IQS453 204-453-000-011 / IQS453 204-453-000-021 share the same long-range conversion behaviour, while their five-metre and ten-metre calibrations keep each conditioner aligned with its assigned TQ4x3 chain.

1. 01

   Twelve-millimetre measurement span

   Both IQS453 204-453-000-011 / IQS453 204-453-000-021 condition the response of a TQ4x3 probe across a nominal 12 mm range. The 1.33 mV/µm scale relates target displacement to the three-wire voltage delivered by the complete chain.

2. 02

   Static and dynamic response

   The DC component from IQS453 204-453-000-011 / IQS453 204-453-000-021 represents the steady probe-to-target gap. Response through 20 kHz carries changing displacement so one signal path serves position and vibration measurement.

3. 03

   Supply and load behaviour

   Each IQS453 204-453-000-011 / IQS453 204-453-000-021 receives -20 to -32 VDC and normally draws 13 ±1 mA. The voltage output has 500 ohm impedance and short-circuit protection for the connection to the monitoring input.

IQS453 204-453-000-011 / IQS453 204-453-000-021 join four distinct parts of the channel: the TQ4x3 probe, the calibrated cable path, the conditioner electronics and the receiving voltage input.

1. 01

   Probe excitation path

   The female coaxial connector on IQS453 204-453-000-011 / IQS453 204-453-000-021 joins the TQ4x3 transducer to the HF modulator. The conditioner drive creates the probe field, and the same connection returns the impedance change caused by target movement.

2. 02

   Conditioning and terminal path

   The modulator/demodulator inside IQS453 204-453-000-011 / IQS453 204-453-000-021 converts the returned probe response before it reaches the OUTPUT terminal. COM provides the signal reference, while the -24 VDC terminal feeds the conditioner circuitry.

3. 03

   Calibrated system length

   IQS453 204-453-000-011 belongs to the five-metre TQ4x3 path and IQS453 204-453-000-021 belongs to the ten-metre path. Keeping that electrical length with the matching conditioner preserves the relationship between probe field, demodulated voltage and receiving input.
