阿美特克AMETEK超聲波液位變送器的詳細資料

阿美特克AMETEK超聲波液位變送器

This new series of ultrasonic measurement instruments includes two-wire loop-powered and mains-powered variants. It adopts non-contact measurement technology and is suitable for continuous measurement of liquids and slurries. It can realize level monitoring, distance measurement, volume calculation and open channel flow measurement.

The transmitter is equipped with patented SMART GAIN™ circuitry. It can automatically filter false echoes generated by tank internal obstacles and agitator blades without manual adjustment.

It provides excellent measurement accuracy: up to 0.15% of the measuring range within the maximum 30 ft measuring distance.

The two-wire HART version has intrinsically safe and explosion-proof structures, which can be used in Class 1, Division 1 hazardous areas.

Electrical Specifications

Input Power: 19 to 30 VDC; Minimum 19 VDC at 4mA operating current.

Output signal: Two-wire 4-20mA with isolated HART communication.

Maximum Loop Resistance: 600 ohms at 24VDC.

Output Mode: Level, Distance, Flow, Volume.

Display

2-line, 7-digit LCD display.

Top line character height: 0.25 inch; Bottom line character height: 0.36 inch.

The display is UV resistant and no sunshield is required for outdoor installation.
