System for Cargo Tank

Accuracy ±2 mm Outputs  4 - 20 mA, Ethernet, RS485 I.S. approval EEx ia IIC T6 Protection IP68 Operating temperature:   Ambient -40°C - +85°C Liquid -40°C - +120°C Working pressure up to 40 bar Material AISI 316

Ultrasonic Liquid Level Switch ASL - 400

THE ULTRASONIC LIQUID LEVEL SWITCH ASL-400 is constructed for using on sea-going vessels and in industrial plants. This is the new pure static (patented) sensor work upon the principle of distributed acoustic waves in a metal rod. During its life (MTBF 25 years), ASL-400 needs no adjustment.

Sensitive piezo-ceramic components and electronics are placed at the top of the sensor, not in direct contact with liquids, but perceive the liquid presence through acoustic waves propagated inside a long metal rod. This helps to reach extreme working temperatures (-200°C - +200°C)

Features:

• Static metallic rod sensor
• No vibration principle, no optics
• No function-dependence of density, viscosity, conductivity and permitivity
• No sensitiveness against soil
• Manual or Automatical function test device
• Special execution for high aggressive media with Hastelloy C, all wetted parts or anti-corrosive varnish coating

Repeatability ±2 mm Output  4 - 20 mA current loop:   12 mA alarm   5 mA no alarm I.S. approval EEx ia IIC T6 Protection IP68 Operating temperature:   Ambient -40°C - +85°C Liquid -200°C - +250°C Working pressure up to 400 bar Material AISI 316
