Non-contact infrared temperature sensor, transmitter
OS137 Series from Omega offers three measuring ranges, many features in a small package.
Omega’s new compact high-performance, industrial infrared sensor and transmitter combination, model OS137, provides a variety of features and options packaged into a small stainless steel housing. The standard features are adjustable emissivity, 10 to 1 optical field of view, adjustable alarm set point and voltage output to drive external relays, and six pre-selected analog outputs that can easily interface with all meters, controllers, dataloggers, recorders, computer boards, and PLCs. The unit comes with two hex nuts, 1.8 m (6 ft.) shielded cable for power and output connections, and complete operator’s manual.
Three temperature ranges available:
• OS137-1: 0 to 100 °C (32 to 212 °F);
• OS137-2: -18 to 260 °C (0 to 500 °F); and
• OS137-3: -18 to 538 °C (0 to 1,000 °F).
Outputs include: 4-20 mA, 0-5 Vdc, 0-10 Vdc, 10 mV/deg, and Type K thermocouple. Accuracy is ±1.5% Rdg or 3.5 °F (2 °C), whichever is greater with repeatability of ±1% Rdg or 2 °F (1 °C).
