DETAILED DESCRIPTION

PC21-151-301-WJ
For measuring temperatures without contact, this range of small infrared sensors is suitable for industrial applications. The steel housing complete with cooling sleeves can operate with high precision and linearity at ambient temperatures of between 140°C to 250°C. Different spots (reading areas) and temperature scales are available with output normalised at 4...20mA.
Accessories include air purge collars to keep the lens clean and fixed or adjustable brackets.
