1 Introduction

1.1 Overview

The SLN 700 SmartLine 80 GHz Non-Contact Radar transmitter is an electronic instrument designed to measure levels of liquid and solid materials. Non-Contact Radar (NCR) transmitters use Frequency Modulated Continuous Wave (FMCW) radar signals that are reflected by the material to be measured. The difference in frequency between the received and transmitted signal is directly proportional to the distance to the liquid and can be measured with high precision. Its small beam angle and small antenna size makes it easy to install. In comparison to other level measurement technologies, NCR provides a highly-accurate, cost-effective, reliable measurement in applications where Guided Wave Radar (GWR) are not suitable.

1.2 Transmitter Models

The SLN 700 SmartLine 80 GHz NCR transmitter is available as a part of the family of SLN700L models for liquid and SLN700S for solid applications. The pressure and temperature range is -40 to 200°C/-1 to 40 bar for both, and each model is available with a range of flange or threaded antenna, lens diameters, process connection, and accessories to suit most applications.

1.3 Transmitter Components

Overview of components

As shown in Figure 1-1, the transmitter consists of:

•Electronics housing containing the core measurement module and optional display module

•Process connection

•RF antenna

Figure 1-1 Components of the Level transmitter

Electronics

The Electronics consists of 2 distinct modules; core measurement electronics module and an optional display module. Both are replaceable in the field.

To make changes to the transmitter setup or configuration without the use of an external device such as a handheld or PC, an optional 4-Button interface is available.

The Optional Display module has the following features. (needs to be updated)

•Echo stem plot for checking measurement accuracy

•Standard and custom engineering units

•Diagnostic alerts and diagnostic messaging

•English and Chinese language options

Process Connector

The 80 GHz non-contact radar transmitter has 3 different series of products and associated process connections.

1.4 Communicating with the Transmitter

Level monitoring is possible through either the analog current (4-20 mA) or HART. It is possible to configure a transmitter using HART© protocol or using the four-button interface and display. Refer to manual 34-SL-25-16, SLN700 NCR HART Option Manual for details on available HART commands

1.5 SLN 700 Transmitter Label

The transmitter label is mounted on the side of the electronics housing (see Figure 1-2) and lists the following properties:

•Model number

•Physical configuration

•Power supply voltage

•Maximum working pressure rating

•Certification, if ordered (SIL and CRN)

1.6 Transmitter Model Number Description

The model number is comprised from a number of selections and options that can be specified when ordering the transmitter. It includes a basic transmitter type such as SLN720 (standard temperature, standard pressure) followed by a maximum of nine additional character strings that can be selected from a corresponding Table in the Model Selection Guide (MSG).

The basic model number structure is shown in Figure 1-3.

Figure 1-3: Standard SLN 700 Model Number

For a more complete description of the various configuration items and options, refer to the SLN

700Product Specification (34-SL-03-06) and Model Selection Guide (34-SL-16-20).

1.7Safety Certification Information

SLN transmitter models are available for use in Intrinsic Safe locations, including IECEx, ATEX, and NEPSI approvals. See SLN 700 Product Specification (34-SL-03-06) or SLN 700 Quick Start Guide (34-SL-25-14) for details and other approvals.

2 Radar Level Measurement

2.1 Overview

This chapter describes the theory of operation of the transmitter and discusses how measurements are affected by tank and process conditions.

2.2 Theory of Operation

The fundamental principle of operation is level measurement through the reflection of frequency modulated radar waves (FMCW technique). The antenna emits a continuous wave of radiation near 80 GHz whose frequency linearly increases in time in a saw tooth pattern. When the return pulse is detected by the same antenna, the processing electronics use a Fourier Transform technique to calculate the difference between the frequency of the generated and reflected signal. This difference is proportional to the distance of reflection.

3 Mounting

Due to the finite beam angle and resulting transmission cone, there should be no obstacles in the area radiated by the transmitted microwave beam from the lower edge of the antenna to the material surface to be measured. Therefore, it is necessary to avoid these facilities in the tank during installation. These include ladders, limit switches, heating equipment, supports, etc. If necessary, some of the obstacles can be removed from the measurement using background subtraction ("Virtual Echo Learning"). In addition, please note that the microwave beam should not intersect with tank fluid in or out flows. Please also note that the highest material level should not enter the near range (see Figure 3-1), the instrument should be kept at a certain distance from the wall of tank wall and the transmitting antenna should be perpendicular to the measured material surface as much as possible. The instruments installed in a hazardous classified area shall follow the local national installation regulations.

The reference plane for measurement is the sealing surface of threads or flanges.

Moisture-proof

For instruments that are installed outside, in a wet environment, and cooling or heating tanks, the cable gland must be tightened. The cable, at the cable gland entry, must be bent downward to prevent moisture as shown in Figure 3-2.

Installation position

During the installation, please note that the instrument should be kept minimal distance to tank wall from the vessel wall. For different antenna, please refer to Table 3-1.

However, the instrument must not under any circumstances be mounted closer than 200mm to the vessel wall or values calculated from Table 3-1.
