Ультразвуковой передатчик уровня 3107, 4-20 мА

Overview of the Rosemount 3107 and 3108

Measurement principle

The 3107 and the 3108 are based on ultrasonic technology. Ultrasonic pulse signals are transmitted and reflected from the liquid surface. The transmitter ‘listens’ for reflected signals (echoes) and measures the time-delay between transmitting and receiving.

The distance to the liquid surface is automatically calculated using the computed time-delay.

The 3107 has an integrated sensor for automatically compensating the Distance for temperature effects.

The 3108 has a factory fitted remote temperature sensor to continuously measure the air temperature around the transmitter. It then computesthe speed of sound in air, automatically compensating Distance for temperature effects.

The level measurement (Bottom Reference minus Distance) is sent through the 4–20 mA and HART output.

Choosing the right model

Each model of the 3100 Series has been designed for a specific purpose, as shown in the table below

Rosemount 3107 Level Transmitter Ordering

Specification and selection of product materials, options, or components must be made by the purchaser of the equipment.

Table 1. Rosemount 3107 ordering information

    The Standard offering represents the most common models and options. These options should be selected for best delivery.
    The Expanded offering is manufactured after receipt of order and is subject to additional delivery lead time.

(1) Choosing this option implies US (Imperial) units of measurement are required for the default configuration. Configuration can be changed on-site.

(2) Choosing this option implies Metric units of measurement are required for the default configuration. Configuration can be changed on-site.

(3) Contact an Emerson Process Management representative for additional information.

(4) When no Special Alarm option code is selected, the configuration is a high alarm, and standard Rosemount alarm and saturation levels.
