Measuring Amplifiers Tension Amplifier DC24V Connecting Two Load
Sensors In Printing Machine
Measuring amplifiers ensure a stable bridge supply voltage, They
amplify the output signal of the load sensors to a standard signal
STA-05 Intelligent tension transducer
1. Key intelligent operation,outside without adjust potentiometer.
2. Hardware and software to restrain power frequency interference,
output steady and reliable.
3. Adapt DIN-rail mounting,easy and convenient.
4. Adapt SMT,small size,light weight.
5. Tension controller with STS ans STSA for option.

32 bit CPU guarantees high speed, precision, ant-ijamming
capability and ensures reliability.
The outside has no adjustable potentiometer.
The tension sensor can select Differential sensor or Strain- gauge
0~ 10V/ 0~ 5V and 0~ 20mA output signals can be p-rovided to PLC
and display instrument.
Use dispensing technology, small volume, light wei-ght.
Using DIN rail mounting, simple and convenient.

Notes of Using Tension Detector
1. Set screws A and B should not be too long when the bearing
houses are installed on the detector. Other-wisethe force could not
cause relevant deformations and displacements on the detector. Use
spherical u-niversal bearing houses to avoid the detectors on b-oth
sides interacting on each other, causing errors on calibration.
2. The wrap angle of film over detector reel shouldn’t be larger
than 120, around 60°would be perfect. The s-ignal detected by
detector would be too weak to con-trol tension effectively with a
large wrap angle.
3. The load force caused by film tension should not poi-nt to the
screw ends of tension detector. Otherwise t-here will be very low
or even no output.
4. The screw ends of tension detector should point upw-ards when
installed on a wall.
5. If the film is pulled cross the reel from below, the fo-rce
caused by film tension pulls but not pushes the tension detector.
So the negative and positive detec-tor signal wires should exchange
when connected to the controller terminals.
- LED2 turns red, LED1,LED3 red twinkle, there are se-
veral ways as follows:
[ 1] Tension sensor connection drops or poor contact. LED1 twinkle
shows left tension sensor has problem, LED3 twinkle shows right
tensioin sensor has problem, ple-ase check sensor connection.
 The difference of signal between left sensor and right sensor
is too large. When the LED twinkle , it shows the sensorsignal is
too small,please ajust the sensor or change it.
- LED2 turns green,LED1,LED3 alternately twinkle,it shows zero
alignment and calibration has problem,t-his reason refer to part 9.
- . Zero calibration operation:
- . Machine power off, there is no film or film is loose.
- . Press “Zero alignment” button for 3~5 sec,LED1 tu-rns on.
- . When LED1 starts twinkle,loosen “Zero alignment” button,the
twinkle stops,LED1 turns off, so complete zero alignment.
