Product Description

TBE-10 is an in-line optical sensor that mounts directly to the
process line, providing real-time information about the process.

TBE-10 can accurately detect the point of transition from water
to product, which is the primary application. Depending on the
degree of solids difference between two materials, it can also
detect a product–to-product transition. And for products such
as skim, 1 percent, 2 percent and whole milk, TBE-10 can act as
a monitor of milk fat percentage and an indicator of product
quality.

The most common calibration entered into TBE-10 includes
points for water, skim milk, 1 percent milk, 2 percent milk,
whole milk and a maximum response standard equal to 20 mA.

The 3A authorized TBE-10 also has uses in the brewing,
pharmaceutical, and juice processing industries. The device
accurately monitors turbidity and product concentration and
can help processors recover as much product as possible before a cleaning cycle begins. It can also help
to ensure equipment adds costly chemicals at the appropriate time.

The TBE-10 sensor assists in determining if fluid should be added to recovery tanks or sent to the drain,
and is an excellent monitor of BOD loading on waste lines. Solid construction means the TBE-10 sensor
stands up to the high temperatures and temperature fluctuations.

Principle of Operation

Utilizing advanced optical technology, TBE-10 sends a beam of infrared light into the process and
measures the backscatter, which is proportional to solids concentration. The device’s internal
microprocessor then converts the scatter to a linearized 4-20 mA output, which easily links to a PLC, DCS
or data logger.

Preliminaries

Standard Shipments

Unless specified otherwise, TBE-10 sensors are shipped with a standard calibration covering a span of
4-20 mA and representing clean water at 4 mA and a maximum white standard at 20 mA. A calibration
document is included in the shipment to inform you of the calibration date and details.

Unpack and Check Contents

Upon receipt of the shipment, carefully remove all items from the shipping package and compare the
contents to the shipping documents.

8

Notice

Also check:

 The TBE-10 sensor and other components for any damage that may have occurred during

shipping.

 To make sure the sapphire lens is clean and undamaged. (If the lens needs to be cleaned, clean

it gently with a mild soap solution and a soft, clean cloth.)

 The sensor’s electrical connector; it should easily mate with the connector pins on the sensor

body.

 To make sure the threaded collar allows a snug, secure fit when fully engaged.

Electrical Connections

TBE-10 has a 5-pin electrical connector. If you purchased the molded, NEMA-6 electrical connector and
cable from Omega, simply connect the cable as provided.

If you are using the Hirschmann connector (Part Number 932 878-100 ELST 512 PG9 (www.hirschmann-

usa.com) and need to make a cable connection, please read the following steps.

The most common wiring scheme for TBE-10 is a 3-wire connection:

 Pin 2 is the mA output
 Pin 3 is the 18 to 24 VDC power supply
 Pin 4 is the ground (negative side of the supply).

A 4-wire connection can also be used to connect TBE-10. In this wiring scheme, connect

 Pin 1 (the negative side of the mA output)
 Pin 2 (positive side of the mA output)
 Pin 3 (18 to 24 VDC power supply)
 Pin 4 (ground).

Pin 1 is the negative side of the mA output and is connected internally to Pin 4. This makes it more
convenient if you want to make a 4-wire connection.

Pin 5, located in the center of the connector is not used.

Once you make the connections inside the electrical connector, tighten the threaded cord grip on the
connector. This helps keep moisture from entering.

9

Notice

Notice

Operation

Once TBE-10 is calibrated and you make the proper electrical connections, the sensor is ready for
operation. Before attaching the sensor to the process line, however, it is advisable to perform a quick
check of the unit’s operation.

You must connect the sensor output to a digital display, multimeter or some other electronics that allows

you to monitor the TBE-10’s mA output.

Applying Power

To view the unit’s internal electronics board, remove the screw lid on the housing (see Figure 3, page

16). When you apply power to the TBE-10 sensor, the green LED on the unit’s internal electronics board
blinks.

When the sensor is operating within the current calibration range, the Green LED on the sensor’s

electronics board blinks alone. When over-range, the Red and Green LEDs blink, and when below range,

the Green and Yellow LEDs blink.

Test Output

1. Place a white paper towel on a table.

2. With the lens facing down, place the sensor on the towel. This should produce an output of

approximately 17 mA. The actual output may range from 16 to 19 mA; this is normal.

3. Lift the sensor straight up, approximately 2 inches above the towel. This should yield a signal of

4 to 4.5 mA.

4. Slowly lower the sensor back to the towel; the mA output will increase as the sensor gets closer

to the towel, eventually reaching approximately 17 mA.

If the sensor performs as stated in the previous test, it is ready for installation. If not, call Omega for
technical assistance.

The TBE-10 is designed to meet CIP requirements. When cleaning the TBE-10, make sure to follow the
same requirements as the installation piping.

Installation

TBE-10 has a conventional sanitary clamp connector that attaches directly to a tee or saddle in the
process line or vessel. TBE-10 comes in standard 1.5, 2, 2.5 and 3 inch sizes.

10

Caution

You can install TBE-10 in a wide variety of configurations, including vertical and horizontal process lines
and tanks. To optimize the performance of the sensor, it is important to:

 keep the deadleg as short as possible on the tee connection, and
 choose an installation site that minimizes air or sediment from collecting on the sensor’s lens.

Deadleg

To minimize deadleg, cut the tee back so the TBE-10 lens is as close as possible to the process stream. In
most cases, it is possible to cut the tee back and have a resulting deadleg of 1 to 2 inches. The shorter
the deadleg the better.

Installation Site

Select an installation site and orientation that minimizes the possibility of air or sediment interfering
with the sensor’s readings.

Vertical

Vertical sections of process lines are excellent installation sites, whether the flow is down or up.

Horizontal

Another excellent installation site is a 90-degree elbow on a horizontal line. In this case, position the
TBE-10 device so the fluid flows directly at the sensor’s lens.

Straight Sections

If installed on a straight section of horizontal process line, place TBE-10 so it looks sideways into the
process stream, not up or down.

Installations Not Recommended

Two installations not recommended are:

 on the top of horizontal process lines, where air has a tendency to accumulate, and
 on the bottom of horizontal process lines, where sediment can accumulate.

Clamp Connection Gasket

The clamp connection requires a gasket between TBE-10 and the tee. In most cases, the customer
provides the gasket and the tee. Customers can purchase these products from Omega if necessary.

Connect

Connect the sensor to the process pipe with the appropriate sanitary gasket and clamp. Orient the
sensor so that the electrical connector points toward the floor (see Figure 2, page 15).

The sapphire lens can be damaged if struck by sharp or hard objects or if the sensor is dropped during

installation. Take care when connecting the sensor to the tee so the lens isn't damaged.

Calibration Verification or Test with Your Samples

The factory normally calibrates TBE-10 according to customer specifications and in most cases, the
factory calibration is sufficient for the application. However, if you want to verify the calibration or
determine the sensor’s response on your samples follow the steps below and record the response.

A common setup is to close off the bottom leg of the tee with an end cap, attach TBE-10 to the middle

leg, and pour the sample in the top leg. (see Figure 2 page 15)

1. Obtain samples of all products that this system will process. You will need enough of each to fill

the internal volume of the test setup.

2. Connect TBE-10 to the required power supply. Attach the sensor to a suitable test stand.

3. Be sure to wire the TBE-10 device properly to either the receiver or to a Multi-meter so you can

view the corresponding signal output from the unit. When you supply power to the TBE-10, the
green LED on the electronics board blinks.

Be careful not to dilute or otherwise contaminate the samples between readings. Also, if the highest

degree of accuracy is desired, make sure the samples are at the same temperature as they will be in the

process line.

4. Starting with the product containing the least amount of solids (lowest turbidity), completely fill

the test volume.

Before taking any readings, make sure to cover the opening of the test cylinder to make sure no external

light can enter the liquid. Any external infrared light could affect readings.

5. Record the output for this product, then move to the next, ending with the product containing

the greatest amount of solids.

When the sensor is operating within the current calibration range, the Green LED on the sensor’s

electronics board blinks alone. When over-range, the Red and Green LEDs blink, and when below range,

the Green and Yellow LEDs blink.

The resulting profile corresponds to the outputs from the unit at each of the various products. Use these
values as the reference for programming a receiver or to verify calibration of the TBE-10 sensor.
Changes in product properties (solids content) are a common cause for discrepancy. If observed, follow
the Calibration Procedure below.

12

Notice

Caution

Calibration Procedure

If you want to adjust the calibration, follow this procedure:

1. Obtain samples of all products that will be processed in this system. If using liquid sample, you

need sufficient volume of each to fill the tee. Calibrate them in increasing order of

concentration. TBE-10 allows you to choose a variety of calibrations, from a 2-point calibration
to a 9-point calibration.

2. Be sure you wire the unit to either the receiver or to a Multi-meter so you are able to view the

corresponding signal output from the unit.

3. Remove the screw lid on the housing by turning it counterclockwise. This allows access to the

electronics board. Refer to Figure 3 on page 16 to locate the Calibration Switch, Entry Key and

Offset Adjustment Keys.

Be careful not to damage the cover o-ring. If damaged, it must be replaced.

4. As shown in Figure 2 on page 15, fill the tee with clean water, or another fluid that you desire to

be the 4 mA reference (if a value other than 4 mA is desired for the base value, please see
SENSOR OFFSET and SPAN CALIBRATION section below).

5. Observe the mA reading that TBE-10 produces with the 4 mA reference sample. If the output is

4 mA, there is no need to adjust. If you desire to change the zero point, turn the calibration
switch to position “0”. Press the UP or DOWN buttons until the desired mA offset reading is
reached. Then press and hold the ENTRY key for approximately two seconds. This stores the
new value as 4mA.

6. Remove the water or optional base product and fill the tee with the next highest solids content.

So as not to introduce error in calibration, it is critical to rinse the tee with water to clean any residue of

the previous product from the face of the sensor and calibration tee.

7. Turn the CALIBRATION SWITCH to position 1. Press and hold the ENTRY key for approximately

two seconds. The sensor output is now set to 20 mA (or the span setting).

8. Repeat step 7, incrementing the CALIBRATION SWITCH by one, until you have calibrated all

points (maximum is to switch position 8). As you add points, each addition becomes the new 20
mA top end. Each previously entered point is linearly re-scaled.

9. In general, a five (5) point calibration is sufficient to provide proper output resolution. You may

use calibration point 0 to 8. Point 9 is reserved for the Sensor Span Output adjustment,
described below.

10. To obtain output values, place the sensor again into each of the test liquids. With each product,

record the resulting current output from the transmitter. The resulting profile corresponds to
the outputs from the unit at each of the various products.

11. These values can now be used to program a receiver.

13

Caution

Caution

Caution

Notice

For correct signal output scaling, make sure to leave the switch setting at the last calibration point
during operation.

Sensor Offset and Span Calibration

The TBE-10 sensor is typically scaled at the factory with 4 mA output for the “base reference” material
(first calibration point) and 20 mA for the material with highest turbidity value (last calibration point).
For most applications, it is recommended that the unit be used in this configuration. The following
procedure illustrates steps to verify or modify these values.

1. Remove the screw lid on housing.

Be careful not to damage rubber o-ring. If o-ring is damaged it must be replaced.

1. Refer to the Figure 3 on page 16 to locate the Calibration Switch, Entry Key and Offset

Adjustment Keys.

2. If you wish to change the span value, place the Calibration switch in Position “9” and press the

“UP” or “DOWN” offset adjustment keys until you obtain the desired value; then press and hold
the ENRTY key for approximately 2 seconds to store value.

3. If you wish to change the “base reference” value, place the Calibration switch in Position “0” and

press the “UP” or “DOWN” keys until you obtain the desired value; then press and hold the
ENTRY key for approximately 2 seconds.

Be sure to set the switch back to the position used for the last calibration value or the output scaling will

be incorrect

Clean Sweep

Clean Sweep is a feature which resets the sensors programmed values back to factory defaults. This is
usually used in cases where someone wants to completely recalibrate a unit. To Clean Sweep a unit,
with the unit powered up, press and hold the UP, DOWN & ENTRY keys at the same time for about 3-5
seconds. Once the buttons are pushed, the Green LED will turn off and then back on solid, after which
the Red LED will start to blink. Once the Red LED blinks, release the keys. When Clean Sweep has been
completed the Green LED will flash. The Red LED may also blink which is ok.

Once Clean Sweep has been performed, there is no way to get the previous values back.

Figure 2: TBE-10 Sensor attached to a sanitary T, electrical connection facing floor

Figure 4 on page 17 shows an example of a multi-point calibration. For this example, milk samples were
used. Water = 4 mA, skim milk = 8 mA, 1% milk = 12 mA, 2% milk = 16 mA and whole milk = 20 mA. The
calibration selector switch was at 0 position for water, 1 position for skim milk, 2 position for 1% milk, 3
position for 2% milk and 4 position for whole milk.

Figure 5 on page 18 shows a slightly different example of a multi-point calibration. In this case, a dairy
customer wanted a greater degree of sensitivity near 1% milk fat; a 6-point calibration was used, which
emphasized the 1% to 1.3% milk fat concentration. All that was necessary was to prepare samples of the
proper concentration. The TBE-10 calibration linearizer divided the 4-20 mA span into five sections of

3.2 mA each, including the key range in the middle of the graph.

If questions arise at any time, please contact Omega.
