Internal leads of the #compensating #cable are made of materials which correspond to the #thermoelectric properties of the original T/C.

A #transducer is an #electronic device that converts #energy from one form to another. Examples include #thermometers, and pressure #sensors

Thermometrics Corp. (@thermometrics) 's Twitter Profile Photo

The most common #flange #standards are ASA/ANSI (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean).

Using lead #wires to place any distance between a two wire #RTD and a receiving device will further compromise its #accuracy. #tempsensors

When most metals are placed into a coil, they will change in resistance as their #temperature changes. This is particularly true of platinum

For an #RTD sensor, it's the wires which connect to the #sensing element & the #wire #insulation which generally limits the max #temperature

Slip-on #flanges are #designed to slide over the outside diameter of the #pipe. These #flanges are attached to the pipe by fillet #welding

Ohm’s #Law expresses the #correlation between #electric #current (I), #voltage (V), and #resistance (R) in a #conductor. V = I x R

There are several tungsten-rhenium alloy #thermocouples in use, but the only one #standardized is tungsten 5% rhenium/tungsten 20% rhenium

For #RTD #sensors TCR is normally defined as the average #resistance change per °C over the range 0 to 100°C, divided by R °C: 0

Most popular temp #resistors are based on #platinum & nickel. First #sensor made was the platinum sensor with the resistance of 100Ω #PT100

With an #RTD #Probe a #transmitter is generally recommended when lead #wire length approaches 100 feet, or if a 4 – 20 mA output is desired.
