PyroCube G
Pyrometer for Glass Applications


  • Temperature ranges from 100°C to 2400°C
  • Measured spot as small as 2.2 mm
  • Response time as fast as 10 ms
  • Continuous LED sighting shows the position and size of the measured spot while readings are being taken
  • Multilingual touch screen interface (optional)

The PyroCube is an infrared pyrometer with an extremely fast response time and a very small measurement area size. It is available with or without the PM030 touch screen interface.

Field of View Diagrams

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. Accuracy specifications are valid up to the maximum distances shown.

Mechanical Specifications

-G models: 85 g
-GH models: 190 g

Environmental Specifications (PyroCube Sensor)

Environmental Rating
Operating Ambient Temperature
0°C to 50°C
Storage Temperature
-15°C to 70°C
Operating Ambient Humidity
30% to 85% RH non-condensing

Display Options

Model PM030 Optional touch screen terminal for indication, configuration, data logging and alarm outputs. Sensor is available with or without display.


The PyroCube G measures glass surface temperatures from 100°C to 2400°C.

Its measurement wavelength of 5 µm provides maximum accuracy when measuring glass. At this wavelength, reflections have the smallest possible effect on the accuracy of the measurement.

PCU-GH models have a fast response time of 10 ms, making it possible to measure glass gob temperature.



The PyroCube may be installed with or without the PM030 touch screen interface.

Electrical Installation

Dimensions (mm): -G models

PM030 Touch Screen Interface

Provides temperature display, alarm outputs, sensor configuration and data logging for one PyroCube sensor.

Mounting Bracket

The L-shaped fixed mounting bracket offers a rigid support for the sensor and allows fine rotational adjustment about one axis.

Protective Window

The protective calcium fluoride window helps prevent contamination and damage of the PyroCube sensor’s lens.


Air Purge Collar

Helps keep dust, moisture and contaminants away from the lens. Use clean (instrument) air.

Airless Dust Protector

Helps keep dust away from the lens. No air supply is required.

Extension Cable

5 metre long cable for PyroCube sensor, fitted with connectors at both ends.

Right Angled Mirror

Reflects the PyroCube sensor’s field of view by 90 degrees, making it easier to install in tight spaces. Includes a protective calcium fluoride window to keep dust from settling on the mirror and lens.

Water Cooling Jacket

Allows the sensing head to be installed where the ambient temperature is above 50°C. Includes an air purge inlet to stop condensation from forming on the lens. Please note that the sensor’s output cable is rated to 80°C.

PID Controllers

The analogue output of the PyroCube is compatible with any of our indicating controllers for closed-loop PID control.

The PyroCube sensor may be ordered with or without the PM030 touch screen interface.
