  • Measuring Molasses with a WORM

    A rigid sensor couldn't measure temperature accurately in a conventional thermowell, but a custom thermowell and a WORM RTD flexible sensor measure the molasses perfectly.

  • Designing with Thermocouples: Get the Most from Your Measurements

    More than 60 percent of all industrial temperature measurement applications in the U.S. use thermocouples. Despite their widespread use, there are many misconceptions about thermocouples. This paper will discuss some of the basic technical issues that engineers need to consider when applying thermocouples.

  • New Differential Pressure Sensor Incorporates LVDT Technology to Create More Environmentally-Resistant, Dependable and Economical Pressure Sensing Solution

    Differential pressure (dP) sensors with electronic signal processing are increasing being used to monitor flow, filter condition and level. Since these devices offer linear and accurate output, they are also replacing the differential pressure switch that only support on-off condition and useless for closed loop control system. These dPs are often configured with expensive valves and fluid filled remote seals for added protection against corrosive media, radiation and/or extreme media temperature ranges when operating in demanding environments. In cold ambient environment specially operating in temperatures below -4 deg F (-20 deg C), the sensor need to be heated either by trace heater or within a heated enclosure to maintain the operation of the dP sensor. In addition to being expensive, these valves and seals tend to be bulky and require time to install and maintain. In many critical applications such as food and pharmaceuticals, filled fluids are a serious concern due to process contamination. In gaseous systems such as hydrogen and oxygen and semiconductor applications, fluid filled sensors are being banned since the leakage of fluid into the process could lead to an explosion and serious safety issues.

    A new series of LVDT (linear variable differential transformer) based oil-less dP sensor with dual channel ASIC (applications specific integrated circuit) have been developed that can operate in a wide range of corrosive materials, radiation and temperature without any oil filling and bulky sealing systems. By encapsulating LVDT proven technology with digital compensation, the pressure sensors combine the benefits of friction-free operation, environmental robustness and unlimited mechanical life. By selecting the diaphragm thickness and material properties, Table 1 show the dP ranges that can be produced using the LVDT technology.

  • AMS2750D Temperature Uniformity Surveys Using TEMPpoint

    AMS2750D Temperature Uniformity Surveys using TEMPpoint.

    Industrial process furnaces and ovens require uniform temperature and heating; This is critical to repeatable product performance from batch to batch. These furnaces require periodic inspection for temperature uniformity.

    Electronic and Mechanical Calibration Services, Millbury Massachusetts characterizes temperature uniformity in industrial furnaces and ovens for their customers. This is accomplished by measuring temperature in several locations throughout the furnace and monitoring temperature with thermocouples over time according to AMS2750D specifications.

    The customer previously used chart recorders which require constant monitoring while the survey is running. Surveys can run anywhere from 35 minutes to several hours long depending on the industry specified requirements. With the TEMPpoint solution the operator can set it up and let it run unattended, freeing them up to multitask their time and work more efficiently. The shipping TEMPpoint application required very little modification using Measure Foundry and now fulfills customer's requirements.

  • Avoid Pitfalls in Precision Temperature Measurement

    Everyone is familiar with the concept of temperature in an everyday sense because our bodies feel and are sensitive to any perceptible change. But for more exacting needs as found in many scientific, industrial, and commercial uses, the temperature of a process must be measured and controlled definitively. Even changes of a fraction of a degree Celsius can be wasteful or even catastrophic in many situations.

    For example, some biotech processes require elevated temperatures for reactions to occur and added reagents require exactly the right temperature for proper catalytic action. New alloys of metal and composites, such as those on the new Boeing 787 Dreamliner, are formed with high temperature methods at exacting degree points to create the necessary properties of strength, endurance, and reliability. Certain medical supplies and pharmaceuticals must be stored at exactly the desired temperature for transport and inventory to protect against deterioration and ensure effectiveness.

    These new applications have driven the hunt for more exacting temperature measurement and control solutions that are easy to implement and use by both novice users and experienced engineers alike. This is a challenging task. However, new equipment and standards, such as LXI (LAN Extensions for Instrumentation) offer a methodology to perform these exacting measurements in test and control applications.

    Many LXI devices are available on the market today. But, what do you need to know to select the best temperature measurement solution for your test and control application? This paper describes the common pitfalls of precision temperature measurement and what you need to consider before selecting a temperature measurement solution.

  • Wireless Devices Deliver Great Benefits for Temperature Monitoring

    Temperature is certainly among the most commonly measured parameters in industry, science, and academia. Recently, the growth of wireless instrumentation technology, along with some clever innovations, has provided new ways to apply temperature measurement sensors combined with personal computers to collect, tabulate, and analyze the data obtained. For complex, multi-sensor applications, wireless devices provide a means to eliminate the nuisance of running multiple leads over long distances through harnesses or conduit to a control room, instrument panel, or equipment rack, while keeping track of which leads are which. For simpler one or two sensor applications, it means installing the wireless sensor, setting up the receiver, and being done. There are now so many wireless transmitting and receiving devices available for temperature measurement that nearly any application can benefit from their use. In any case, it is certainly worth a closer look. As a bonus, most of the devices discussed below also work with humidity and barometric pressure sensors.

  • The Fundamentals of Refractory Inspection with Infrared Thermography

    Thermography has been used to inspect the condition of refractory lined vessels and piping for many years now. It is a proven and accepted method for locating damaged and missing refractory material. Most companies however, do not fully understand the full benefits of performing refractory surveys. They mainly use thermography only before a plant turnaround to determine the extent of refractory damage in order to estimate the materials and labor needed for the repairs. This paper discusses the fundamentals of refractory inspection and how Thermal Diagnostics Limited has been using Infrared thermography in Trinidad and Tobago as an effective means of predicting areas of future refractory problems in addition to pre-turnaround surveys.
