Infrared Temperature Sensor
Features:
✅ Intrinsically safe for use in Hazardous Areas: Zone 0, 1, 2 (Gas); Zone 20, 21, 22 (Dust) – with suitable isolator
✅ Non-contact infrared measurement with 4–20 mA two-wire output
✅ Temperature ranges up to –20 °C to 1000 °C (depending on FOV and variant)
✅ Adjustable emissivity from 0.20 to 1.00 (preset 0.95), configurable via USB adaptor
✅ Fast t₉₀ response time of 240 ms and high readout stability
✅ Compact 316 stainless steel housing, IP65 sealed, suitable for offshore environments
The OSAT Series from Omega Engineering is a compact, rugged, and intrinsically safe infrared temperature sensor designed for hazardous industrial environments. It offers non-contact temperature monitoring with high accuracy and fast response times, while ensuring full compliance with ATEX and IECEx standards.
The OSAT is an infrared pyrometer that is inherently safe. It has a direct 4–20 mA output and can measure the temperature of surfaces in dangerous regions without coming into touch with them. It has ATEX, IECEx, and TIIS certifications. The OSAT is a low-cost, tiny, and portable solution for measuring temperature in dangerous areas. In contrast to explosion-proof pyrometers, which usually have large, costly housings, it employs intrinsic safety as its protection mechanism.
Non-Contact Temperature Measurement with Precision and Speed
Infrared temperature sensors offer accurate, real-time temperature readings without direct contact, making them ideal for applications where conventional sensors cannot be used.
Key Features:
Non-Contact Measurement
Detect surface temperature from a distance using infrared radiation – ideal for moving objects or surfaces that are hard to reach.High Accuracy & Fast Response Time
Quick and precise measurements with response times as fast as 50 ms.Wide Temperature Range
Capable of measuring extreme temperatures, typically from -40°C to +1000°C (model-dependent).Adjustable Emissivity
Supports different surface types with configurable emissivity for better accuracy.Multiple Output Options
Available with analog (4–20 mA, 0–10 V) or digital (RS232, RS485, Modbus) outputs for seamless system integration.Rugged and Compact Design
Built for harsh industrial environments, with IP65/IP67-rated housings.Easy Installation
Compact size, mounting brackets, and optional laser sighting simplify alignment and setup.
