DETAILED DESCRIPTION

PC21-151-301
For measuring temperatures without contact, this range of small infrared sensors is suitable for industrial applications. Within the steel casing, they can operate with good accuracy and linearity in ambient temperatures of up to 50°C. A range of spots (reading areas) are available as well as two temperature scales with normalised output 4...20mA.
Accessories include air purge collars to keep the lens clean and fixed or adjustable brackets. The addition of the power terminal available on Pixsys instruments simplifies wiring and allows direct 2-wire connection.
