GE H201TI
Product Introduction
Protecting critical power transformers from catastrophic failure requires continuous, real-time visibility into the dielectric oil’s condition, and the (Hydran 201Ti) is engineered specifically for this purpose. Functioning as an intelligent online monitoring transmitter, this device acts as the first line of defense against incipient faults by continuously measuring the level of combustible gases dissolved in transformer oil.
Designed for demanding outdoor substation environments, the utilizes an advanced fuel cell sensor to provide a single, composite gas reading. It is highly sensitive to hydrogen (general fault gas), carbon monoxide (paper overheating), acetylene (arcing), and ethylene (oil overheating). Its simple, valve-mounted installation and lack of moving parts make it a highly reliable, maintenance-free solution for fleet-wide transformer health management.
Key Selling Points & Differentiators
- Advanced Fuel Cell Sensor: Provides a composite reading of four critical fault gases with 100% response to hydrogen, accurately covering the root causes of all major transformer faults.
- Zero-Maintenance Design: Features no moving parts, no pumps, and requires no extra piping. It installs directly onto a single oil valve using dynamic oil sampling.
- Comprehensive Alarm & Data Logging: Offers local and remote alarms (High, High-High, System Fail) and automatically records up to one year of historical data and events.
- Verified Functionality: Every undergoes rigorous sensor and communication testing before shipping, complete with a signed test report.
- Not Recommended For: Do not use this transmitter for non-oil-filled equipment or as a standard PLC I/O module. It is strictly a specialized DGA monitor for dielectric oil.
- Stock Availability: Current inventory is factory-sealed new surplus with traceable lot numbers; typically ships within 48 hours of order confirmation.
- Warranty Backed: Includes a 1-year functional warranty covering manufacturing defects and DOA conditions, with no restocking fees for verified failures.

FAQ
Yes. All units in stock have passed our functional and communication tests. We ship same-day for orders placed before 2 PM EST, so you’ll have tracking before end of day.
The features an isolated RS-485 port supporting standard Modbus RTU or proprietary Hydran protocols, making it highly compatible with most modern SCADA and DCS systems. It also provides an isolated 4-20mA analog output for simple integration.
No. The features a full-system self-test and self-diagnostic capability. It does not require field calibration, and the sensor is designed to be replaced every 2-3 years to maintain accuracy.
What if the module fails within the warranty period?
We offer a no-questions-asked replacement for any verified manufacturing defect. Ship the failed unit back with your RMA number, and we’ll send a replacement within 24 hours of receipt.
Can this monitor handle extreme outdoor weather?
Yes. The is housed in a rugged enclosure rated NEMA Type 4X and IP56, and it operates reliably in ambient temperatures ranging from -40°C to +55°C. It also includes a thermal regulating system to ensure sensor stability.
Is this a refurbished or new surplus unit?
This is New Original (New Surplus) – factory sealed, never installed, with full traceability to the original manufacturing lot. It is not refurbished, repaired, or pulled from a decommissioned system. We provide the original manufacturer’s lot code upon request for your quality records.
Quality Transparency SOP
- Incoming Verification: Source traceability confirmed via lot code; anti-counterfeit visual inspection; serial number cross-referenced with OEM records; accessories verified.
- Live Bench Test: Dedicated test bench; power-on self-check; sensor response validation; RS-485/Modbus communication handshake; 24-hour continuous load test; signed test report generated.
- Electrical Tests: Insulation resistance verified; ground continuity confirmed; 4-20mA analog output loop validation.
- Firmware Verification: Firmware version recorded; alarm thresholds and communication configuration backed up and documented.
- Final QC & Packaging: QC sign-off; anti-static seal applied; shock protection installed; QC Passed label affixed with date and inspector ID.
Test photos and video available upon request. We never claim “100% failure-free” – we provide verified, tested units with documented performance.
Technical Risk Avoidance
- Sensor Swap Mismatch: Risk: Inaccurate gas readings or system failure. Prevention: The is configured for a specific sensor. Never swap sensors between different H201Ti units. Field Note: Swapping sensors without recalibration caused false high-gas alarms. Always verify serial number matching.
- Valve Installation Torque: Risk: Oil leaks at the mounting point. Prevention: Ensure the unit is properly seated on the 1″, 1.5″, or 2″ NPT valve and sealed correctly. Field Note: Over-torquing the adapter stripped the threads, causing a slow oil leak. Follow OEM torque specs.
- Communication Wiring Errors: Risk: Loss of SCADA data. Prevention: Verify RS-485 A/B polarity and ensure proper termination if on a long daisy-chain. Field Note: Reversed A/B wires caused intermittent Modbus timeouts. Check wiring diagrams.
- Battery Depletion (Storage): Risk: Loss of real-time clock and data memory. Prevention: If storing the unit for more than 6 months before installation, disconnect the internal lithium battery. Field Note: Leaving the battery connected during long-term storage drained it in 3 years instead of 10.
- ESD Damage: Risk: Silent microprocessor failure. Prevention: Use grounded wrist strap when handling the CPU module or connecting USB/RS-485 cables. Field Note: Static discharge during configuration caused the LCD to fail. Handle with care.
