OVERVIEW
Measure temperatures from -20°C to 500°C with precision optics
PyroMini OEM non-contact infrared temperature sensors measure temperatures from -20°C to 500°C and provide a choice of analogue outputs.
The miniature sensing head of the PyroMini OEM has a right-angled cable entry, allowing it to be installed where space is limited.
An ambient temperature rating of 0°C to 120°C allows use in applications such as dryers and curing machines where the air temperature is high.
Non-reflective, non-metallic materials such as paper, textiles, food, thick plastics, rubber, organic materials and painted surfaces can be measured accurately with the PyroMini OEM.
Metal surfaces can be measured, provided they are painted or coated first.Features
- Miniature sensing head withstands up to 120°C ambient temperature without cooling
- Measurement ranges from -20°C to 500°C
- Choice of outputs: 4-20 mA, 0-10 V DC, Type J or K thermocouple
- Right-angled cable entry for low-profile installations
- Stainless steel sensing head, sealed to IP65
- Fixed emissivity 0.95 – suitable for measuring most non-reflective non-metals, and painted surfaces
- Not designed or approved for fever detection
Characteristics
Simple – Save installation time and reduce the cost of instrumentation on the machines you build with the PyroMini OEM.
Easy – This simple sensor works straight out of the box with no configuration necessary.
Accurate – Fixed emissivity setting provides accurate measurements on non-reflective materials such as paper, foodstuffs, organic materials, rubber, painted surfaces (including painted metals) and thick plastics.
Compact – Install the sensor where space is limited. The sensing head measures just 55 mm long, with a right-angled cable entry.
Industry standard outputs – A choice of robust industrial analogue outputs including 4-20 mA, thermocouple or voltage allows the sensor to be connected directly to an existing temperature indicator or controller.

APPLICATIONS
The PyroMiniOEM is ideal for use in a range of applications, such as:
Food industry
The PyroMini OEM’s non-intrusive design means this temperature sensor can be fitted to food manufacturing machines, taking up a minimum of space, and can be used without contamination of the product. This is all thanks to the compact 55mm non-contact sensing head.
Plastics
In the plastic manufacturing industry, thermoforming machines heat plastic sheets to make them malleable. Provided the plastic is thicker than a millimetre or so, it can be measured easily using a general purpose sensor (contact Calex for specialised sensors for thinner plastics).
To integrate a PyroMini OEM sensor into existing machinery monitoring systems, there is a choice of four analogue output options.
Wood Processing
Timber workpieces in wood manufacturing machines are constantly on the move, and as such contact temperature probes would not be suitable. Wood temperature can be measured in processes such as sawing, sanding and planing to help indicate worn cutting surfaces.
Textiles
Calex sensors are commonly used in measuring textiles with success. Industries such as textile manufacturing deploy temperature sensors to their production machinery, to monitor fabric web temperatures as well as the equipment itself such as coated rollers. Steel rollers can be measured using the PyroMini OEM if a band is painted (to measure bare steel, consider the PyroUSB).
Machinery such as screen-printers, dryers and tunnel finishers will benefit due to the need for continuous temperature monitoring.
Enclosed Spaces
A small sensing head with a right-angled cable entry allows for the discreet installation of the PyroMini OEM into most spaces. The sensor can be installed in a 16 mm hole via the included mounting nut, and optional mounting brackets are also available.
