, qui, à son tour, active et désactive l'élément de commutation électrique.
- Réglable sur site
- Dead band réglable étroite ou large
- Utilisable en intérieur comme en extérieur
