What are the Temperature probes?

Click to Expand

Temperature probes are sensors that monitor and control temperatures in a variety of commercial, residential, and industrial environments. Probes are placed on the surface or immersed in the substance they are measuring. They are particularly useful in process applications where fine temperature controls are critical for manufacturing quality products and operating equipment safely.

Temperature probe assemblies are designed for speedy installation and typically include sensors, sensor heads, transmitters, thermowells, and connectors. By incorporating ready-to-install assemblies, you save time on installation and reduce the potential for calibration errors. All of Digital Instruments’ temperature probes are pre-calibrated, so you can install the full assembly without having to worry about testing each probe component.

We assign unique model numbers to each of our probe assemblies, so you can order the exact assembly you need without having to source components from multiple manufacturers or distributors. With full temperature probe assemblies, you also reduce the amount of time and money spent on field wiring, compatibility checks, and assembly approvals.

All of our temperature probe assemblies are pre-certified, so you enjoy quicker installation and improved temperature measurement precision.

Temperature Probe Sensor Applications

Thermocouple
Thermocouple Applications

Thermocouples are ideal for use in applications where high temperatures are the norm. Common thermocouple applications include:

  • Food and beverage: Thermocouples control high temperatures for clean-in-place operations, penetration probes, ovens, hotplates, and steam kettles.
  • Extrusion and molding: Thermocouples can monitor the temperature in extrusion and injection molding operations, to ensure optimal temperature and pressure conditions.
  • Industrial and power generation: Thermocouples can be specially designed to measure temperatures from -200 °C to over 650 °C. This makes them perfect for furnaces, foundries, kilns, gas turbines, and exhaust systems.

Resistance Temperature Detector
RTD Applications

Resistance Temperature Detector

Industrial RTD temperature probe sensors are ideal for applications that require a high degree of precision and repeatability. Applications that typically use RTD sensors include:

  • Automotive: RTDs are found in air conditioners, exhaust and emissions systems, engine and oil temperature sensors, external temperature sensors, and electric vehicle engines and batteries.
  • Electronics: Communication systems and sensitive electronic instrumentation use RTD sensors to regulate the temperature of transistors, amplifiers, and stabilizers. They are also incorporated into consumer electronics and computers.
  • Aerospace: The aerospace industry uses RTDs for a wide range of temperature control and monitoring systems, including oil and fuel, turbines, brakes, engine oil, gear boxes, inlet air, and cabin climate control.
  • Military: RTDs are used in temperature transducers for fluid and gas monitoring in vehicles and aircraft, including lubrication systems, engine oil, fuel systems, hydraulics, landing gear, nitrogen generation, and environmental control systems.

Thermistor
Thermistor Applications

Thermistors are an excellent option for simple operations at moderate temperatures. Applications for thermistors include:

  • Manufacturing: Thermistors are incorporated into process systems as a failsafe temperature monitor. When temperatures rise above a certain threshold, the thermistor will break the circuit, providing a safety shutoff for manufacturing operations.
  • HVAC: Thermistors monitor and control internal environmental conditions in residential, commercial, and industrial facilities, for enhanced comfort, safety, and energy efficiency.
  • 3D printing: 3D printing requires precisely controlled temperatures. Thermistors provide the level of temperature control necessary for 3D printers to produce cohesive, high-quality products.
  • Medical devices and equipment: Thermistors provide highly sensitive monitoring for critical patient operations such as vitals monitors, dialysis equipment, and catheters.
  • Food and beverage: The food and beverage industry uses thermistors to maintain correct processing temperatures consistent with product quality requirements and FDA standards.
