Product Details
Description
The PyroCouple is a simple, robust 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. The range of output signals is compatible with almost any indicator, controller, recorder, data logger etc; without the need for special interfacing or signal conditioning.
All sensors come with a 1m cable and a mounting nut. The sensor can be mounted on brackets or cut outs of your own design, or you can use the adjustable mounting bracket accessory (ABS). The air purge collar (APSN) is used to keep dust, fumes, moisture, and other contaminants away from the lens. It must be screwed in fully.
PyroCouple Features:
- Temperature range: -20°C to 500°C
- Fixed emissivity setting: 0.95
- 4-20 mA, Type K or J thermocouple, or 0-50 mV output options
- Fast response with high stability
- Stainless steel 316 housing
- Sealed to IP65
- Ideal for measuring non-reflective non-metals, or painted metal surfaces
The PyroCouple is an ideal general-purpose sensor for a huge range of applications.
Typical Applications
- Food
- Asphalt
- Paper
- Plastics
- Power industry
- Microwave dryers
- Infrared curing of paint and adhesives
- Condition monitoring
- Leaf temperature
- Tyre manufacturing
- Gas cylinder filling etc.
