IN-USBH USB in-line field calibratable signal conditioner

Supported Applications

The Omega IN-USBH is a USB In-Line Field Calibratable Signal Conditioner designed for mV pressure or load transducers. It enables the direct connection of these sensors to a computer, utilizing free PC software to function as a virtual meter, chart recorder, and data logger on laptops or Windows® tablets with USB connections.

The device supports applications requiring dynamic measurement or slow-moving process monitoring by providing adjustable sampling rates up to 1000 Hz. Logged data can be exported in spreadsheet format for later viewing and analysis.

Operating Conditions & Performance

The IN-USBH operates within an ambient temperature range of -40 to 80°C (-40 to 176°F). It provides a resolution of up to 5.5 significant figures with a 24-bit A/D conversion and maintains a linearity error of 0.001% FSO. The thermal error is specified as 0.001% FSO/°C.

Performance specifications include a bandwidth typical of up to 1000 updates per second (±3%) and minimum isolation of 2 MΩ @ 50 Vdc from case to output terminations. The unit provides regulated excitation at 4.1 Vdc* directly to the transducer, eliminating the need for an external power supply.

Transducer requirements are defined as follows:

• Bridge Sensitivity: 1 to 400 mV/V
• Bridge Resistance: 350Ω to 15,000Ω

Configuration Options

The series features a compact in-line design with an overall length of 101 (4.00) mm and a diameter of ø22 (0.88) mm. The housing is constructed from a 316L Stainless Steel Case, weighing approximately 200 g (7.1 oz) including the USB cable.

Connectivity options include:

• Transducer Side Connection: PTIH-10-6P 6-pin twist-lock male connector
• Mating Connector: PT06F10-6S (sold separately)
• USB Side Connection: 2 m (6') USB 2.0 cable

The IN-USBH is field-calibratable using two-point or datasheet parameters via the included software. A stainless steel mounting bracket is included with the unit.

Cable Assembly Options

Pre-made interconnecting cable assemblies (CA*INUSBH) are available to connect specific transducers to the IN-USBH. These cables feature different insulation types and wiring codes tailored to various Omega sensor families:

• PVC Insulation (-30 to 80°C / -22 to 176°F): Available for load cells (LC series) and pressure transducers (PX, LCHD).
• FEP Insulation (-55 to 125°C / -67 to 257°F): Offered for high-temperature applications with specific PX series models.
• Cable Lengths: Standard assemblies are listed at 0.15 m (implied by part number suffix), though lengths longer than 15' may be available upon contacting sales.

Key Product Differences

The primary model, IN-USBH, is the field-calibratable USB in-line signal conditioner. The series supports various configurations through optional pre-made cable assemblies (CA*INUSBH) that match specific transducer wiring codes and connector types.

Differences between available cables are defined by:

• Insulation Material: PVC or FEP, determining the temperature rating of the assembly.
• Wiring Code: Codes such as 2A, 3, 4/4A, 5, 6, and 8 correspond to specific pinout arrangements for different transducer families (e.g., LC111, PX35, LCHD).
• Connector Types: Assemblies may terminate in PT06F10-6S or MS3106E-14S-6S connectors on the transducer side to match specific sensor interfaces.
