Bayond RTD: In-Depth

Bayonet RTD In Depth

Bayonet RTD Bayonet RTDs, Thermistors and Thermocouple temperature sensors are commonly used in extruder and plastic processing industries. These sensors provide accurate temperature control for the best plasticizing combination of plastic material, mold and design. Bayonet RTD temperature sensors are available in 6 configurations; Adjustable Immersion Bayonet on Flex Armor Bayonet on Flex Armor with transition Bayonet on Spring Fixed Immersion Bayonet Straight Bayonet 45° Degree Bend Bayonet 90° Degree Bend The 6 standard design's are available to meet the requirements for space conservation...

RTD Standards: Accuracy & Tolerance

RTD Sensor Accuracy and Tolerance Standards

RTD Sensor Accuracy and Tolerance Standards   The industry standard for platinum RTD's according to IEC-751 is + /- 0.12% (of resistance) at 0°C, commonly referred to as Class B accuracy. This will provide an accuracy of + /- 0.3°C at 0°C, which is quite good if you compare it to the + /- 2.2°C of a standard Type J or K thermocouple. But as the temperature increases, so does the permissible deviation due to the variations possible in the TC....

Story of Temperature

The Story of Temperature

What is Temperature? In a qualitative manner, we can describe the temperature of an object as that which determines the sensation of warmth or coldness felt from contact with it. It is easy to demonstrate that when two objects of the same material are placed together (physicists say when they are put in thermal contact), the object with the higher temperature cools while the cooler object becomes warmer until a point is reached after which no more change occurs, and to...

Food Processing Temperature Sensor

A bimetal bayonet style thermometer with a dial face scale with a range of -18 to 105°C (0 to 220°F) may be used for certain applications in food temperature measurement. The scale must be in 1°C increments. The dial face should be a minimum of about 1 inch in diameter and is usually available in larger sizes. The stem length should be a minimum of 127 mm and may need to be much longer to measure thicker foods. Specific measurement...

RTD vs Thermocouple

RTD vs. Thermocouple

Selecting The Right Sensor: Imagine that you are an Instrumentation Engineer. You are looking at the prints for a new plant, and you see the many locations marked out for temperature transducers. You ask yourself; What has been specified to fill each space? RTD for their high accuracy and linearity? Or thermocouples because of their lower cost and familiarity? Has anything been specified to fill these spaces? The selection of what type of temperature tranducer to be used affects many other...

EGT Sensors

Exhaust Gas Temperature (EGT) Sensors & Pyros

Measure Exhast Gas Temperature (EGT) Exhaust gas temperature is a measure of heat in the cylinder during combustion, and is most commonly measured close to the head. Since all metals melt, deform, or undergo transformation under excessive temperatures for that particular metal, it is easy to have too high of EGT and cause damage to engine/turbo components. Thus a tuner must measure the EGTs and keep them in check or suffer the consequences. High EGTs also contribute to knock. You...
