Infrared temperature sensor suits semiconductors and metals
Calex Electronics is launching the cost-effective PyroMini 0.9 infrared pyrometer for non-contact temperature measurement on reflective metals and semiconductors as low as 350degC.
The new pyrometer can view into a vacuum chamber through a quartz or glass window and measure the temperature of the surface of the silicon wafer. Temperature ranges from 350 to 2000degC are available, and the low-temperature 350-800degC model creates new opportunities for temperature monitoring and control in silicon wafer processing.
Stable and repeatable measurements can be taken continuously for long periods with a fast response time of just 240ms. With the optional MicroSD Card installed, over a year's worth of data can be logged, even at the fastest sample rate of one reading per second.
High accuracy is provided by the pyrometer's short-wavelength detector, which ensures that any error in emissivity setting or change in emissivity has the minimum effect on the measurement.
Miniature sensing head:
- Dimensions 18x45mm, 316 stainless steel, sealed to IP65
- Cable lengths up to 30m
Electronics module with optional touch screen:
- Large, bright temperature display
- Visual alarm indication
- Scrolling temperature graph
- Full sensor configuration
- Basic models available without a screen
Outputs:
- Choice of 4-20mA or RS485 Modbus output
- Two alarm relays on touch screen models that could be connected to alarm equipment directly, without a separate trip amplifier
Accessories available include mounting brackets, air purging and laser sighting.
