Resistence Elements

Resistance Elements

Introduction Resistance elements come in many types conforming to different standards, capable of different temperature ranges, with various sizes and accuracies available. But they all function in the same manner: each has a pre-specified resistance value at a known temperature which changes in a predictable fashion. In this way, by measuring the resistance of the element, the temperature of the element can be determined from tables, calculations or instrumentation. These resistance elements are the heart of the RTD (Resistance Temperature...

Temperature Transmitters

Temperature Transmitters General Overview Analog (4 - 20 mA) transmitters provide a number of benefits for use in industrial sensing.The nature of current (versus voltage) loops is to maintain the proper current, even if there is significant electrical resistance in the line, up to its maximum voltage capability.For this reason, current-based control loops can be used over much greater distances (measured in miles versus feet). The 4 mA "live zero" provides a method to determine equipment failure, should the signal drop...

Intro to Thermowells

Introduction to Thermowells Materials—The Longevity Factor- In general, the thermowell material to be chosen for an installation is governed mainly by the corrosion conditions the well will face. The high polish given to all stainless and Monel wells provides maximum corrosion resistance. Occasionally, the primary consideration is one of strength rather than corrosion resistance. For example, a stainless steel well may be required for high pressure water service instead of a brass well which would be satisfactory from a corrosion standpoint....

3A Sanitary Temperature Measurement - Thermometrics Corp

Why is 3A Sanitary Temperature Measurement Important?

The following systems are dependent upon accurate temperature measurement: Pasteurization Systems include high temperature short time (HTST) at 105 degree's celsius and higher heat shorter time (HHST) at 146 degree's celsius requirements. Boiler Feed Water Systems include temperature measurement to reduce water hardness and to prevent corrosion and scale in boilers and or to facilitate sludge removal for proper boiler care and operation. Sanitation Systems include temperature, time and the conventration of specific detergent solutions and bactericides. Cleaning and sanitizing procedures routinely...

Intro to Pipe Flanges

Pipe flanges insure pipe and tube sections are sealed tight. Pipe flanges are American National Standards Institute (ANSI) rated for pressure y, corrosion resistance and maximum strength. Whenever installing flanges, either cast flanges (part of pipes or tubes) or ring flanges (slid onto to pipe or tube collars), always make sure the line's pressure will carry and what will contain. Stainless steel will work well with water or steam but can wear away quickly if subjected to caustic slurry or...

Weld Pad Temperature Sensors In Depth - Thermometrics Corp

Weld Pad Temperature Sensors In Depth

Thermometrics manufactures a full line of standard and custom weld pad RTD's. The weld pad (tube skin) termination allows a temperature sensor to be welded directly onto piping or other metal surfaces to sense the surface temperature. Weld pads are most commonly used in fired heater tubes, refinery heater tubes, boilers and furnaces in refineries, and industrial boilers. However, they can be used in virtually any application requiring surface temperature measurement. Weld Pad (Tube Skin) RTDs come in 4...
