Product Introduction (Structure A: Environmental hook)
FOXBORO 69TA-2RH is a rugged piezoelectric accelerometer used for bearing housing and casing vibration measurement on steam turbines, gas turbines, centrifugal compressors and large process pumps in power generation, oil & gas and petrochemical facilities. It is built to withstand high mechanical shock, continuous vibration, EMI interference and wide temperature swings that degrade ordinary vibration transducers. This sensor converts casing mechanical vibration acceleration into proportional analog electrical signals for FOXBORO machinery health and protection systems. The suffix 2RH designates side-exit connector construction, ideal for tight mounting spaces on bearing pedestals. Hermetically sealed stainless steel housing shields the internal piezo crystal from moisture, dust and corrosive industrial contaminants. Sensor linearity, shock resistance and API670 compliance are key audit checkpoints during rotating machinery safety assessments.

Global Compliance & Industry Certifications
- CE Mark
- UL/cUL Listed
- API 670 Rotating Machinery Protection Standard
- ISA-S71.04 G3 environmental contaminant rating
- RoHS compliant for applicable production batches
UL certification validates insulation and environmental performance for continuous long-term installation on turbine/compressor bearing housings. Serial-number specific certificates should be validated per individual unit.
Long-Term Storage & Asset Preservation Guide
Store the FOXBORO 69TA-2RH accelerometer sealed inside original ESD shielding bag and reinforced shipping crate in a dry, temperature-stable warehouse. Electrostatic discharge can damage the delicate piezoelectric crystal, resulting in sensitivity drift, weak signal output or complete loss of vibration measurement after field installation. Inspect spare sensors every 24 months. For units stored more than three years, perform bench sensitivity calibration test before commissioning; aging of internal piezo components may reduce measurement precision. Do not stack heavy hardware on the sensor housing. Mechanical impact may crack the crystal element and lead to intermittent or permanent vibration measurement failure.
Physical Installation Prerequisites
Prepare clean, flat mounting surface on bearing housing with proper stud mounting. Uneven surfaces will introduce measurement distortion and signal noise. Mount 69TA-2RH using the specified mounting stud. Separate sensor low-noise cable from high-voltage power wiring to minimize EMI noise. Use matched FOXBORO low-noise extension cable. Bond machinery chassis to protective earth. Connect cable to FOXBORO monitoring card and complete signal loop test and calibration after physical sensor installation.
Buyer’s FAQ
Q: What HS tariff code applies to FOXBORO 69TA-2RH for cross-border shipments? A: Primary HS classification falls under 853710 for industrial vibration transducer assemblies. Confirm classification with your customs broker before export filings, as rulings depend on supporting technical documentation.
Q: What country of origin is marked on FOXBORO 69TA-2RH? A: Country of Origin is United States. This marking appears on the sensor nameplate and must be reproduced on commercial invoices for cross-border compliance audits.
Q: What does suffix 2RH stand for? A: 2RH = side-exit cable connector variant; other suffixes define top exit or different connector types, variants are not physically interchangeable.
Q: Should I purchase all-risk shipping insurance for this spare FOXBORO accelerometer? A: Yes. Transit shock can damage the fragile piezoelectric crystal. Intermittent vibration signal faults may only manifest after field mounting and wiring connection. All-risk insurance covers full replacement value for transit handling defects.
