Magnetic switch For bypass level indicators Model …

1 Magnetic switchFor bypass level indicatorsModel BGUM agnetic switchFig. left: Reed switch , Model BGUFig. right: High-temperature reed switch , Model BGU-AHTA pplications Magnetic switches for detecting the limits of fi lling levels in bypass level indicators Chemical and petrochemical industries, oil and natural gas extraction (on- and off shore) Shipbuilding, machine building Power generating equipment, power plants Pharmaceutical, food, water treatment, environmental engineering industriesSpecial features Proper functioning, even under extreme environmental infl uences, dirt, humidity, gases, dust, chips Compact and operationally safe design Mounting of the switches with tightening strap or via T-slot at the Magnetic display Medium temperatures from -196 .. +380 C Versions with reed contact, proximity switch , micro switch or rotation magnetDescriptionThe Model BGU Magnetic switches serve to detect the limits of fi lling levels in bypass level indicators .

2 They generate a binary signal which can be fed to down-stream signalling or control equipment. Bistable versions enable the storage of Magnetic switches are mounted directly to the bypass level indicator with a tightening strap or to the Magnetic display with sliding Magnetic switches are available with diff erent approvals and with SIL measurementFor selecting the optimum switch ( switch Model , approval, switching option, cable length, cable material) we off er application-related technical data sheet BGUPage 1 of 10 KSR data sheet LM 02/2015 Model overviewSwitch modelDescriptionApprovalSwitching powerTemperature rangewith-outEx i Ex d GL Ex i + GLAC 230 V, 60 VA, 1 AAC 250 V, 100 VA, 2 AAC 250 V, 5 A (micro switch )Proximity switchBGUReed, aluminium case, cable outletx x x x x x-50.
