SM85

Product catalog summary
Overview: The SM85 is a cost-effective device designed for monitoring minimum and maximum levels in silos or hoppers containing non-sticky materials, powders, or granular substances such as rice, grains, plastics, coffee, sand, and lime. It operates by using the pressure exerted by the material on a membrane to activate a quick-action microswitch. The sensitivity of the switch can be adjusted using a screw on the device's cover. The device is unaffected by humidity and temperature changes, and the membrane is resistant to shocks and vibrations. It is mounted externally on the silo wall using three holes on the fixing flange.
Specifications: The SM85 features a shockproof and self-extinguishing plastic case with an aluminum fixing flange. The membrane is made of non-toxic black rubber with a diameter of 82 mm, while the ATEX version uses antistatic silicone rubber. The response sensitivity is a minimum of 50 grams centrally, with 20 mm of water pressure on the membrane. The device has an IP65 protection degree and can handle electric contacts up to 6A at 250V, with the ATEX version rated at 30V - 100mA. It operates within a temperature range of -10°C to +80°C under atmospheric pressure.
ATEX Version: The SM85.ATEX is designed for environments where a potentially explosive atmosphere, such as a dust cloud, may be present inside (process zone 20) or outside (environment zone 21) the tanks. Installation of the SM85.ATEX must be paired with an intrinsic safety barrier to ensure proper separation between safe and hazardous zones.
Standards and Compliance: The device complies with electromagnetic compatibility standards 2004/108/EC and low tension standards 2006/95/EC. It is also certified under 94/9/EC for explosive atmospheres with specifications II 1/2 Ex iaD A20/21T85°C -10°

CONTROLLI DI LIVELLO A MEMBRANA PER MATERIALI IN POLVERE O GRANULARI MEMBRANE LEVEL CONTROL FOR POWDERS OR GRANULAR MATERIALS STANDKONTROLLE MIT MEMBRAN-SENSOR SM85 é un semplice ed economico apparecchio adatto al controllo del livello minimo e massimo in silos o tramogge contenenti materiali, non collosi, in polvere o granulari, quali riso, cereali, materie plastiche, caffè, sabbia, calce, ecc. Il funzionamento è molto semplice: la pressione esercitata dal prodotto sulla membrana fa azionare un microinterruttore a scatto rapido. La sensibilità dello scatto è regolabile mediante una vite posta sul coperchio dellʼapparecchio. Variazioni di umidità e temperatura non hanno influenza sul funzionamento, la membrana è resistente ad urti e vibrazioni. Il montaggio è esterno sulla parete del silo mediante i 3 fori posti sulla flangia di fissaggio. SM85 per il controllo del livello di materiali in polvere o grani in assenza di polvere combustile. SM85.ATEX per il controllo del livello di materiali in polvere o grani in serbatoi allʼinterno dei quali (zona di processo 20) o allʼesterno dei quali (zona ambiente 21) unʼatmosfera potenzialmente esplosiva sotto forma di nube o polvere può essere presente. Lʼinstallazione del SM85.ATEX deve avvenire obbligatoriamente in abbinamento ad una barriera a sicurezza intrinseca in grado di fornire lʼadeguata separazione tra zona sicura e zona pericolosa. The SM85 is a simple and economical instrument suitable for the minimum and maximum level control inside silos or hoppers that contain no sticky materials, powders or granulars like rice, corns, plastics, coffee, sand, lime, etc. Working is very simple: the pressure practiced by material on membrane activates a trigger. Trigger sensibility is adjustable by a screw placed on the instrument tap. Humidity and temperature variations do not affect working, the membrane is collision and vibration proof.The mounting is external on the siloʼs wall by the means of 3 holes placed on the fixing flange. SM85 for the control of the level of powders or granulars in absence of fuel dust. SM85.ATEX for the level control of materials, where, inside (process zone 20) or outside the tanks (Environment zone 21) a potentially explosive atmosphere, like dust cloud, can be present. The installation of SM85.ATEX has to be compulsory coupled to an inherent safety barrier in order to carry out a suitable separation between the safety zone and dangerous zone. Die SM85 Füllstandskontrolle ist ein einfaches und ökonomisches Kontrollsystem zur Überwachung des Minimum- und Maximumfüllstandes in Silos oder Trichtern. Dieses System eignet sich für besonders trockenes Medium, pulver – oder granulatförmig, zum Beispiel Reis, Getreide, Kunststoffe, Kaffee, Sand, Kalk, usw. Die Funktion ist sehr einfach: der vom Produkt ausgeübte Druck auf die Membrane betätigt einen Mikroschalter mit Auslöseschalter. Die Sensibilität des Kontaktes, lässt sich über eine Justageschraube an der Geräterückseite einfach einstellen. Temperatur- und Feuchtigkeitsveränderungen haben keinen Einfluß auf die Funktion, die Membrane ist stoßfest und unempfindlich gegen Schwingungen.Die Montage erfolgt an der Außenseite der Behälterwand über einen Anschlussflansch mit 3 Befestigungsbohrungen. SM85 insgesamt für der Füllstandskontrolle von staubigen oder körnigen Material in Fehlen von Brennstaub. SM85.ATEX für der Füllstandskontrolle von staubigen oder körnigen Material innerhalb des Tanks (Arbeitzone 20), oder auch in der Aussenumgebung (Umgebungzone 21), wo sich möglicherweise eine explosive Atmosphäre entwickeln kann die wie eine Volke oder Staub aussieht. Die Einrichtung von SM85.ATEX muss zwangsmäßig zu einer innere Sicherheitsschranke verbindet sein, die eine angemessene Abtrennung zwischen Sicherheitszone und gefährlicher Zone verseht. 14
