Resistance Temperature Detectors (RTDs) Used in Industry and R&D

Resistance Temperature Detectors (RTDs) Used in Industry and R&D

Process control, instrumentation, and automation applications depend on RTDs (Resistance Temperature Detectors) for various temperature sensing purposes.

Resistance temperature detectors (RTDs) use resistance to determine temperature. RTD sensors in this area are typically made of platinum 100 resistance elements (PT100) and have a resistance temperature curve (alpha or) of.00385/°C (3.851 x 10-3°C-1), although different resistance elements are widely accessible. The resistance of 100 at 0°C is what gives PT100s their name. 

Applications for RTDs are typical in industrial settings such as power plants, refineries, paper mills, food processing plants, and steel mills to monitor the temperatures of process fluids, gases, or equipment surfaces. They have also been used in industrial ovens and furnaces to control the temperature inside them.

RTDs are exceptionally accurate and repeatable at temperatures up to 500°C (900°F). Although RTDs with higher temperature ratings are accessible, their advantages over a thermocouple begin to fade at that point. 

RTDs do not necessitate the use of a properly adjusted lead wire. Three wire structures are most common in industrial applications. Choose four wire structures for the highest accuracy to avoid errors caused by lead wire resistance.

Portable Clamp-on Ultrasonic Flowmeters from AW-Lake

Portable Clamp-on Ultrasonic Flowmeters

The Portable CUTT meter from AW-Lake delivers non-invasive flow measurement in the most demanding industrial settings and applications while requiring little installation complexity and expense. 

The Portable Clamp-On Ultrasonic Flow Meter deploys to measure flow whenever needed, without requiring complex installations or disrupting the operation, as other technologies do. Transducers for the Portable CUTT fit exterior pipes ranging from 12" to 48". 

The Portable CUTT, housed in a rugged IP67 shell, is intended for use in temporary or permanent installations in any environment. These meters work with various metal and plastic pipe materials and "corrosive substances" that would harm regular inline flow meters. Consequently, the non-intrusive, clamp-on ultrasonic sensors provide superior flow measurement with an onboard Datalogger, an easy-to-use setup menu, and a long battery life with no pressure drop, making it the ideal solution for most liquid flow applications.

The Portable CUTT meter has CE approval and is CSA certified as Intrinsically Safe for use in Hazardous Area rated environments:
  • Class I, Division 2, Groups A, B, C & D
  • Class I, Division 1, Groups C and D
  • Class II, Groups E, F and G
  • Class III, Type 4
Non-Contacting Flow Measurement
Ultrasonic transducers clamp to the exterior of pipes, enabling installation without shutting down the system and causing no pressure drop.

User-Friendly Operating System
With an integrated keypad and a simple menu system, you may quickly and easily configure pipe diameter, pipe material, liquid type, and measurement units. Backup of settings, calibration, and totalizer values during power outages is standard. 

Wide Range of Applications
Compatible with various pipe materials and fluids, such as treated, raw, cooling, low-conductivity water, water/glycol mixtures, chemicals, and hydraulic, diesel, and fuel oils.

Safe in Wet Locations
IP67 (NEMA 6) rating allows for safe operation during temporary periods of submergence.

Convenient Portable Tool
Transport all you need for on-demand flow measurement in a rugged, weather-tight carrying case. Approx. shipping weight of 12 lbs (5.5 kg)

Hile Controls Provides Solutions for All Your Temperature Sensing Needs

Hile Controls Provides Solutions for All Your Temperature Sensing Needs

Temperature plays a vital role in many industrial processes. Thus precise measurement is essential. Temperatures that are not precise may have serious repercussions, such as limiting the lifespan of your equipment if overheated by a few degrees. Many processes rely on temperature monitoring to ensure fluids flow smoothly, goods stay fresh, chemical reactions are predictable, and working environments stay at the right temperature. 

Temperature sensors, indicators, and transmitters are essential for measurement in many industrial, medical, scientific, aerospace, and HVAC processes. Hile Controls, Inc., along with partner JMS Southeast, provides a complete line of high-quality standard and custom temperature sensors, including thermocouples, RTDs, and thermowells, as well as a wide selection of temperature accessories.

Sanitary Steam Traps and the Role They Play in Temperature Validated Steam-in-Place

Sanitary Steam Traps and the Role They Play in Temperature Validated Steam-in-Place

This video explains the role of the steam trap in successful temperature-validated SIP. Courtesy of Steriflow. Click here to watch video.

Steam trap design and operation play a fundamental role in successful temperature-validated SIP. If the steam trap does not open at the correct time and temperature to drain condensate, it can adversely affect heat-up time and whether the temperature hold is successful. It will negatively affect your revenue because of asset startup delays if it isn't.

SIP (Sterilize, or Steam In Place) is timed sterilization of the upstream and downstream biopharmaceutical production train using clean Steam. It is part of a 5 step sanitization routine that occurs after every production batch and follows the final rinse after CIP (Clean In Place). SIP ensures that every square inch of the production train that comes in contact with drug substance inputs, drug substance, or the final drug product is "sterilized" to ensure no microbiological activity in the system.

Clean Steam (made from USP Purified Water) is circulated through all of the process tubing during this stage and enters large vessels through spray balls embedded in the vessel ceiling.

SIP is a temperature-validated process, meaning that sterilization events are proven by measuring the event's temperature and recording the data. The minimum sterilization regimen requires the injection of clean Steam into all piping and vessels for at least 1/2 hour after reaching a minimum temperature of 250°F (121°C). If the temperature falls below 250°F (121°C) during the temperature hold period, a temperature validation fault gets logged, and SIP repeats.

Validation temperature sensors (usually RTD's) are placed at the condensate outlets of process equipment to ensure that the sterilization temperature meets the specific regimen designed for the process system. The sensing elements are usually designed with integral sheathes and Tri-Clamp™ connections and clamp directly to tubing tees, or the element inserts into a Tri-Clamp™ thermowell connected to the tee. The sensors usually are twelve to eighteen (12 - 18) inches (300 - 450mm) upstream of the clean steam trap where the condensate exits the piping or vessel.

The Perma Pure Hybrid Sample Gas Cooler

Perma Pure Hybrid Sample Gas Cooler

Sample gas coolers condition the sample gas of an analyzing system by passing it through a heat exchanger and cooling it down. Removing any moisture from the gas is a critical step in sample gas conditioning, accomplished by using suitable coolers to lower the gas temperature below the dew point, allowing water to condense. The dew point must be as stable as possible for a repeatable analysis result even when the ambient temperature varies. Sample gas coolers have broad applicability in the cement, petrochemical, steel, power generation, and process industries.

The Perma Pure Baldwin Hybrid Sample Gas Cooler combines the superior performance of Perma Pure’s Nafion™ based drying technology with the functionality of a traditional thermoelectric cooler. Powered by compressed air, this nonelectric cooler achieves dew points lower than 0˚C, helping to prevent problems associated with condensation. The patented mechanical design is ideal for locations with limited or no access to power or other areas where a nonelectric product may be desirable.
