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.
Four 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, NDT RAM, order tracking — only when you need them. Perpetual licence, 14-day trial available.
ISO 18436-2 exam preparation without a test rig.
To-Learn Vibe is a PC-based vibration simulation software that reproduces rotating machinery faults — unbalance, misalignment, bearing defects, looseness — with realistic spectra the trainee must diagnose. Annual subscriptions at three tiers suit individual analysts, training centres, and corporate programmes.
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.
Traceable calibration for IEPE accelerometers, on your bench.
The T-Calibro is a back-to-back vibration calibrator that verifies the sensitivity of IEPE accelerometers against an NPTEL-traceable reference. A dedicated software workflow automates calibration records and generates certificates ready for audit.
Clean constant-current excitation for every IEPE sensor in your setup.
The TSP series are bench-top and portable constant-current power sources for ICP®/IEPE sensors. Available in 1-channel (TSP 02) and 4-channel (TSP 04) configurations, they decouple sensor bias from signal output and deliver noise-floor performance suitable for precision vibration and acoustic measurements.
Controlled excitation signals for shaker-based structural testing.
TWGM 206 is a software-based waveform generator module that drives TIERA T-Xcite series shakers and amplifiers. It generates pink noise, white noise, sine sweeps, and burst signals required for frequency response function measurements, modal analysis, and NVH evaluation.
From sensor tip to DAQ input — every link in the measurement chain.
TIERA offers accelerometers, condenser microphones, IEPE cables, mounting blocks, and adhesive pads selected to work directly with PhonoVibe DAQ systems and third-party instruments. All accessories carry individual datasheets available in the public datasheets repository.
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.

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.
Don't see your question? Email sales@tieraonline.in.
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.
