OPTISWITCH 4000 | 5000 series Vibration level switch for basic applications* Point level detection of liquids * Virtually unaffected by the chemical and physical media properties * Density: ≥0.5 g/cm3 / 0.018 lb/in3 * -40…+150°C / +302°F; -1…64 barg / -14.5…925 psig The OPTISWITCH 4000 is a vibration level switch for simple liquid applications. It is a universal and cost-effective device for level detection in small vessels. It detects low or high level and is mostly used for overfill, dry-run or pump protection. Installations in pipelines are also possible. Product highlights * Simple and robust tuning fork * Virtually unaffected by the chemical and physical properties of liquids * Outputs: contactless electronic switch or transistor * Optional version for hygienic applications Typical applications * Pump and dry-run protection * Limit and overfill detection * Liquid detection in pipes Product details Alternative product categories : Tuning fork, Vibration fork, Vibronic Technical data Measurement principles : Vibrating Level measurement type : Point level detection Measured media : Liquids Contact to measured medium : Yes Interface measurement : No Probe length : 66 mm / 2.6 in Process pressure (relative) : -1…64 barg/ -14.5…925 psig Process temperature : -40…150°C/ -40…302°F Wetted parts : Austenitic stainless steel (1.4404/316L) Process seals : EPDM, FKM/FPM, Kalrez® 6375, PFA Process connections Thread connections : Male: G1/2, G3/4, G1 1/2 NPT, 3/4 NPT, 1 NPT Hygienic connections : Dairy screw (DIN 11851): DN25, DN40, DN50 Varivent®: N SMS (1145): 38 mm Clamp (DIN 32676): DN25, DN40, DN50 Communication Binary outputs : Contactless, Transistor
