More Information

Overview Manuals Sensor Bridge Calibration Path Output Loading Signal Filtering

Features:

  • Excites one or two 350 ohm tension sensors connected to one measuring channel.
  • Converts the bridge signal into simultaneous voltage and current outputs.
  • Uses adjustable zero, gain and filtering to match the mechanical measuring chain.
The sensor bridge, amplifier and two analog outputs form one continuous measurement path.

Calibration relates a known mechanical force to a defined controller input value.

Shielding, grounding and filter selection determine how interference and process dynamics appear at the output.

The FMS EMGZ306A Single-Channel Analog Tension Measuring Amplifier may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Connecting the force sensors to one channel

  • Excitation: The amplifier supplies 5 V DC to the connected bridge.
  • Parallel sensors: Two equal 350 ohm sensors can share the excitation and signal path.
  • Signal polarity: The differential leads determine whether increasing tension raises or lowers the output.
  • Shield termination: The cable shield follows the earth arrangement shown for terminal 3.

Relating known force to analog output

  • Zero point: The unloaded mechanical condition establishes the electrical baseline.
  • Reference load: A known tension is applied before gain is adjusted.
  • Gain setting: The output span is matched to the controller range.
  • Recheck: Zero is verified again because offset and gain adjustments interact.

Keeping both analog outputs within range

  • Voltage output: The receiving input presents at least the documented minimum resistance.
  • Current output: The total loop resistance remains below the specified maximum.
  • Simultaneous use: Voltage and current paths can feed separate receivers at the same time.
  • Common reference: Output references are wired according to the receiving-device circuit.

Balancing response speed and stability

  • Process motion: Mechanical vibration can add rapid changes to the sensor signal.
  • Capacitor choice: The external capacitor sets the documented low-pass frequency.
  • Response delay: Lower bandwidth produces a steadier but slower output.
  • Test step: A known tension change confirms that filtering still meets control timing.
Description
FMS EMGZ306A is a single-channel analog tension measuring amplifier for one or two 350 ohm force sensors connected in parallel. It supplies the sensor bridge and changes the resulting millivolt signal into simultaneous voltage and current outputs for a controller or display.

Sensor excitation leaves EMGZ306A through the bridge-supply terminals while the differential return signal enters the adjustable amplifier stage. Zero and gain settings align the unloaded and reference-tension conditions with the required analog output scale.

The output stage of EMGZ306A provides a ±10 V path and a selectable 0/4 to 20 mA path at the same time. Each receiving device must meet the documented load resistance so neither output is forced outside its operating range.

Installed on a DIN rail, EMGZ306A uses shielded twisted-pair sensor wiring and the specified earth terminal to control interference. An external filter capacitor trades response speed for additional signal smoothing when the mechanical process produces rapid tension fluctuations.

Technical notes
Before calibrating FMS EMGZ306A, verify sensor polarity, bridge excitation, earth terminal 3 and the selected zero signal.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does FMS EMGZ306A output move in the wrong direction as tension rises?
For FMS EMGZ306A, check force-sensor orientation and differential signal polarity before changing the gain setting.
How is EMGZ306A calibrated without confusing zero and span?
Set the EMGZ306A zero at the unloaded condition, apply a known reference force, adjust gain and then recheck zero.
What should be checked when the EMGZ306A current output saturates?
Verify EMGZ306A supply voltage, loop resistance, 0/4 mA selection, sensor signal and reference scaling at the receiving input.
Can one FMS EMGZ306A accept two force sensors?
Yes. FMS EMGZ306A can excite two documented 350 ohm sensors in parallel when their wiring and mechanical load sharing match.
Why is an EMGZ306A signal noisy after cabinet installation?
Inspect EMGZ306A shield termination, earth path, sensor-cable routing, supply noise and filter capacitor before altering calibration.
Which details are needed to replace FMS EMGZ306A safely?
Record FMS EMGZ306A sensor count, bridge polarity, zero, gain, filter, output selection and controller scaling.
