VIBRO-METER HIGH-TEMPERATURE PROXIMITY SENSORS

TQ912 & TQ902

 
PRODUCT 01
TQ912
Reverse-mount proximity sensor for installations where access and available mounting space favor rear-side assembly.
PRODUCT 02
TQ902
Conventional-mount proximity sensor available with metric or imperial threads and an integral coaxial cable.
PRODUCT 01 / TQ912

Reverse-Mount Sensing for Restricted Machine Access

TQ912 Proximity Sensor

TQ912 uses the eddy-current principle to measure the distance between the sensor tip and a conductive machine target without physical contact. Its reverse-mount construction addresses applications where conventional front-side mounting is difficult.

Mounting form: Reverse mount
Conditioner family: IQS900
Typical tasks: Shaft vibration, axial position and gap
 
Sensing principle Non-contact eddy current
Mechanical distinction Reverse-mount sensor body
Linear range options 2 mm or 4 mm as a complete configured chain
Frequency response DC to 20 kHz (-3 dB) with the matched chain
Temperature capability High-temperature service; configuration dependent, with short-duration capability up to +220 deg C
Complete chain TQ912 + EA902 where required + IQS900
PRODUCT 02 / TQ902

Conventional Threaded Mounting for Proven Shaft Measurement

Sensing principle Non-contact eddy current
Mounting arrangement Conventional threaded installation
Thread options Metric or imperial according to the complete order code
Sensor cable Integral coaxial cable; exact length and connector must be verified
Typical tasks Relative shaft vibration, axial position, static gap and speed service
Complete chain TQ902 + EA902 where required + IQS900
 
TQ902 Proximity Sensor

TQ902 is the conventional-mount version of the high-temperature sensor family. The sensor head, integral coaxial cable, optional EA902 extension and IQS900 conditioner form one calibrated electrical chain for machinery monitoring.

Ordering focus
Confirm thread, cable length, connector, range, approvals and the matched IQS900 configuration.
FAMILY AND SYSTEM RELATIONSHIP

Same Measurement Principle, Different Mounting Geometry

TQ912 and TQ902 are not a comparison-only pair. Each is a complete product choice for a specific installation. Their electrical performance depends on the matching EA902 cable arrangement, IQS900 conditioner and configured monitor input.

SELECTION POINT TQ912 TQ902
Mounting concept Reverse-mount construction Conventional threaded construction
Best installation fit Restricted access or rear-side mounting Standard probe brackets and threaded holes
Thread selection Confirm reverse-mount mechanical code Metric or imperial options by order code
Electrical chain TQ912 / EA902 / IQS900 TQ902 / EA902 / IQS900
Replacement rule Match the complete sensor code, mounting geometry, cable, range, approvals and conditioner. Do not substitute by sensor appearance.
APPLICATION ADVANTAGES

Why the TQ9xx Sensor Chain Is Used

01 / NON-CONTACT

The sensor observes a conductive target without wear-producing contact, supporting continuous shaft measurement.

 
02 / HIGH TEMPERATURE

The sensor family is intended for elevated-temperature machinery locations where standard proximity probes may not be suitable.

 
03 / MOUNTING CHOICE

Conventional and reverse-mount forms allow the sensing principle to be applied to different machine-access conditions.

HOW TO SELECT
1. Inspect access

Choose reverse or conventional mounting.
> 2. Match mechanics

Confirm thread, body form and probe reach.
> 3. Verify cable

Check integral cable and EA902 length.
> 4. Confirm range

Match 2 mm or 4 mm chain configuration.
> 5. Match electronics

Verify IQS900 output and monitor input.
Quick decision: select TQ912 when the machine requires reverse mounting; select TQ902 for conventional threaded mounting. Then verify the full electrical chain before purchase.

PURCHASING FAQ

Five Questions to Resolve Before Ordering

01
What is the practical difference between TQ912 and TQ902?
TQ902 is intended for standard-mount installation and TQ912 for reverse-mount installation. Their sensing specifications and performance are otherwise the same.
 
02
Can TQ912 and TQ902 be connected to any signal conditioner?
They are designed for a matched chain using an EA902 extension cable when required and an IQS900 conditioner. Range, sensitivity and total system length must be compatible.
 
03
What should be checked before ordering TQ912 or TQ902?
Confirm mounting direction, metric or imperial thread, body dimensions, integral cable length, optional flexible-hose or connector protection, environment approval and total chain length.
 
04
Are TQ912 and TQ902 suitable for high-temperature machinery?
The sensors operate from -40 to +180 deg C and can survive +180 to +220 deg C for up to two hours. Cable routing and connector protection have their own limits and must also be checked.
 
05
Can a TQ912 or TQ902 chain support machinery protection?
Yes. Properly configured chains support shaft relative vibration and gap / position measurement, API 670 applications and selected safety-related configurations. The full chain and monitor channel must be engineered together.
