7.2.4. Transmitters (load cells, pressure sensors, etc.)
The following settings can be made for measuring transmitters:
Voltage source
Meas.
mode
10 VDC
Excitation
12 VDC
Transmitter excitation
Meas. rate
0,1; 0,2; 0,5; 1; 2; 5; 10;
20; 50; 100; 200; 400;
600; 1200 readings/s
Number of measurement readings recorded per second.
Caution
: reduced accuracy for 50 or more readings/s.
Units
Any
The user can specify any units required. 6 characters are
available.
Scal.low
Lower calibration value for 2-point scaling can be entered
here or taught (using
[F3]
"teach-in" function).
The teach-in function only works if the sensor is connected
and the correct channel parameters have been set.
Cal.hi
Upper calibration value for 2-point scaling can be entered
here or taught (using
[F3]
"teach-in" function).
The teach-in function only works if the sensor is connected
and the correct channel parameters have been set.
Scal.low
The lower scale value for 2-point scaling (typical value = 0)
can be entered here.
Scal.hi
The upper scale value for 2-point scaling (typically 100%
of sensor measurement range) can be entered here.
7.2.5. "burster TEDS" sensors
Note:
"TEDS" stands for
T
ransducer
E
lectronic
D
ata
S
heet.
The TRANS CAL model 7281 includes the facility to use sensors that have the "burster TEDS" option.
A sensor that has the "burster TEDS" option lets you set up the measurement chain in use easily
without having to enter the values manually in the "Channel setup" menu. This lets you operate
different sensors on the TRANS CAL model 7281 quickly and easily without having to configure each
one manually.
Information from "burster TEDS" data:
• Manufacturer
• Sensor type
• Serial number
• Sensor test date / time
• Rated value (measurement range)
• Zero point
• Output sensitivity
• Excitation
• Calibration shunt used
