TEST & MEASUREMENT

Top of 1020

1010 ADC (top) and 1020 8 CHANNEL MULTIPLEXER

for MEASUREMENT SYSTEMS Ltd, 1981.

A single ADC will drive up to 32 Multiplexers either via the DIN41612 R65 bus or via a 5 wire daisy chained link in a distributed system. Adding a communications card and a host PC with a Basic Interpreter results in a complete 256 channel Data Acquisition System. The ADC has on board firmware for Volts, Temperature, Strain and 4-20mA current, giving linearised Engineering unit results for strain, PRTs and 5 types of thermocouple. Each Multiplexer has on-board temperature sensing for cold junction compensation. Sensitivity is 0.75μV at 16 channels/s and 16 bit resolution with mains integration; Standard deviation is less than 0.75μV. A 160ch/s mode gives reduced resolution of 12 bits and sensitivity 6 μV. A 1987 update is still in production (by TE for MSL) and is used by Geoservices (Paris) in oil exploration.

 

 

Datadec

The TE701 "DATADEC" CASSETTE DATA RECORDER

for DATALINE Srl, ITALY; 1977

At this time floppy disc drives were still exotic and cassettes were widely used for data storage. The Datadec used a TE patented principle to give relatively high speed high integrity data recording. The Datadec had a circular buffer and ran the cassette as necessary dividing the data into blocks with CRC error checking. Data I/O was via RS232, with five switchable data rates, plus parallel and current loop interfaces. The case was to match an existing K&N Acoustic Coupler.

 

 

Demo Box

TE2829 DATA ACQUISITION

SYSTEM DEMONSTRATOR

for RACAL INSTRUMENTS, 1998

 

A convenient way to demonstrate a Data Acquisition System at Trade Exhibitions or at customer's premises.

It provided two thermocouple inputs, eight digital inputs, LED indicators for eight digital outputs plus voltage, ramp and frequency outputs of various polarities and amplitudes which could be fed to different input channels.

 

 

Launch Control Test Equipt

STTE for a MISSILE LAUNCH CONTROL SYSTEM

for SIEMENS PLESSEY SYSTEMS, 1992

 

Provides dc Power for the UUTs, monitors a 50 way parallel bus and simulates and monitors the signals to eight Launch Control Panels.

 

 

TE503 Computing Tacho

TE503 COMPUTING TACHOMETER

for MYTCHETT SCIENTIFIC INSTRUMENTS, 1975

 

A reciprocal time tachometer that used a Texas Instruments calculator chip for the processing. The Optical sensor shone onto a rotating part and the thumbwheel used to define the number of reflecting bars per revolution (minimum=1). This technique gives a much higher speed of measurement than a pulse-counting system.

 

 

TE401 Record Deck Tester

TE401 RECORD DECK TESTER

for GLENBURN ENGINEERING, 1974.

 

By the use of a standard test record, the unit gave rapid go/nogo testing of motor-run, set-down point, presence of both channels, balance, wow and flutter, rumble and speed.

This was TE Electronics' first product.

Glenburn Engineering was set up by Dr McDonald an attempt to challenge BSR's then dominance of the world Record Deck market. McDonald was the founder of BSR but had been removed from the board as he was deemed too old. Sadly, the venture failed.
