Analog Signal Tension Amplifier DC24V With Two Load Sensors High Precision Tension Transducer

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

Features:

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.

Features:

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 sensor.

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.

Product category:

STA - 05B : Using strain - gauge sensor , input signal r - ange - 5mv ~ + 10mv.

STA - 05C : Using differential sensor , input signal ran - ge - 100mv~ + 200mv

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.

[2] 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.
