IQS452 204-452-000-211 supplies the TQ4x2 probe, recovers the eddy-current response and delivers a conditioned three-wire voltage to the monitoring input.

1. 01

   High-frequency excitation

   The modulator in IQS452 204-452-000-211 sends a high-frequency drive to the TQ4x2 transducer. The probe coil uses that drive to establish the electromagnetic field at the conductive target.

2. 02

   Gap-signal recovery

   Target movement changes probe impedance, and the demodulator in IQS452 204-452-000-211 converts that change into a displacement-related signal. The DC component represents static gap while the changing component represents motion.

   Voltage-output handoff

   IQS452 204-452-000-211 presents the conditioned result on its three-wire output at 8 mV/µm. The 500 ohm output then feeds the compatible voltage input of the monitoring electronics.

The 2 mm span, five-metre calibrated chain and electrical limits define how IQS452 204-452-000-211 behaves from the probe connection to the output terminals.

   Range and frequency path

   IQS452 204-452-000-211 maps the matched TQ4x2 chain across a nominal 2 mm range. Its DC to 20 kHz response carries both shaft position and dynamic displacement through the same conditioner.

2. 02

   Matched cable calibration

   The five-metre probe-and-cable path belongs to the calibration of IQS452 204-452-000-211. Changing the electrical length changes the relationship between the TQ4x2 coil and conditioner electronics.

   Supply and output limits

   IQS452 204-452-000-211 operates from -20 to -32 VDC and draws 13 ±1 mA under normal conditions. Its voltage output is short-circuit protected, with a specified 45 mA short-circuit current.
