U-GAGE M25U Ultrasonic Sensors

Overview

Waterproof, stainless steel, ultrasonic sensors were purpose-built to deliver flawless operation in food processing and other sanitary industries.

  • Dual range/dual speed opposed mode ultrasonic sensors; ideal for sensing clear objects or materials
  • Features smooth 316 series stainless steel construction to withstand the toughest sanitary environments
  • Rated IP69K, IEC IP67 (NEMA 6) with fully encapsulated electronics
  • Wide standard operating temperature range of -20° to +70°C (-4° to +158° F)
  • Withstands high-temperature sprays of up 80°C and 1500 psi occurring every few hours
  • Constructed of FDA approved materials; cleans easily with no threads, gaps or seams to trap debris
  • Highly immune to ambient sonic and electrical noise

Notes1. NPN < 200 μA for load impedance > 3 KΩ; for load current of 100 mA, leakage < 1% of load current



2. When mounting the M25U, care should be taken to acoustically isolate the emitter and receiver to eliminate sound energy coupling between the sensor pair. This is best accomplished with elastomeric materials between the sensor and rigid mounting brackets.
