TQ412 111-412-000-013-A1-B1-E050-F2-G050-H05

Product Overview

TQ412 111-412-000-013-A1-B1-E050-F2-G050-H05 is a high-performance, non-contact eddy current displacement sensor produced by Parker Meggitt. The TQ412 product belongs to the close measurement system product line and is specifically designed for precisely measuring the relative vibration and axial displacement of rotating mechanical shafts in harsh industrial environments.

The model code is parsed as follows

111-412-000-013    Basic product number, indicating a TQ412 series sensor.

A1                         Environmental option, indicating the standard industrial version, without explosion-proof certification

B1                         Thread type, M10 x 1 metric thread

E050                      Built-in cable length, an integrated FEP coaxial cable of 5.0 meters ± 0.5 meters

F2                         Optional protection, a flexible stainless steel hose with FEP sheath

G050                     Flexible hose length, a protective hose that is 5.0 meters long.

H05                       Total System Length, this sensor is designed to form a complete measurement chain of 5 meters. In this configuration, since the built-in cable is already 5 meters, there is usually no need to extend the cable EA402 additionally.

TQ412 111-412-000-013-A1-B1-E050-F2-G050-H05 is a Reverse Mount sensor, characterized by the signal cable being led out from the rear of the sensor instead of passing through the mounting thread. This design is particularly suitable for applications where installation space is limited, wiring cannot be done from the front end, or where cables need to be led out along a specific path, such as inside bearing housings, in narrow casings, or near couplings.

This order is configured with specific parameters

Thread                                  M10 x 1 metric

Built-in cable length E             5.0m ± 0.5m

Optional protection F2             Flexible stainless steel hose + FEP sheath

Advantages of FEP sheath       TQ412 is resistant to almost all chemicals, has extremely low permeability to liquids, gases and moisture, and also features flexibility, a low coefficient of friction and excellent mechanical toughness.

Flexible hose length G             5.0m. According to the ordering rules, the maximum length = the length of the built-in cable - 200mm = 4.8m. Here, G050 should be understood as the effective protective length that covers most of the cables.

Total system length H             5 meters

Product functional features

The core design of the reverse-mounted structure for solving extreme installation problems

The physical layout enables the signal cable to be axially led out from the tail of the sensor body instead of passing through the front end of the thread. This enables the cable to be freely laid out along the axial or radial direction after the sensor is installed, avoiding the problem that traditional upright sensors cannot be wired due to insufficient space in front.

Typical application scenarios

TQ412 111-412-000-013-A1-B1-E050-F2-G050-H05 can be installed in the blind hole inside the bearing housing, with no operating space in front.

A narrow area close to the coupling, sealing cavity or the inner wall of the casing.

In situations where multiple sensor cables need to be led out from the same side to simplify the layout of the cable tray

The engineering advantages are reflected in significantly reducing the restrictions of mechanical design on monitoring points, transforming the originally "unmeasurable" key positions into "measurable" ones, and enhancing the coverage rate of overall machine status perception.
