Infrared temperature sensor fits tight
spaces
Compact, two-piece infrared temperature sensor offers a wide choice of analogue outputs, alongside a relay output and RS-485 interface, and it fits into limited spaces.
The new VL miniature infrared temperature sensor from Calex Electronics is designed to offer maximum flexibility in the smallest possible package This advanced sensor has an ultra-compact sensing head for use in the most confined of spaces, and a separate electronics unit with a backlit LCD display

IR temperature sensor mounts just where you want
One of the most striking things about the new Convir IL Series infrared temperature sensor is its small size; at just 105mm long and 25mm diameter it can easily be mounted just where you need it
Handheld infrared thermometers have laser sighting
A range of low cost, handheld infrared thermometers with laser sighting and a large backlit LCD display have various temperature ranges to suit different applications.
The VL can measure temperatures from -40 deg C to 700 deg C 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 allowing them to be used with virtually all process control instrumentation.
Under the lid of the electronics enclosure are controls which are used to adjust the configuration parameters of the sensor and set the temperature range and response time.
From here the analogue outputs can also be configured and maximum/minimum readings switched on or off.
To compliment the range of analogue outputs the VL also provides a digital relay output, the temperature 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 85 deg C without cooling, or 200 deg C with air-cooling and purging accessories.
