TQ402 111-402-000-012 A1-B1-C075-D000-E050-F2-G050-H05

Product Overview

This product is the TQ402 111-402-000-012 A1-B1-C075-D000-E050-F2-G050-H05 non-contact eddy current displacement sensor produced by Meggitt (Vibra-Meter ®), which is an intrinsically safe product specially designed for potentially explosive environments. The Proximity Transducer belongs to the proximity measurement system composed of TQ402/TQ412, EA402 and IQS900, which is used for continuous and precise monitoring of the radial vibration and axial displacement of rotating machinery in hazardous areas.

This specific order number indicates that this sensor not only has the high performance of the TQ402 series, but also has passed the strict intrinsic safety "Ex i" certification, and can be safely used in Zone 0, 1, 2 of environments with flammable and explosive gases such as petroleum, chemical industry, and natural gas. TQ402 configuration includes a 75mm housing length, a 5-meter integrated cable, and a flexible stainless steel hose with an FEP sheath for protection. TQ402 111-402-000-012 A1-B1-C075-D000-E050-F2-G050-H05 is a highly reliable and safe solution designed for demanding application scenarios.

Product specifications and parameters

Detailed configuration analysis of the order number

A1              Environmental Standard - Intrinsically safe type (Ex i). This is the core difference from the previous model, indicating that this sensor complies with the intrinsic safety explosion-proof standard.

B1              Shell thread - M10 × 1 metric thread, highly versatile and easy to install.

C075          Shell length - 75mm. A longer shell offers better mechanical stability and support on thicker mounting walls.

D000          Threaded length -0mm, with threads running through the entire housing.

E050          Integrated cable length - 5.0 meters.

F2              Optional protection - Flexible stainless steel hose with FEP sheath. Provide the highest level of mechanical protection (impact resistance, pressure resistance, wear resistance) and chemical corrosion protection for cables.

G050           Flexible hose length - 0.5 meters. Protect the key cable sections close to the sensor head.

H05            Total system length - 5 meters.

Key performance and physical parameters:

Measurement principle             Eddy current effect

Linear measurement range       2 mm or 4 mm (depending on the IQS900 Settings)

Sensitivity                               8 mV/µm (2mm range) or 4 mV/µm (4mm range) - voltage output

Frequency response                 DC to 20 kHz (-3 dB)

Operating temperature             -40°C to +180°C (probe) -40°C to +120°C (Cables and connectors)

Linearity                                 Referring to the performance curve in the data sheet, the typical error is extremely small.

Protection grade                      IP68 (sensor head and integrated cable).

Explosion-proof certification      Complies with Ex ia IIC T6... The T3 Ga standard is applicable to hazardous areas in multiple regions such as Europe, international (IECEx), and North America. Certificate number such as LCIE 11 ATEX 3091X.

Target material                        Magnetic conductive steel (such as AISI 4140).
