What is TEDS?

"Plug and play sensor hardware and software make configuring a smart TEDS sensor as easy as

plugging a mouse into a PC. The technology has greatly improved efficiency and productivity by

completely eliminating manual sensor configuration."

Basic concept

TEDS is at the heart of the new universally accepted IEEE 1451.4 standard for delivering Plug and Play

capabilities to analogue measurement and test instruments. In essence, information in a Transducer

Electronic Data Sheet provides interfacing devices with the critical sensor calibration information in order

to perform accurate and precise measurements every time.

TEDS works in a similar way in which USB computer peripherals immediately work as they are connected.

TEDS enabled equipment maybe swapped and changed without recalibration, saving time and money.

TEDS holds information such as a sensor manufacturer, model and serial numbers, and more importantly all

the calibration settings determined by the manufacturer.

How it works

Plug and play is a data acquisition technology that can simplify the configuration of automated measuring

systems by making a sensor’s unique identification data available electronically. As implemented according

to IEEE P1451.4, data in the form of a transducer electronic data sheet (TEDS) is burned on an electrically

erasable programmable read-only memory (EEPROM) chip located on the sensor, so when a properly

adapted signal conditioner interrogates the sensor, it can interpret the self identification data. This

technology provides a great benefit by eliminating the need for paper calibration sheets. In addition, it

can simplify labeling and cabling problems, as well as inventory control issues; by letting you burn location

data onto the chip when installing a sensor. And because all sensors produced according to the standard

will carry the same basic identically formatted self-identification information, you will be able to mix and

match sensors and applicable signal conditioners across manufacturers.

Advantages

Plug and play sensors are revolutionizing measurement and automation. With Transducer Electronic Data

Sheets (TEDS), your data acquisition system can detect and automatically configure sensors. This

technology provides:

•Reduced configuration time by eliminating manual data entry

•Better sensor tracking by storing data sheets electronically

•Improved accuracy by providing detailed calibration information

•Simplified asset management by eliminating paper data sheets

•Reliable sensor location by identifying individual sensors electronically

Introduction

The PSD Portable Strain Display Load Cell/Force transducer readout is a microprocessor based portable

instrument designed to interface with any full bridge sensor with an output sensitivity of up to 50mV/V.

Bridge resistances from 85Ωupwards can be used with the PSD.

Configuration and calibration of the PSD is achieved using the front panel push buttons to navigate through

a very simple menu structure.

User functions available on the PSD include:-

Range Selection

Display Hold/Freeze

Gross/Net indication selection

Peak Hold selection

Trough Hold selection

Shunt Cal check

The PSD is powered by two internal non-rechargeable AA alkaline batteries.

Electrical Connection Information

Sensor Connections

The standard sensor connection is a 5 pin 723 series Binder connector. The wiring for this is detailed

below:-

PIN 1 +ve Excitation

PIN 2 -ve Excitation & TEDS Common

PIN 3 +ve Signal

PIN 4 -ve Signal

PIN 5 TEDS

RS232 Port Connections

If the PSD has been ordered with the optional RS232 output, then this will be available via a 8 pin 723

series Binder connector. The wiring for this is as detailed below:-

PIN 1 Tx

PIN 2 Rx

PIN 3 Gnd

Note: PINS 4 to 8 not connected

Internal Connections

It may be necessary from time to time to know what the internal connections are. For example, if you

disturb some of the connections whilst trying to insert the range legends, or if you need to change the

internal shunt calibration resistor. These are shown below for reference only:-

There are six push buttons on the front panel of the PSD, which are available for use in normal operation.

Each of these is described below:-

Front Panel Button

Function of Button in Normal Operation Mode

To switch the PSD ON or OFF press and hold the button

The RANGE button allows the user to toggle between two independent

scales. An annunciator highlights the range that has been selected.

The HOLD button allows you to hold/freeze the current display value when

the button is pressed. Pressing the HOLD button again releases the display.

The HOLD annunciator is illuminated when in the HOLD mode, and the

display will flash, to alarm further that the user is not viewing instantaneous

display values.

The

GROSS/NET

button, when pressed, allows the user to toggle between

displaying the Gross or Net display values. This can be useful in many

applications where it is necessary to display the change in display value from

a certain part of the measurement range. When in NET mode the NET

annunciator is lit. When in GROSS mode, the NET annunciator is not lit.

The SHUNT CAL button allows the user to press this at any point in time.

The standard unit shunts a 100kΩresistor across the negative excitation and

negative signal connections. If this is performed at the end of the calibration

procedure, then a figure can be noted, so the user can check calibration

accuracy or connection integrity. The button has to be held down to

operate. When held down the SHUNT CAL annunciator is lit and the display

will flash, to alarm further that the user is not viewing instantaneous display

values.

When the PEAK button is pressed the display will show the last Peak reading.

To reset the Peak readings press the PEAK and TROUGH buttons

simultaneously. When in PEAK mode the PEAK annunciator will be lit and

the display will flash, to alarm further that the user is not viewing

instantaneous display values. To turn off Peak mode press the

PEAK

button.

When the TROUGH button is pressed the display will show the last Trough

reading. To reset the Trough readings press the TROUGH and PEAK buttons

simultaneously. When in TROUGH mode the TROUGH annunciator will be lit

and the display will flash, to alarm further that the user is not viewing

instantaneous display values. To turn off the Trough mode press the

TROUGH

button

Menu Structure

The PSD has two menus, details of which are outlined below:-

A CONFIGURATION MENU, which enables the user to tailor the operation to meet a specific application

requirement. The values selected in the CONFIGURATION MENU are completely independent for each

range.

A Calibration Menu, which is used to calibrate each of the two ranges with independent scales, as well as setting the display resolution for each range.
