Product catalog summary
Introduction
Pressure and vacuum switches are essential in industrial and automotive applications for converting pressure values into electrical signals to manage machine cycles or signal issues like leaks or alarms. These devices are tailored to specific applications.
Types of Pressure Switches
1. Normally Open (NO): Contacts close when set pressure is reached.
2. Normally Closed (NC): Contacts open when set pressure is reached.
3. Single-Pole Double-Throw (SPDT): Allows use of either NC or NO contacts.
Settings and Hysteresis
Pressure switches can have adjustable or fixed settings, with a maximum pressure variation rate of 1,000 bar/s. Hysteresis is the pressure difference between switching points, influenced by model and pressure ramp amplitude.
Maximum Working and Safety Pressure
Defines the highest pressure the sensor can withstand without damage and the maximum pressure ensuring structural integrity.
Fittings and Assembly
Proper fittings and vertical mounting are crucial to prevent particle accumulation.
Electrical Load and Impact
Relays are recommended for slow pressure fluctuations near contact current ratings. Avoid strong impacts or vibrations.
Caps and Connectors
Protection ratings range from IP54 to IP69K, valid only with properly plugged connectors.
Custom Design
Custom pressure switches are available for specific needs, such as stainless steel construction or de-oiled housing.

INTRODUZIONE INTRODUCTION Introduzione Nelle applicazioni industriali ed automotive si richiede frequentemente che il raggiungimento di un valore di pressione, precedentemente impostato, venga trasformato in un segnale elettrico, utilizzato per dare inizio al ciclo macchina oppure per segnalare una determinata situazione. (es. perdite nell’impianto, allarmi, etc.). Queste operazioni sono generalmente gestite da componenti, tarati in funzione dell’applicazione, che prendono il nome di PRESSOSTATI e VUOTOSTATI. signals can be of three types: • with single-pole single-throw (SPST) electric contacts...

INTRODUZIONE INTRODUCTION Taratura L’Azienda offre pressostati con taratura regolabile e fissa. Nei modelli a taratura regolabile, per la regolazione alla pressione desiderata, agire sul grano di regolazione facendo attenzione a non mandare a pacco la molla. La pressione aumenta ruotando in senso orario. Dopo aver effettuato la taratura è opportuno bloccare la vite con un collante. I pressostati a taratura regolabile possono essere tarati in fabbrica al valore di pressione richiesto dal cliente, tale valore indica il punto di intervento per pressione crescente. A richiesta la taratura può essere...

INTRODUZIONE INTRODUCTION Carico elettrico pilotato Le caratteristiche elettriche dei contatti sono riportate nei dati relativi ad ogni serie di pressostati. Il nostro Ufficio Tecnico è a disposizione del Cliente per qualsiasi chiarimento. In caso di variazione lenta di pressione nei pressostati con contatti SPST è consigliabile non pilotare carichi elettrici le cui caratteristiche siano vicine ai limiti di corrente del contatto stesso. In tal caso si suggerisce di interporre un relè tra il pressostato ed il carico. Per i prodotti con max tensione commutabile sino a 48 V l’alimentazione deve...
