#3 RTD Sensor

Thermometer
To Measure Fluid Temperature

 

Description

As it relates to differential pressure meters the RTD Sensor is used mainly in conjunction with a multivariable transmitter that compensates for temperature and pressure changes in the process being measured. The RTD sends the process temperature to the multivariable transmitter so that it can use the temperature along with the process pressure and differential pressure from the primary flow meter to calculate and output a flow signal.

Specifications

Function Purpose
Measure the process temperature.
Service Functional Limits
There are process temperature limits that have to be adhered to which vary with the RTD manufacturer.
Applications
Most gases, steam, liquids.
Common Materials
The RTD is made of various materials, but it is most commonly used with a thermowell to protect the sensor. 316 Stainless Steel is the most common material for the thermowell.
Other Available Materials:
321 Stainless Steel and Alloy 600
