  • Helps protect the sensor lens from mechanical damage
  • Helps retain lens fragments if the lens becomes damaged
  • Designed for Calex infrared temperature sensors
  • Suitable for 8 to 14 m measurement wavelength sensors
  • Compatible with sensors that have adjustable emissivity
  • Available in multiple models for different sensor families

Protect the lens of your Calex infrared temperature sensor with these protective windows, designed to help guard against mechanical damage and help retain lens fragments if the lens is damaged.

These protective windows are intended for use with Calex infrared temperature sensors that operate at a measurement wavelength of 8 to 14 m and have an adjustable emissivity setting.

Available Models

Model Mounting Thread Transmissivity (8 to 14 m) Ambient Temperature Range Window Material Holder Material
SIWS M16 x 1 mm 69% 0C to 180C* Silicon Stainless steel
PWS M20 x 1 mm 76.8% 0C to 100C* IR-transmissive plastic Stainless steel
PWL M20 x 1 mm 76.8% 0C to 100C* IR-transmissive plastic Stainless steel

*Do not exceed the ambient temperature limits of the sensor.

Compatibility

PWS / SIWS:

  • PyroMini*
  • PyroEpsilon
  • PyroBus
  • PyroCAN
  • PyroMiniUSB
  • PyroMiniBus

PWL:

  • PyroUSB* (PUA8 models)

*General Purpose models only. Not compatible with Short Wavelength models.

These windows are not suitable for use with sensors that have a fixed emissivity setting, such as the PyroCouple.

How to Use

  1. Mount the infrared temperature sensor as normal using the mounting nut supplied with the sensor.
  2. Ensure at least 3.5 mm of thread is available for the window holder.
  3. Screw the window in its stainless steel holder fully onto the lens of the sensor.
  4. Tighten the holder with a spanner.
  5. Adjust the emissivity setting to compensate for the window transmissivity.
  6. Apply the new emissivity setting to the sensor according to the sensor manual.
  7. Begin measuring temperature.

Emissivity Adjustment

To compensate for the window, multiply the target emissivity by the transmissivity of the selected window.

Example for PWS:

0.95 0.768 = 0.73

In this example, if the original target emissivity is 0.95, the corrected emissivity setting w
