I. Introduction

A. General Description

The MS3500E/MS3510E is a battery powered, corrosion meter capable of measuring and storing data

from all types of electrical resistance (ER) corrosion probes. The instrument is light weight,

microprocessor-based, and features a simple, menu-driven interface using a keypad and a graphical LCD

display.

Corrosion rate measurements are made using the electrical resistance method. Essentially, the instrument

measures the resistance of the probe element which changes over time, as metal loss occurs. The rate of

change is directly proportional to corrosion rate. This method finds a wide variety of applications since it

can be used in conductive and nonconductive environments such as petroleum, chemical, water, soil, or

even atmosphere. The new high-resolution measurement of the MS3500E/MS3510E detects smaller

increments of metal loss, providing faster response than traditional ER instruments.

After taking a reading, the instrument displays metal loss in mils. All stored readings are automatically

time and date stamped. Readings are stored to non-volatile Flash memory which retains data without the

need for a battery backup.

The MS3500E/MS3510E High Resolution ER Data Logger can store more than 100000 readings. Stored

data can be downloaded directly to a USB Flash (“jump”) drive or Bluetooth compatible devices via

Bluetooth. Data can be opened and charted using the provided CDMS software, or it can be imported into

any standard data analysis (spreadsheet) program such as Microsoft Excel. Data can also be reviewed and

charted on the instrument’s LCD display for quick reference.

B. Principles of Operation

The MS3500E/MS3510E High Resolution ER Data Logger operates on the Electrical Resistance (ER)

technique and is used in conjunction with an ER probe. The ER probe utilizes a resistive sensing

element manufactured from the material of interest (or a close approximation) which is exposed to a

corroding environment. This is called the Exposed or Corroding Element. The resistance of the

Exposed Element is directly related to its thickness, so as the element corrodes the resulting loss of

metal causes a proportional

increase in

the element’s resistance. The probe also contains an internal

Reference Element which is used to compensate for the influences of temperature on the Exposed

Element.

The MS3500E/MS3510E High Resolution ER Data Logger is designed to work with any standard ER

probe, but it is recommended that Cylindrical and Large Flush type probes be used to ensure optimum

performance. Their physical design places the Reference Element in closer proximity to the Exposed

Element compared to other probe types, providing more effective temperature compensation and

thus reducing the effects of thermal noise.

Because they are designed to corrode, ER probes are sacrificial in nature. Each ER probe will have a

finite life that is based on the element thickness. ER probes are available in several geometries and

thicknesses designed to suit a wide variety of applications. Table 1 lists the common ER element

options available from Metal Samples and the effective life of each.

Table 1. Standard ER Probe Elements

The MS3500E/MS3510E High Resolution ER Data Logger measures an ER probe utilizing a high-

resolution, 16-bit measurement. This allows the unit to detect much smaller amounts of metal loss,

thus responding faster to corrosion events and upsets. At 16-bit resolution the MS3500E/MS3510E

ER Data Logger can measure metal loss amounts as small as 0.004% of the probe life. For highly

sensitive probes such as the 5-mil large flush shown above, that results in a detection limit of less

than one angstrom.

II. Start-up and Operation

A. Receiving the MS3500E/MS3510E High Resolution ER Data Logger

Check the MS3500E/MS3510E High Resolution Data Logger for any shipping damage when it is first

received. When the unit is unpacked, verify that the following items are included:

•Data Logger

•Battery pack (Shipped Separately)

•Meter Prover

•User’s Manual

•Current Loop Cable (MS3510E Model Only)

In the event of shipping damage, quantity shortage, or missing items, it is recommended that the

event is documented immediately and that digital photographs are taken. Any shortages or

missing items should be reported to Metal Samples immediately. In the event of shipping

damage, a claim should be opened with the responsible carrier.

B. Start-Up

CAUTION: Using this product in any way other than that specified within this manual may impair the

intrinsic safety protection.

Start-up of the MS3500E/MS3510E Data Logger involves the following steps:

1. Port Details and Probe Connection

2. Current Loop Connection (MS3510E Model Only)

3. Power-Up

4. Setup and Operation

1. Probe Connection

CAUTION: Using this product in any way other than that specified within this manual may impair the

intrinsic safety protection.

When selecting a location to mount the data logger it is important to consider the surrounding

environment. To ensure proper operation:

•Do not mount the transmitter in a location that exceeds its operating temperature.

•Avoid mounting the transmitter near sources of strong electrical noise.

•Ensure that there is sufficient clearance for installation and to open the transmitter cover

afterwards.

a. Remote Mounting

The unit is designed to mount remotely. The data logger is connected to the ER probe via the probe

extension cable. When possible, the data logger should be mounted within 10’ (3m) of the probe to

keep the probe cabling short and minimize signal degradation.

2. Current Loop Connection (for the MS3510E model)

To setup current loop communication, refer to the Control Drawing (Hazardous Area Wiring

Diagram), found in Appendix C: Control Drawing on page 36.

a. In the Safe Area only, connect the external current loop cable (shipped with the

instrument) to either:

-Certified Safety Barrier (EEx ia) IIC Typical of MTL 7787+

-Certified 4-20mA Repeater Power Supply (EEx ia) IIC Typical of MTL 5541+.

b. Connect the 2-pin connector from the external current loop cable to the instrument’s

4-20mA current loop port.

c. Current measurements will be explained in the “Comm./Loop” section on Page 19.

3. Power-Up

The unit is supplied with a battery pack in a separate package. Install the battery pack before starting

the product. The instrument can be powered up by pressing the ‘ON’ button on the keypad. The start-

up screen with the Metal Samples logo will appear on the screen; the start-up screen confirms the

software version currently running and the SD card status. The keypad switch layout is shown below.

a. Safe Area Usage

The MS3500E/MS3510E High Resolution Data Logger is approved for use in hazardous areas

but can be used in non-hazardous areas as well.

The cells in the battery pack must be replaced only in a safe area and it should be replaced

with batteries of the same make and model.

b. Hazardous Area Usage
