Supported Applications
The Omega OSHFV-Series (Model OS-HFV50) is a non-contact infrared temperature sensor designed for high field of view and high-temperature measurement. The series calculates surface temperature based on emitted infrared energy, converting it into an analog or digital signal while providing local visualization via a 6-digit backlight LCD display.
Operating Conditions & Performance
The OSHFV-Series operates across multiple temperature ranges depending on the selected sensor variant. The LT and LR models cover 0°C ~ 900°C (32°F to 1652°F) and 0°C ~ 1300°C (32°F to 2372°F), respectively, with a spectral response of 8 ~ 14μm. High-temperature variants H1, H2, and H3 cover ranges from 600°C ~ 1600°C (1112°F to 2912°F), 300°C ~ 1300°C (572°F to 2372°F), and 100°C ~ 600°C (212°F to 1112°F). Accuracy for LT/LR models is specified as ±1% of reading or ±1.5°C, whichever is greater; H1/H2/H3 accuracy is ±(0.5% of reading + 2°C).
Response time varies by sensor type: LT/LR models achieve a response time of 150 ms (95%), while H1, H2, and H3 variants respond in 5 ms (95%). The series features an adjustable emissivity setting from 0.100 ~ 1.000 in 0.001 increments.
The sensor housing is rated IP 64, with an ambient operating temperature of 0°C to 70°C. Storage and cable temperatures are supported from -20°C to 85°C (storage) and -20°C to 80°C (cable). Relative humidity tolerance is 10% ~ 95%, non-condensing.
Voltage, Output, and Electrical Specifications
- Power Supply: 24 VDC ± 20%, max. 100 mA current draw.
- Analog Output: 4 ~ 20mA with a maximum loop resistance of 500 Ω.
- Digital Communication: TTL / USB (requires optional communication cables).
- Cable Length: Standard 3 m, 4-cores; options available for 5 m and 10 m.
Configuration Options
The OSHFV-Series is configurable across several dimensions to meet specific optical and thermal requirements. The series supports multiple temperature ranges (LT, LR, H1, H2, H3) with corresponding spectral responses ranging from 8 ~ 14μm for lower-temperature models down to 1 μm, 1.6 μm, and 2.3 μm for high-temperature variants.
Optical Resolution (Field of View)
Different optics codes provide varying distance-to-spot ratios:
- LT Models: 60:1 (SF) or 75:1 (CF).
- LR Model: 120:1.
- H1 and H2 Models: 300:1.
- H3 Model: 140:1 (SF, CF2) or 120:1 (FF).
Mechanical Dimensions
The sensor features a rugged aluminum alloy housing with an overall length of 110 mm, diameter of Φ59.5 mm, and mounting thread M48x1.5. Weight is approximately 500g (without cable).
Signal Processing Options
The series supports signal processing modes including peak hold, valley hold, and average.
Key Product Differences
Variants within the OSHFV-Series are distinguished primarily by their temperature range codes (LT, LR, H1, H2, H3) and optical resolution. The LT/LR variants utilize a 8 ~ 14μm spectral response with slower response times (150 ms) compared to the high-temperature H-series models which operate at shorter wavelengths (e.g., 1 μm for H1) and faster response times (5 ms). Accuracy specifications also differ, with LT/LR offering a percentage-or-fixed-value tolerance structure versus the linear-plus-offset accuracy of the H-series.
Optional accessories include:
- OS-HFV50-FMB: Fixed Bracket (standard).
- OS-HFV50-AMB: Adjustable Bracket (Option).
- OS-HFV-APC: Air Purge Collar (Option).

Good device, bad documentation
The product works well, but the operator's manual contains a MAJOR error in the section on how to set up the sensor. The manual says to enter setup mode by pressing and holding both buttons. However, pressing and holding down, then pressing up resets the sensor, erasing all settings. Setup must be entered by pressing and holding up, then pressing down. This is not explained in the manual. It took 6 calls to Omega over two days to even explain to a tech support person what the error was. I hope that it will be corrected in future documentation.

Can you use this with a CNi16D44 controller? if so, how do you set up the controller for right temp reading?
You would need to scale the input of the Controller with the Analog output of the IR sensor. Once that is completed the display will show the temperature relative to what the IR device is measuring.

Am I able to receive the output of this sensor into my own application? Is there an API for it?
Thank you for your inquiry. You can either use a device that will accept an analog signal or use the optional USB Communication with the provided software.

Is it correct that the output can be adjusted between 4-20ma AND 0-5Vdc? This is reflected in the listed specs but no mentioned in the manual.
Please send your inquiry to temp@omega.com to provide assistance.

I need to sense temperature of a part which is 500 mm away. Do you have any sensor that can meet this specification?
Thank you for your inquiry. We believe the best assistance would come from speaking to us directly at 888-826-6342 ask for the Temperature Department Mon. – Fri. (HOURS 8:30AM - 5:00PM EST).

Can this wavelength range (8-14 μm) penetrate a Sapphire window? It is currently known that SiO2 window is unable to transmit.
Infrared sensors with (8-14um) Spectral Response will not see through any obstruction and will only measure the surface temperature. Omega recommends 2.5 um or less for measuring through quartz or glass and Sapphire should be OK as well.

When there are different temperatures in the FOV, will this sensor return a value based on the highest temperature, or that average of the entire FOV?
The IR sensor will take the total energy emitted by the FOV area and convert it into a temperature so it is an average.
