IQS450 204-450-000-001 A1-B21-H05-I0 Signal Conditioner

IQS450 204-450-000-001 A1-B21-H05-I0 Signal Conditioner

Description

The TQ401, EA401 and IQS450 form a proximity measurement system from Meggitt’s vibro-meter® product line. This proximity measurement system allows contactless measurement of the relative displacement of moving machine elements.

TQ4xx-based proximity measurement systems are particularly suitable for measuring the relative vibration and axial position of rotating machine shafts, such as those found in steam, gas and hydraulic turbines, as well as in alternators, turbocompressors and pumps.

The IQS450 signal conditioner contains a highfrequency modulator/demodulator that supplies a driving signal to the transducer. This generates the necessary electro-magnetic field used to measure the gap. The conditioner circuitry is made of high-quality components and is mounted in an aluminium extrusion.

Meggitt IQS450 204-450-000-001 A1-B21-H05-I0 Specifically designed for mechanical protection and condition monitoring applications, Its core function is to form a calibrated proximity measurement system with the TQ401 proximity sensor and EA401 extension cable. Based on the eddy current principle, it enables non-contact measurement of relative displacement in moving mechanical components, outputting voltage/current signals proportional to the gap distance. This provides precise data support for vibration and position monitoring of rotating machinery. 

Features

Precision Measurement and Wide-Band Response: Supports a 2mm linear measurement range (typical 0.2-2.2mm) with sensitivity up to 8mV/µm. Frequency response spans DC to 20kHz (-3dB), enabling precise capture of critical parameters such as shaft vibration and axial position to meet high-precision monitoring requirements.

Multi-scenario Adaptability: Supports standard (A1) environmental deployment, accommodates a total system length of 5m (H05), operates within -35°C to +85°C, and features IP40 protection. Withstands industrial fluctuations in temperature and humidity, vibration (2g peak, 10-55Hz), and shock (15g peak), ensuring stable, uninterrupted operation.

Safety, Reliability, and Compliance: Complies with CE, EAC, and other regulatory standards; RoHS compliant; meets EN 61000 series EMC requirements. High-quality components ensure short-circuit protection (45mA short-circuit current) and 500Ω output impedance for stable, resilient signal transmission.

Convenient Integration and Maintenance: Features an injection-molded aluminum housing with a net weight of approximately 140g. Supports M4 screw mounting or TSH 35 DIN rail installation via the MA130 adapter (compatible with TH 35-7.5/15 standard rails). Equipped with a self-locking mini coaxial input connector and 3 screw terminal outputs/power supply connectors (supporting up to 2.5mm² wires), ensuring secure wiring and easy installation/removal.
