Supported Applications
The Omega RH-USB Series is a USB Temperature & Humidity Sensor with Datalogging Software designed for direct connection to a PC. The series includes the RH-USB model, which measures relative humidity and temperature. According to the product overview, these devices are intended to turn a PC into a data logger using free software.
Explicit usage restrictions state that this device is not designed for use in medical or nuclear applications. Additionally, do not operate this device in flammable or explosive environments.
Operating Conditions & Performance
The RH-USB sensor features a stainless steel housing and connects via USB to provide output signals directly to the host computer. The overall length of the RH-USB unit is 131 mm (5.18 in).
Detailed technical specifications such as measurement ranges, accuracy values, resolution, response time, or operating temperature limits are not provided for the RH-USB model beyond general descriptions in the source documentation.
Configuration Options
The series supports a direct USB electrical connection. The housing material for the RH-USB is stainless steel. While other models within the broader Omega USB family (such as TJ-USB, UTC-USB, PX409-USB, and IR-USB) offer different measurement types including thermocouple temperature, universal thermocouple conversion, pressure transduction, and infrared sensing, these capabilities are specific to their respective model numbers.
Accessories listed for the broader USB family include:
- Laser Sighting Accessory (OS100-LS)
- Mounting Bracket (OS100-MB)
- Water Cooling Jacket (OS100-WC)
- Air Purge Collar (OS100-AP)
The series complies with worldwide safety and EMI/EMC regulations. Certification to European New Approach Directives is being pursued.
Key Product Differences
The Omega USB Series encompasses multiple distinct measurement technologies under a single family manual, though the RH-USB-Series specifically addresses temperature and relative humidity sensing via USB. Other models in the broader product overview include:
- TJ-USB: Type-K Thermocouple (overall length 914.4 mm / 36.0 in; stem lengths of 457.18 mm / 18.0 in or 609.6 mm / 24.0 in)
- UTC-USB: Universal Thermocouple Connector/Converter
- PX409-USB: Pressure Transducer (wetted material: 316L stainless steel)
- IR-USB: Infrared Temperature Sensor
The RH-USB is distinguished by its specific measurement of relative humidity and temperature, whereas the other models serve different sensing functions. Dimensions for UTC-USB, PX409-USB, and IR-USB are not specified in the provided documentation.
