Infrared Temperature Sensors
Omega Engineering, Inc.
STAMFORD, Conn., Feb. 24, 2013 — The OS-Mini series infrared pyrometers from Omega Engineering Inc. have a sensing head measuring 18 × 45 mm, enabling mounting in tight spaces. A high ambient version withstands temperatures of up to 180 °C without water or air cooling.
Manufactured from 316 stainless steel and sealed to IP65, the mini sensing head is suitable for food and pharmaceutical applications. A wide selection of optics enables focusing on small or large targets at short or long distances. The low-noise interconnecting cable is resistant to interference from movement, making the sensing head suitable for mounting on robot arms. The cable can be supplied in lengths from 1 to 30 m.
The backlit touch-screen interface provides a large, bright display of the measured temperature in digital format, and a graph view shows the history of the measured temperature. It also enables full configuration of the sensor, including temperature range setting from −20 to 1000 °C, adjustable filtering, peak or valley hold processing, emissivity setting and reflected energy compensation. In alarm conditions, the display changes color to provide an immediate alarm indication.
Alarm modes and levels can be configured via the touch screen. When fitted with a MicroSD card, the Omega mini also functions as a data logger to record process temperatures for quality assurance and traceability. The user can select the sample rate and the number of samples to be taken and schedule the data logging to start at a certain time. With a 2-GB card, the user can store 28.4 million time- and date-stamped readings. Output options include 4 to 20 mA, RS-485 Modbus and alarm relays, which are rated 24 VDC, so there is no need for a separate trip amplifier. Other options include mounting brackets, an air purge collar, a protective lens cover and a laser sighting tool.
