2 About us j a c o b - t h e s p e c i a l i s t f o r c a b l e g l a n d s a n d m e a s u r i n g t e c h n o l o g y The success story begins in 9. Wilhelm Jacob founds a small family business in Stuttgart, which turns into a successful industrial company in the south of Germany. Since those days, the main focus has always been on the production of high quality products for industrial customers and electro wholesalers. Over the years Jacob developed from the original small business to a branch leader. Our products are being used worldwide in the electro technical industry, for panel building, machine building or at your nearby electro wholesaler. Jacob is not only one of the leading manufacturers of cable glands but also a specialist in measuring technology and individual solutions for specific applications. Flexibility and velocity is important for the satisfaction of our customers. We take care that our orders are being delivered quickly and punctually. Our new logistic and production centre in Kernen built in the year 009 enables us to give the best delivery service to our customers. This is important to us. Investment in modern production technology is a must at Jacob for the development of our company and for continuous innovation. Our products are part of complex machinery and plant equipment and though small nevertheless important for the function of the equipment. Therefore our goal is 00% customer satisfaction. Jacob is your competent partner offering extensive customer service and support with a background of more than 85 years experience in product development and production. Together with our partners and customers we develop high quality solutions for their applications. Jacob GmbH Elektrotechnische Fabrik Gottlieb-Daimler-Strasse 794 Kernen Fon Fax jacob@jacob-gmbh.de

3 Optical s Jacob Typ LO the applications The optical sensors are suitable to use in high pressure applications for level detection of liquids in Tanks, containers, vessels, Heating- climate- and cooling Installations, Refrigeration compressors and Engines. important characteristics Available in plastics and stainless steel Setting of sensitivity by factory adjustment Application with high pressure ranges max bar (plastic), max bar (stainless steel) The body material is glass-fiber reinforced polysulfone (PSU) or stainless steel with sensor dome of glass Transistor exit for the direct connection to a SPC Time delay can be adjusted over a SPC or optionally over the intgrated timer ex factory LED displays for operating and switching status (Type LO 4 + LO 44) Simple operational principle for a large application scope No moving parts Small installation dimensions, installation position arbitrary The PSU type is FDA conformal, applicable in the food industry Available with an 4-0 ma temperature output signal field of applications Mechanical Engineering Chemical industry Pharmaceutical industry Energy industry Food and beverage industry Water economy the measuring principle The optical sensors work with infrared ray emitter and an optical receiver. In air (liquid not present), all the light is reflected - internally - by the dome and then redirected to the receiver. When the liquid reaches the sensor dome, a big amount of the light emitted is lost in the liquid and the sensor senses its presence. The switching function is alternatively selectable as NC or NO contacts with liquid contact. The delay time for the switching signal can be adjusted over a SPC, or optionally by an integrated timer, ex works preset. Receiver Emitter By the dome reflected LED-Light Receiver Emitter LED-Light is adsorbed by the fluid Jacob GmbH Elektrotechnische Fabrik Gottlieb-Daimler-Straße 794 Kernen Fon Fax jacob@jacob-gmbh.de

7 PSU-Resistivity vs Chemicals The polysulphone is a tough rigid, amorphous thermoplastic material. It is hydrolytically stable and has demonstrated long-term resistance to steam. Electrical properties are maintained over a wide temperature (-40ºC + 60ºC) and after immersion in water. The polysulphone is highly resistant to mineral acids, alkali, salt solutions, detergents, hydrocarbon oils. The polysulphone has FDA, USP, -A and NSF approvals, which allow food contact use and medical equipment use. Chemical Resistance + = resistent; 0 = partially resistent; - = not resistent; II = soluble Substance (concentration) Resistance Substance (concentration) Resistance Acetic Acid (80-0%) + Hydrogen Peroxide (0.5%) + Acetone (00%) - Hydrogen Peroxide (%) + Alcoholic Calcium Chloride (0%) 0 Hydrogen Peroxide (%) + Alkaline Solution 0.% CL Active - Hydrogen Peroxide (0%) + Aluminium Chloride (0%) + Hydrogen Peroxide (0%) + Aluminium Sulphur (0%) + Iodine and Potassium Solution - Ammonia (0%) + Iodine Tincture (-) - Ammonium Chloride (0%) + Lactic Acid (0%) + Benzene (00%) - Liquid Freon (00%) + Boric Acid (0%) + Magnesium Chloride (0%) + Butanol (00%) 0 Manganese Sulphur (0%) + Butyl acetat (00%) - Mercury (00%) + Calzium Hypochlorite (0%) + Mercury (5%) + Calzium Sulphur (00%) - Methanol (98%) 0 Carbon Tetrachloride (00%) - Methyl Chloride (00%) 0 Caustic Potash (0%) + Mineral Oil (00%) + Caustic Potash (50%) + Nitric Acid (0%) + Caustic Soda (0%) + Nitric Acid Conc.

The chemical stability of plastics is dependently of the temperature, concentration, radiation effect, mechanical/dynamic stress and not least of the careful production of the work piece (shatter crack danger). Therefore warranty and requirements for compensation cannot be recognized. For specific applications it is essential to make for the operating conditions appropriate attempts.
