RTD Manufacture

Resistance Temperature Detectors (RTDs)

Sensing Devices’ RTD design and manufacturing business operates in tandem with the in-house production of ceramic and flat-film detectors as the core component of the sensors.

Our detector producing expertise ensures the accuracy, repeatability, and stability of every RTD manufactured and assembled in-house and our processes are quality assured to ISO:9001:2015. We utilise our onsite UKAS accredited calibration laboratory to evaluate the RTDs every stage and can offer uncertainties as low as ±0.6mK over the range –85°C/650°C.

Specialised in-house RTD manufacture

We design and manufacture temperature sensors and RTDs for specialised and high-precision applications across a wide range of sectors. Complete RTD assembly is carried out in-house. This includes component machining, element manufacture, and assembly calibration to UKAS where required. This turnkey approach to each component ensures the reliability and accuracy of the finished RTD.

  • Terminal Head

    RTD connecting heads are mountings for a terminal block or transmitter and can be supplied as General Purpose rated metals and composites for a wide range of uses. We also manufacture and supply ATEX and IECEx approved explosion-proof components.
  • Thermowell

    Dependant on what is being measured, and the type of sensor, the element is typically housed in a sheath or probe made from materials such as glass, alumina, aluminium, brass, copper and 316L stainless steel.

RTD SPECIFICATIONS

Sensing Devices has over 300 RTD designs on-record for a wide range of applications. The temperature range of each RTD is specific to the insulating materials used and the sensor design. Our inhouse design team help clients with the specification and design of sensors for practically any application.

The company is ATEX and IECEx approved for the manufacture of RTDs. We supply a range of customisable RTDs that can be issued with ATEX & IECEX certification.

RTD APPLICATIONS
Close Tolerance RTDs

We specialise in the manufacture of close tolerance RTDs, frequently to 1/20th DIN tolerance, (i.e. 0.07°C at 121°C). Producing RTDs to these close tolerances offers significant advantages and cost savings in critical applications and processes, such as those used in fermentation, solvent recovery, and sterilisation processes.

Resistance Temperature Detectors are used widely across electrical and mechanical equipment, most commonly in engines, generators, computers, and processes such as pharmaceutical and food production.

  • Food production
  • Pharmaceutical production
  • Textile production
  • Plastics processing
  • Air, gas and liquid temperature measurement
  • Semiconductor processing
