The new VL miniature infrared
temperature sensor is designed to offer maximum flexibility in the smallest possible package.
The VL can measure temperatures from -40ºC to 700ºC with a response time of just
180ms. It has a narrow 10:1 field of view, and adjustable emissivity so can be
configured to measure most materials.
Each unit offers a choice of either 0/4 to 20mA, 0 to 5V or type J or K thermocouple outputs so can be used with
virtually all process control instrumentation.

Under the lid of the electronics enclosure are buttons which are used to adjust the
configuration parameters of the sensor and set the temperature range, response
time and output. From here the analogue outputs can also be configured and
maximum/minimum readings switched on or off.
To compliment the analogue outputs the VL also provides a digital relay output, the
alarm level and hysteresis of which can be adjusted with the electronics module. The
VL also has an RS-485 interface for connection to a PC, and can be interrogated using the UPP® (Universal
Pyrometer Protocol).
The compact sensing head of the VL is made of stainless steel and is sealed to
IP65. It can operate in ambient temperatures up to 85ºC without cooling, or 200ºC with air-cooling and purging
accessories.
