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 […]
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 […]
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 […]
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 […]
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 […]

Selecting A Wire
GENERAL CONSIDERATIONS Vinyl offers low Cost, good flexibility, fair electricals, a good general purpose material. Irradiated PVC offers moderate cost, heat resistance, good electrical and physical properties, excellent abrasion, cut-through and solder resistance. Teflon offers high cost, high temperature rating, excellent chemical resistance, excellent electrical properties, poor cut through resistance. Tefzel offers high cost, good […]
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, […]
Tubeskin Thermocouple In Depth
Thermometrics Corporation manufactures temperature sensors, radiant tubeskin thermocouples, petrochemical sensors and gasifer thermocouples for refining facilities around the world. Tube skin refinery thermocouples manufactured with superior metallurgy are used to measure the temperature of process such as Coker, Purge Gas Recovery, Primary Reformer, and Synthesis Converter systems. The size of the sensors are designed for […]
