ULS 200S

Product Description

ULS 200S Contact Type Ultrasonic Level Switch is designed to reliably detect the presence or absence of liquid in direct contact with the sensor. It operates using an ultrasonic contact sensing principle, converting sensor current into a potential-free relay output for alarm or control applications. The switch offers high switching accuracy of ±2 mm with fast actuation time of less than 0.5 seconds. Constructed with an SS-316L probe and housed in an IP-65 stainless steel enclosure, it is suitable for a wide range of liquids and oils. Clear LED indications provide status for power, system health, and alarm conditions. With multiple process connection options and robust industrial design, the ULS 200S ensures dependable performance in demanding environments.
