Item# (PN): OS36SM Shipping and Payment
The subminiature OS36SM Infrared Sensor combines thermocouple outputs with the advantages of non-contact temperature measurement. The OS36SM produces a thermocouple output signal (type K) that can be used with many of the Omega controllers. The thermocouple output also removes the need for an external power source because of it's self-powering feature. The OS36SM can be outfitted with an air purge jacket to increase ambient temperature rating to 175°C.
The OS36SM has a calibrated sensing range of -18 to 250°C and operating temperature range of -18 to 85°C. These sensors can achieve higher ambient temperature ratings with the OS36SM-APJ up to 175°C with air cooling. The housing is hermetically sealed and NEMA 4, IP67 rated.
The OS36SM series is designed for applications such as rough steel plates, unpolished stainless steel, brick, asbestos, paints, quartz, water, wood and more. This sensor is designed for space limiting applications that require non-contact temperature measurment.
You can order the sensor, including the installation of connector. Put the required low noise connector in the basket together with the sensor. If needed, order the required connector separately, see "Accessories" below.

How is Temperature Measured?
Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic. Six types with which the engineer is likely to come into contact are: thermocouples, resistive temperature devices (RTDs Pt100 and thermistors), infrared radiators, bimetallic devices, liquid expansion devices, and change-of-state devices.

What are Infrared Temperature Sensors?
An infrared thermometer is a sensor that consists of a lens to focus the infrared (IR) energy on to a detector, which converts the energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation. This configuration facilitates temperature measurement from a distance without contact with the object to be measured (non-contact temperature measurement).
As such, the infrared thermometer is useful for measuring temperature under circumstances where thermocouples or other probe type sensors cannot be used or do not produce accurate data for a variety of reasons...

What Are Common Applications for Thermocouples?
Thermocouples are the most widely used temperature sensors on the planet due to their combination of wide temperature capabilities, ruggedness, and low cost. Thermocouples are used in applications that range from home appliances to industrial processes, to electric power generation, to furnace monitoring and control, to food and beverage processing, to automotive sensors, to aircraft engines, to rockets, satellites and spacecraft.
When it comes to high temperatures, small size, fast response, high vibration or shock, most times you will find thermocouples providing the temperature measurements.

Common Techniques to Calibrate Thermocouples
Temperature measurement is possible through several means. We commonly use thermometers for measuring temperature. However, for precision measurements, where even a small spike in temperature requires to be recorded, we use advanced forms of measurement devices like thermocouples. Thermocouples are measurement devices that can read very slight temperature changes. Hence, they are widely used in applications where accuracy is of utmost importance.
However, like any measurement device, the efficiency of thermocouples will deteriorate overtime under constant use. At this point, the thermocouple needs recalibration...
