Temperature sensor: Accurate, low-cost, general-purpose unit
Inexpensive thermistor design suited for light- and moderate-duty applications.
When a situation calls for a large number of temperature sensors for a simple, moderate-duty application, a low-cost but reliable technology can fill the bill on a budget.
Spectrum Sensors and Controls has introduced a general-purpose temperature sensor covering a range from 0 °C to 70 °C, that reportedly combines excellent thermal response, high accuracy, and rugged construction in a low cost package. This sensor assembly is easy to use to monitor air temperatures or it can be installed in a thermowell for liquid sensing, making it ideal for standard controllers or data loggers.
This new sensor features sturdy construction with a fully potted metal housing. It encloses a fast response thermistor element and a plastic molded shell that thermally isolates the assembly from the environment and also adds a degree of strain relief. This sensor is available in a variety of RvT curves and thermistor resistance values ranging from 2.2 k? to 10 k?, providing accuracy of
Spectrum Control designs, manufactures, and markets a broad line of EMI/RFI filters and power components, power management systems, microwave components, and position and temperature sensors and controls.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
