Supported Applications
The Omega HX15 Series consists of high-temperature relative humidity and temperature transmitters designed for remote sensing in HVAC ducts or wall-mounted installations. The series features stainless steel probes equipped with a thin film polymer capacitor for humidity measurement and a 1000 Ω platinum RTD for temperature monitoring.
Documented configurations include:
- HX15-W: Wall-mounted RH/temp transmitter with a 79 mm (3") probe and metal wall mounting clip.
- HX15-D: Duct-mounted RH/temp transmitter with a 229 mm (9") probe, removable adjustable duct flange, o-ring, screws, and gasket.
Probes are connected to the electronics enclosure via a 1 m (40") PFA cable. The series is RoHS 2 Compliant.
Operating Conditions & Performance
The HX15 Series operates across an extended temperature range, with probe process temperatures rated from -40 to 180°C (-40 to 356°F). The electronics enclosure is designed for ambient operating conditions of -20 to 70°C (-4 to 158°F) and carries a NEMA 4X (IP66) rating.
Performance specifications are defined as follows:
- Relative Humidity Accuracy: ±2% RH, 3% to 95% @ 25°C (77°F); ±0.05% RH/°C for -40 to 150°C (-40 to 302°F).
- Temperature Accuracy: ±0.5°C (1°F), -40 to 180°C (-40 to 356°F).
- Response Time (RH): 30 s, 90% response, in 1 ms moving air.
- Response Time (Temperature): 4 s, 60% response, in 1 ms moving air.
The transmitters require a power supply of 7 to 30 Vdc and provide dual output signals: 4 to 20 mA for 0 to 100% RH and 4 to 20 mA for -40 to 180°C (-40 to 356°F).
Configuration Options
The series offers configurable mounting options tailored to specific installation geometries:
- Housing Material: ABS enclosure.
- Probe Dimensions: 16 mm diameter; overall length of 79 x 16 mm D (3 x 0.625") for wall mount and 229 x 16 mm D (9 x 0.625") for duct mount.
- Electronics Dimensions: 55 H x 80 W x 120 mm L (2.16 x 3.14 x 4.72").
- Sensor Elements: Thin polymer capacitor for RH; 1000 Ω Platinum RTD for temperature.
- Wetted Materials: Stainless steel probe, thin polymer capacitor (RH sensor), and 1000 Ω Platinum RTD (temperature sensor).
An optional PSU-93 power supply is available, providing unregulated 16 to 23 Vdc at a maximum of 300 mA.
Key Product Differences
The HX15 Series distinguishes between two primary model configurations based on probe length and mounting hardware:
- HX15-W (Wall-Mounted): Features a 79 mm (3") stem length with a metal wall mounting clip. The electronics enclosure is mounted directly to the wall.
- HX15-D (Duct-Mounted): Features a longer 229 mm (9") probe designed for insertion into ductwork, utilizing a removable and adjustable duct flange assembly with an o-ring seal.
Both variants utilize the same sensor technology and output signal architecture. Probes are not field replaceable; replacement requires exchanging the entire unit or specific accessory parts such as wall mounting clips or duct flanges where available.
