Non-Contact Infrared Temperature Sensor with Analogue Outputs

The PyroCouple is a simple infrared temperature sensor with a choice of analogue outputs. No complicated setup is required - just connect a temperature indicator and power supply, and instantly start taking measurements. It is suitable for non-contact temperature measurement on most non-reflective non-metal surfaces, such as paper, thick plastics, asphalt, painted surfaces, food, rubber and organic materials, among many others.

PyroCouple non-contact infrared sensors measure temperatures from -20°C to 500°C and provide either a linear 4 to 20 mA output, a voltage output or a thermocouple output. This range of output signals is compatible with almost any indicator, controller, recorder, data logger etc., without the need for special interfacing or signal conditioning. They are suitable for most materials such as food, paper, textiles, plastics, leather, tobacco, pharmaceuticals, chemicals, rubber, coal and asphalt; but not materials with a low emissivity, for example polished metals. Two-wire and four-wire versions are available:

Two-wire PyroCouple sensors transmit the target temperature as a 4-20 mA output and offer a simple solution for most applications.

Four-wire PyroCouple sensors transmit the target temperature as a 0-50 mV or thermocouple output (type J or K) plus the internal sensor temperature as a 4-20 mA output. This second output can be used to ensure that the sensor is being operated within the correct ambient temperature limits and prevent damage caused by overheating or overcooling. It can also be used to give an approximate indication of the air temperature surrounding the sensor.

Features:

Temperature ranges from -20°C to 500°C
Two-wire 4-20 mA output or four-wire voltage/ thermocouple output
Choice of precision optics for large or small targets
Fast response with high stability
Stainless steel housing, sealed to IP65
Quick and easy installation
Wide range of accessories
Fixed emissivity 0.95 for measuring non-reflective non-metals, and painted surfaces (including painted or coated metals)
Conforms to industrial EMC standards
Ideal for measuring non-reflective non-metals, or painted metal surfaces
Not designed or approved for fever detection

Please note: The given measured spot size contains 90% of the energy detected by the sensor. We normally recommend the target is at least twice as large as the given measured spot for maximum accuracy. Sensors may be used at longer distances than the above diagrams show. There is no maximum measurement distance in clean air; this is because the PyroCouple detects only the wavelengths of infrared radiation that are not absorbed by the atmosphere.

Infrared Temperature Measurement in Paint Curing

In the painting of products such as automobile body panels, long term durability and consumer appeal depend on the quality of the coating application processes. This quality, determined by adhesion, hardness, corrosion reistance, finish and colour, depends largely upon curing temperature cycles. Calex's non-contact infrared temperature sensors are capable of giving the user or OEM tight control over this cycle, where none existed before.
