Sound & vibration instruments, made in India.
TIERA designs and manufactures PhonoVibe DAQ systems, TMFSS fault simulators, TVIB analysis software, and ISO 18436-2 aligned training — used by VSSC/ISRO, DRDO, NIT Trichy, and labs across India and abroad.
Designed, built, calibrated — in Thiruvananthapuram.
Three product families. One signal chain.
Capture, simulate, analyse — with instruments designed and manufactured in India.
PhonoVibe DAQ
2-, 4-, 8-, 16-channel USB DAQ. 24-bit ADC, IEPE/ICP/CCLD sensor power, TEDS support. Bundled with TVIB software.
TMFSS Fault Simulators
Reproduce 30+ machinery faults — misalignment, bearing defects, looseness, gearbox, pump cavitation — under VFD speed control.
TVIB Software
Time waveform, spectrum, FRF, octave, order tracking, modal, balancing. Free with every PhonoVibe. ~Rs 37,000 standalone value.
Four product families, one signal chain.
24-bit USB data acquisition for sound and vibration. Plug-and-play. Made in India.
Five models — 2, 4, 8, 16-channel, plus the Eco X bundle with built-in shaker. All 24-bit, all USB plug-and-play, all bundled with TVIB software. Compatible with IEPE/ICP/CCLD sensors and TEDS.
Experience · Train · Innovate — 30+ machinery faults reproduced on a benchtop simulator.
Portable simulator for repeatable rotating-machinery faults. Three sizes — Macro for research and full-industry training, Mini for academic and entry-level, Micro for classroom. Add-on kits expand the fault library. Make in India.
The modular analysis toolbox that runs every TIERA DAQ — and many third-party ones.
TSAP201 base module free with every PhonoVibe. Add modules — vibration meter, sound level meter, FRF, balancing, order tracking — only when you need them.
Hands-on benches for vibration analyst certification courses.
Compact, classroom-friendly hardware bundles that pair with TCAT Cat I / Cat II syllabi — bearing-fault rigs, balancing benches, and structural-modal demonstrators. Designed to fit a 6-ft table.
Capture. Analyse. Decide.
- 01
Capture
PhonoVibe DAQ samples up to 128 kHz at 24-bit through IEPE sensors with TEDS — plug-and-play over USB on Windows 10/11.
- 02
Analyse
TVIB TSAP 201 runs spectrum, FRF, octave measurements, order tracking and modal — the standard diagnostic toolbox vibration analysts already use.
- 03
Decide
Export trends, share reports, and act before failure. Optional TCAT training — aligned with ISO 18436-2 — turns your team into qualified analysts.
PhonoVibe D — 2-channel DAQ
The entry into 24-bit sound & vibration data acquisition.
Ships with TVIB TSAP 201, connectors and cables, factory calibration certificate.

Engineered in India. Priced for Indian industry.
Make in India
Designed, manufactured, and calibrated at our Thiruvananthapuram facility. Not a reseller of imported gear.
Affordable by design
Price advantage versus imported brands is a deliberate engineering and supply-chain choice — not a quality compromise.
Bundled value
Every PhonoVibe ships with TVIB software (~Rs 37,000 value), connectors and cables, and a 2-year warranty.
Training-aligned
TCAT courses are aligned with ISO 18436-2 Cat I and Cat II syllabus — same standard your reliability team is already certified to.
Things customers ask, with straight answers.

Is TIERA ISO 9001 certified? +
No. We don't currently hold ISO 9001 and we don't claim it. Our TCAT training courses are aligned with the ISO 18436-2 vibration analyst syllabus — that's a different standard, about analyst certification, not company certification.
Will TVIB software work with my non-TIERA DAQ? +
TVIB TSAP 201 is officially supported on PhonoVibe DAQ systems (D, Q, O, HD, Eco X). For third-party DAQs, talk to support@tieraonline.in about compatibility — case by case.
What's included with a PhonoVibe DAQ? +
Every PhonoVibe ships with TVIB TSAP 201 software (~Rs 37,000 standalone value), connectors and cables, a factory calibration certificate valid for one year, and a 2-year warranty extendable to 3.
How many faults can TMFSS Macro simulate? +
30+ in the base kit — misalignment, unbalance, bearing faults (outer/inner/cage), foundation looseness, resonance, coupling studies, mechanical rub, cocked bearing, bent shaft, gearbox, electrical motor faults, pump cavitation, accelerated bearing wear, and more. Expandable with add-on kits.
What does a TCAT certification cost? +
TCAT Cat I (ISO 18436-2 aligned): Rs 25,000. Cat II: Rs 85,000. Bundle (Cat I + Cat II): Rs 95,000. Certification exams are separate — Cat I Rs 5,900, Cat II Rs 15,000. All available online at learn.tieraonline.in plus optional on-site sessions.
Do you sell internationally? +
Yes. International prices are in USD, EXW Thiruvananthapuram. We have distribution partners — USENS in Korea, and SSPL in India. For other regions, write to ceo@tieraonline.in directly.
What's the payment route for academic and PSU buyers? +
Academic buyers get a 10–15% discount on hardware (talk to us for the exact figure on your kit). GeM rate contracts apply for eligible defence/PSU procurement. GST is 18% IGST or 9%+9% within Kerala — invoiced separately from product price.
