Key Features

  • Series IN 5/5: pyrometers in two wire form with analog output 4 to 20 mA, several temperature ranges available 
  • High accuracy due to digital linearisation of the output 
  • Adjustable exposure time 
  • Compact housing

Details

The pyrometer IN 5/5 as well as the instruments of series IN 5/5 plus are specially designed for non-contact temperature measurement of glass surfaces and quartz surfaces.

The instruments differ in their specification:

The IN 5/5 is a digital pyrometer in two wire technique. This technique combines the high accuracy of the digital signal processing with the simple connection and operating with two wires.

Additionally to the analog output the plus types are digital pyrometers equipped with a digital interface, enabling temperature indication and storage on a PC. Also a temperature sub range can be configured and the instrument parameters can be adjusted remotely.

The version IN 5/5-L plus is equipped with optics with better fields of view for the measurements of small objects.

The high-speed version IN 5/5-H plus has a shorter exposure time of only 10 ms and is suited for fast measuring tasks.

For optimal match of the instrument to the application (size of the measuring object, distance) different optics are available.

For a precise alignment of the pyrometers to the measuring object, most of the plus types are equipped with a laser targeting light.

Typical Applications

  • Float glass
  • Hollow glass
  • Glass drop
  • Glass hardening
  • Glass bending
  • Bulb production
  • Heat treatment

Measurement Uncertainty:

Dependent on object temperature T and
ambient temperature Tamb (ε= 1, t90= 1s)
 

T < 1300°C:

0.6% (IN 5/5-Lplus: 0.8%) of reading in °C or 2°C (Tamb=15 to 30°C) *)
1% of reading in °C or 1.5°C (Tamb=0 to 15 or 30 to 63°C) *)

T=1300 to 1800°C: 

0.8% of reading in °C (Tamb=15 to 30°C)
1.2% of reading in °C (Tamb=0 to 15 or 30 to 63°C)

T=1800 to 2500°C: 

1% of reading in °C (Tamb=15 to 30°C)
1.4 % of reading in °C (Tamb=0 to 15 or 30 to 63°C)

*) Whichever value is greater. The instrument must be at a constant ambient temperature for a minimum of 15 minutes (30 min for IN 5/5-L plus for 200 to 1300°C at Tamb = 0 to 15 or 30 to 63°C) and has to be connected to the power supply.

Repeatability: (ε = 1, t90= 1 s)
 

0.3% of reading in °C or 0.6°C
(Whichever value is greater. The instrument must be at a constant ambient temperature for a minimum of 15 min. (30 min for IN 5/5-Lplus for 200...1300°C at Tamb= 0 to 15 or 30 to 63°C)

Noise Equivalent Temperature Difference
