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.
