Probe

Minco’s advanced probe technology and manufacturing capabilities support high quality and innovative solutions for aerospace, medical and industrial applications. Our selection of custom and standard probe sensors is available in a variety of configurations to meet specific application requirements for installation, performance, and reliability.

Design Type

A sensor’s construction has a large impact on its thermal time response, resistance to corrosive media and other key performance characteristics. By manufacturing the bare elements all the way through final assembly, Minco has the flexibility to design high performing temperature sensors, unique to each application. Temperature probes come in all shapes, sizes, and configurations. Below are a few options:

From Aerospace to Nuclear Power, Minco tackles the most critical and demanding product requirements. Minco’s diverse experience enables design optimization by integrating the fast responding and high reliability features from medical diagnostics equipment with the extreme vibration and temperature stability requirements of aerospace engine temperature sensors.

Minco’s assembly capabilities enable a streamlined sourcing partner for customized, value-add products. From industry standard configurations used in industrial oil and gas applications to custom plug-n-play temperature harnesses used in aerospace hydraulics, Minco engineering has the expertise to develop the ideal solution. In addition, Minco offers an extensive portfolio of hazardous area certified assemblies (IECEx, ATEX, FM, CSA) where additional safety is required in potentially dangerous environments.

Minco’s sanitary sensors are authorized to carry 3-A symbol for sanitary applications, including food, beverage, and pharmaceutical processing. These sensors come in three main styles, including probe, connection head assembly, and thermowell assembly.

Cases, made of polished 316 stainless steel, are free of cracks and crevices that might shelter bacteria. External cables will withstand wash-down and offer an optional stainless steel armor to prevent abrasion wear. Epoxy coated aluminum connection heads available for terminating leads to external wiring and housing a temperature transmitter. The fast-response thermowell assembly lets you remove the RTD probe without breaking into the process lines. Flanges are designed to install with the Tri-Clamp sanitary cap fittings.

Small, rugged temperature sensors withstand rough handling and harsh environments. Designed for easy installation, these sensors can be mounted directly on machines, against process pipes, or embedded directly into a machined part. Miniature sensors are ideal for process control measurements, test and verification of existing systems, and retrofitting existing machines.

  • Embedment sensors are no larger than many bare ceramic elements. These sensors have a metal case and insulated leads to withstand rough handling and harsh environments. They are easy to install in drilled holes for applications ranging from bearing shoe temperature monitoring in industrial rotating equipment to heat-sink temperature of PCR equipment in clinical laboratories.
  • Bolt-on and economy sensors have the widest variety of designs and features. The highly customized profiles and fast time response capability makes these sensors ideal for applications ranging from semi-conductor chip temperature detection to temperature profiling of medical DNA sequencing equipment.

Materials: Minco utilizes advanced CAD/CAM machining for economic production of cases, fittings and assemblies. We have expertise working with a variety of materials, including: Stainless steel in various grades, Brass, Copper, Monel, Hastelloy, Titanium, Rubber, PTFE, and plastics.

Surface plating with nickel, gold, and other metals enables the use of high-conductivity sheaths with the added resistance to corrosion for superior performing temperature sensors.

Element

Element Type: Minco can supply sensors to work with nearly any type of instrument option.

  • Resistance Temperature Detectors (RTDs)
    • Platinum RTDs with wide range of TCRs
      • Range from 0.00375 to 0.003927
      • 0.00385 (Minco element "PD") is most popular
    • Nickel, copper, and nickel-iron RTD elements
    • Non-standard resistance-temperature curves
    • Base resistances up to thousands of ohms
    • Thin film or wire wound constructions
  • Thermistor temperature sensors
  • Thermocouple temperature sensors
  • Integrated Circuit temperature sensors

Resistance temperature detectors (RTDs): An RTD sensing element consists of a wire coil or deposited film of pure metal. The element’s resistance increases with temperature in a known and repeatable manner. RTDs exhibit excellent accuracy over a wide temperature range and represent the fastest growing segment among industrial temperature sensors. Their advantages include:

  • Temperature ranges from -260 to 650°C (-436 to 1202°F).
  • Repeatability and stability: The platinum resistance thermometer is the primary interpolation instrument used by the National Institute of Standards and Technology from -260 to 962°C. Ordinary industrial RTDs typically drift less than 0.1°C/year.
  • Sensitivity: The voltage drop across an RTD provides a much larger output than a thermocouple.
  • Linearity: Platinum and copper RTDs produce a more linear response than thermocouples or thermistors. RTD non-linearity can be corrected through proper design of resistive bridge networks.
  • Low system cost: RTDs use ordinary copper extension leads and require no cold junction compensation.
  • Standardization: Manufacturers offer RTDs to industry standard curves, most commonly 100 Ω platinum to EN60751 (Minco element code PD or PE).

Thermocouples: A thermocouple consists of two wires of dissimilar metals welded together into a junction. At the other end of the signal wires, usually as part of the input instrument, is another junction called the reference junction, which is electronically compensated for its ambient temperature.

Heating the sensing junction generates a thermoelectric potential (emf) proportional to the temperature difference between the two junctions. This millivolt-level emf, when compensated for the known temperature of the reference junction, indicates the temperature at the sensing tip.

Thermocouples are simple and familiar. Designing them into systems, however, is complicated by the need for special extension wires and reference junction compensation. Thermocouple advantages include:

  • Extremely high temperature capability: Thermocouples with precious metal junctions may be rated as high as 1800°C (3272°F).
  • Ruggedness: The inherent simplicity of thermocouples makes them resistant to shock and vibration.
  • Small size/fast response: A fine-wire thermocouple junction takes up little space and has low mass, making it suitable for point sensing and fast response. Note, however, that many Minco RTDs have time constants faster than equivalent thermocouples.

Thermistors: A thermistor is a resistive device composed of metal oxides formed into a bead and encapsulated in epoxy or glass. A typical thermistor shows a large negative temperature coefficient. Resistance drops dramatically and non-linearly with temperature. Sensitivity is many times that of RTDs but useful temperature range is limited. Although rare, thermistors are also available with positive temperature coefficients. Linearized models are also available.

There are wide variations of performance and price between thermistors from different sources. Typical benefits are:

  • Low sensor cost: Basic thermistors are quite inexpensive. However, models with tighter interchangeability or extended temperature ranges often cost more than RTDs.
  • High sensitivity: A thermistor may change resistance by tens of ohms per degree temperature change, versus a fraction of an ohm for RTDs.
  • Point sensing: A thermistor bead can be made the size of a pin head for small area sensing.

Integrated Circuits (IC): An IC chip is a silicon-based temperature sensor that produces an output current proportional to absolute temperature. Due to the reduced temperature range, when compared to RTDs and Thermocouples, IC sensors are traditionally used on circuit boards and other electronics. These sensors offer analog or digital outputs with modest accuracy at a low cost.
