Vibro meter TQ902 Installation and UsageVOGI
1.TQ902 111-902-000-011 Installation points
Component matching
Requires EA902 extension cable and IQS900 signal conditioner, optional stainless steel hose or FEP sheath protection cable.
Mechanical installation
Thread fixation: Select the thread specification (such as M10×1) according to the device interface, and tighten the connector by hand until it is locked to avoid overtightening.
Cable bending: The minimum bending radius of the integrated/extended cable is 20 mm, and the stainless steel hose is 50 mm.
Total length configuration: Supports 1 m, 5 m, and 10 m system lengths (integrated + extension cable), and the electrical tuning length must be ensured (such as 5 m system ≥4.4 m).
Explosion-proof environment
For use in Ex areas, the corresponding explosion-proof model (Ex ia/nA) must be selected. When the signal conditioner is installed in Zone 2, it must be placed in an IP54 housing.
2. TQ902 111-902-000-011 Electrical connection
Power supply
IQS900 power supply: −18 to −30 VDC (current output) or −19 to −30 VDC (voltage output), do not reverse polarity.
Signal calibration
Standard temperature +23°C ±5°C, target is VCL 140 steel, non-standard materials require customized calibration curves.
Verify output range (e.g. B21 model: 0.15–2.15 mm gap corresponds to −1.6 to −17.6 V).
Anti-interference
Keep the cable away from strong electromagnetic sources and match the impedance of the monitoring system (voltage ≥50 kΩ, current ≤350 Ω).
3. TQ902 111-902-000-011 Precautions for use
Environmental requirements
Operating temperature −40°C to +180°C, Ex area ≤+195°C, protection level IP68 (sensor head).
Maintenance inspection
Regularly check whether the cable connection is loose, whether the hose is damaged, and monitor drift at high temperature (>5% requires calibration).
Troubleshooting
No signal: Check the power supply, connector polarity and contact.
Unstable signal: Eliminate electromagnetic interference or replace the faulty component (sensor/cable/conditioner).
