Temperature Transducers and Temperature Transmitters

Temperature Transducers and Temperature Transmitters


Temperature transducers and temperature transmitters are designed to measure and monitor a wide range of temperatures in a variety of industries and applications, including subsea, space, factory automation, medical, agriculture and other industries. Our selection of thermostat, thermistor, RTD and thermocouple sensors provide accurate and repeatable measurements, with ranges from -320°F to +750°F, in a variety of sensor housings and probe lengths. The dual output option provides simultaneous pressure and temperature sensing within the same standard probe housing.

Non-amplified Temperature Transducers

Non-amplified Temperature Transducers

Non-amplified temperature transducers are designed to measure both dynamic and static temperatures. Additional features include all-welded stainless steel, compact size, low sensitivity to shock and vibration, and dual output pressure and temperature combinations.

Amplified Temperature Transmitters

Amplified Temperature Transmitters

Amplified temperature transmitters utilize stainless steel and heavy wall tubing to reduce the need for thermowells, minimizing costs and improving space efficiency. These units include analog and digital state-of-the-art electronics, coupled with rugged and durable RTD elements and a dual output pressure and temperature option.

Dual Output Sensors

Dual Output Pressure Temperature Sensors

These transducers combine both a pressure sensor and temperature sensor in one small, lightweight package. This design reduces your sensing costs and required space envelope by effectively eliminating the second sensor package. They can be configured with either analog and digital and industrial network output options.

As you begin your search for the right temperature transducer, one of the most important considerations is whether it will perform at the level you require. You need to find a product that has the capabilities to handle your specific application.

To do this, you will need to determine:

  • The temperature range to be measured
  • The operating media (fluid) to be measured
  • The temperature accuracy
     ◦  (+/-) Degrees
     ◦  (+/-) % of Reading
  • Determine the frequency response (or rise time constant) required
     ◦  Seconds in fluid to give true reading
     ◦  Function of probe parameters
  • The temperature units required by application
     ◦  Fahrenheit
     ◦  Celsius
     ◦  Kelvin
     ◦  Rankine
  • Over-Temperature Conditions
     ◦  Will temperature ever exceed the maximum range?
     ◦  By how much?
  • Physical Size
     ◦  Size Constraints
     ◦  Probe Length
     ◦  Location Access
  • Process Connection/Pressure Fitting
     ◦  What is the maximum working pressure of the system?
     ◦  Do I want to measure pressure while I’m at it?
  • Characteristics of the Media
     ◦  Corrosiveness
     ◦  Viscosity
     ◦  Velocity
     ◦  On/Off Cycling
  • Electrical output from the sensor
     ◦  Analog
         •  mV/V
         •  0-5 Vdc, 0-10 Vdc
         •  Bipolar Voltage
         •  Isolated or Non-Isolated Voltage
         •  4-20 mA current
     ◦  Digital
         •  RS485 (MODbus)
         •  RS232
         •  CANbus, J1939, CANopen
     ◦  Combination
         •  Analog and Digital
  • Electrical termination
     ◦  Connector, integral cable, flying leads
     ◦  Customer-specified
     ◦  Mating connectors & cable assemblies
     ◦  Connector/cable orientation
     ◦  Wiring codes and pin-outs
  • External Zero and Span Potentiometers
     ◦  Amplified Units Only
  • DIN Rail or In-Line Signal Conditioning
     ◦  mV/V units only
  • Type of Power Supply

The environment in which the temperature probe operates plays an important role in the choice of the sensor. In order to receive accurate readings, here are a few things you should keep in mind when choosing your sensor:

  • Operating Temperature Range
  • Compensated Temperature Range
  • EMI/RFI Conditions
  • IP or NEMA Rating Requirements
  • Hazardous Environment
     ◦  Intrinsically Safe
     ◦  Explosion-Proof or flameproof
  • Indoor or Outdoor Use – Enclosure rating?
     ◦  Exposure to the Elements
     ◦  Dust/Dirt
     ◦  Temperature Extremes
     ◦  Animal/Insect Exposure
  • Submersible
     ◦  Depth
     ◦  Fresh or Salt Water
     ◦  Case Pressure

Some systems may have specific requirements such as:

  • Calibration Requirement
     ◦  Standard 11-Point Calibration
     ◦  Special Calibration with Added Points
  • Special Approvals, Certifications, Testing, or Cleaning
  • Special Labeling Requirements
  • Frequency Response
  • Shock and Vibration Resistance
  • Serviceability
     ◦  How accessible must the unit be?
     ◦  How often will it require service?

What is the required Lead Time?

Lead time is impacted by a variety of factors including, but not limited to:

  • Design and Engineering Requirements
  • Special Components
  • Special Processed
  • Qualification Testing
