What to Consider When Selecting Temperature Sensors

When deciding on temperature sensors for your company, there are a number of factors to keep in mind:

Performance Considerations

To receive optimal performance from your temperature transducers, be sure to:

  • Identify the range of temperatures you will be measuring with the unit
  • Determine the operating media (fluid) that will be measured
  • Determine the temperature accuracy:
    • +/- degrees
    • +/- % of reading
  • Identify the frequency response that is required:
    • Seconds in fluids to give true reading
    • Function of probe parameters
  • Determine the temperature units you will utilize:
    • Fahrenheit
    • Celsius
    • Rankine
    • Reaumure
    • Kelvin
  • Determine your over-temperature conditions:
    • Will you ever exceed the maximum temperature range?
    • To what degree?

Mechanical Considerations

  • Process connection/pressure fitting:
    • For your system, what is the maximum working pressure?
  • Material characteristics:
    • Viscosity
    • Velocity
    • Corrosiveness
    • On/off cycling
  • Physical size:
    • Size constraints
    • Location access
    • Probe length

Electrical Considerations

When purchasing temperature transducers, businesses should also consider the electrical output from the sensor and whether it is:

  • Analog
    • mV/V
    • 0-5 Vdc, 0-10 Vdc, or other
    • Bipolar voltage
    • Isolated or non-isolated voltage
    • 4-20mA current
  • Digital
    • RS485 (MODbus)
    • RS232
    • CANbus, J1939, CANopen
  • Combination
    • Analog and digital

Other electrical considerations include:

  • External zero and span potentiometers
  • Internal, DIN rail mount or in-line signal conditioning
  • Power supply specifications
  • Electrical termination:
    • Connector/cable orientation
    • Connector or integral cable
    • Wiring codes and pin-outs
    • Need for mating connectors and cable assemblies
    • Individual customer specifications

Environmental Considerations

  • Operating temperature range
  • Hazardous environment issues:
    • Intrinsically safe
    • Explosion-proof
  • EMI/RFI conditions
  • Indoor or outdoor use conditions:
    • Exposure to elements
    • Temperature extremes
    • Dirt & dust
    • Animals & insects
  • IP or NEMA rating required?
  • Submersible or subsea:
    • Depth
    • Case pressure

Special Requirement Considerations

  • Calibration requirements
  • Testing and cleaning
  • Shock and vibration resistance
  • Special approvals and certifications
  • Special labeling requirements
  • Serviceability:
    • How accessible does the unit need to be?
    • How often will the equipment be serviced?
