• Built to suit your specific needs.
• Number of points and location determined by customer.
• Switch points are independent of each other.
• Local or remote electronics.
• Removable, plug in electronics.
• All welded materials of construction 316L Stainless Steel (std).
• Free of all moving parts that can stick, coat or fail.
• Fast response time of .1 to 1 second on wetting, media dependent.
• Switch on level change of .03 inch without concern for changing temperature, density, dielectric constant or chemical composition.
• Self heating sensor design improves repeatability and reliability. No separate heater to fail or slow response time.
• Wide operating temperature range -100°F to +572°F (-70°C to+300°C).
• Temperature compensation circuitry eliminates false switching due to process temperature changes.
• Both the VERSA-SWITCH® and microtuf® families of multi-point level switches can provide a solution for your demanding point level applications.
