Supported Applications
The Omega iTHX-D3 Series is a web-based data acquisition system designed for monitoring and recording temperature, relative humidity, and dew point. It functions as a virtual chart recorder with an embedded web server, suitable for clean rooms, HVAC systems, laboratories, and other industrial environments.
Applications include:
- Clean room environmental monitoring
- HVAC system verification
- Laboratory process tracking
- Industrial environment surveillance via Ethernet or the Internet
Operating Conditions & Performance
The series operates within an ambient and process temperature range of -40 to 85°C (-40 to 185°F). Storage temperatures are rated from -40 to 125°C (-40 to 257°F).
Measurement performance for the industrial probe is defined by specific ranges:
- Temperature Accuracy: ±0.5°C (±1°F) for 5 to 45°C (41 to 113°F); up to ±1.5°C (±2.7°F) for -40 to 5°C and 45 to 124°C (-40 to 41°F and 113 to 255°F).
- Relative Humidity Accuracy: 2.75% RH for 10 to 90% RH; ±3% RH for 5 to 10% and 90 to 95% RH; ±4% RH for 0 to 5% and 95 to 100% RH.
- Resolution: 0.1°C (14 bit) for temperature; 0.1% (12 bit) for humidity.
- Repeatability: ±0.1°C and ±0.1% RH.
- Hysteresis: ±1% RH.
Response times are 5 to 30 seconds (tau 63%) for temperature and 8 seconds (tau 63%) for humidity. The unit weighs 113 g (0.25 lb) and features a polycarbonate case with DIN rail mount.
Configuration Options
The iTHX-D3 Series supports configurable probe lengths, specialized environmental protection caps, and optional calibration services to meet specific installation needs.
Sensor Probes & Accessories
- iTHP-5: Replacement industrial probe, 137 mm (5") length with a 3 m (10') cable.
- iTHP-2: Replacement industrial probe, 51 mm (2") length with a 0.9 m (3') cable.
- Housing Material: Probes feature 316 SS housing material; diameter is 16 mm Dia.
Environmental Protection Options
- iP-PCI-10P: Porous polyethylene probe cap for wet environments (sold in packs of 10).
- iP-SC: Porous stainless steel probe cap with 5 μm porosity, designed for dusty or pressurized (<35 psi) environments.
Power & Calibration
- Power Supply: Requires a separate switching power supply (10 to 32 Vdc). The iDRN-PS-1000 provides 95 to 240 Vac input with 24 Vdc output @ 850 mA, capable of powering up to 7 units.
- Calibration: NIST-traceable calibration certificate (CAL-3-HU) available for new units at three points: 25%, 50%, and 75% RH with temperature at 25°C (77°F). A calibrated replacement probe option (* -CAL-3-HU) is also offered.
- Calibration Kit: CT485B-CAL-KIT includes 33 and 75% RH standards.
Key Product Differences
The series offers two primary model configurations distinguished by probe insertion length and cable run, both housed in a DIN rail case:
- iTHX-D3: Includes an industrial 137 mm (5") probe on a 3 m (10') cable with stripped wire leads.
- iTHX-D3-2: Includes an industrial 51 mm (2") probe on a 0.9 m (3') cable with stripped wire leads.
